Controls for Emergency Power, Peak Shaving, Utility Paralleling, and Prime Power/Cogeneration

Russelectric custom designs and builds low- and medium-voltage power control systems to meet the stringent performance and reliability requirements of data centers, hospitals, airports, communications, energy, defense, and other mission critical facilities.

In addition to controlling emergency power, systems can be designed for a variety of sophisticated control schemes such as peak shaving, load curtailment, and utility paralleling using live-source closed- transition retransfer and system test to avoid disturbing the load. Prime power and cogeneration systems are also available. Systems include sensors to monitor volts, amps, watts, frequency, and other electrical power data as well as controls for automatic prime mover starting/ stopping, status, and alarm annunciation; synchronizing; and priority load control. Load demand for fuel management and other controls are available as options.

Controls can be furnished for any major manufacturer’s engine generator sets.

Emergency Generator Control Systems

• Upon receipt of loss of normal power source signal from automatic transfer equipment, system automatically sends command to start engine generators.

• The first generator set to reach pre-set voltage and frequency is connected to the bus by closing its circuit breaker.

• System permits first priority loads to transfer to the connected engine generator set, while delaying the transfer of lower priority loads until additional generator capacity has been connected.

• System manages random paralleling of remaining generator sets to the emergency bus through their individual synchronizers and circuit breakers.

• System signals lower priority loads to transfer to the emergency power system as generator sets are added to the bus.

• System manages the shedding of low priority loads if a generator set fails during emergency operation, thereby assuring continuous power to the high priority loads.

• Upon receipt of signal from transfer equipment that it has retransferred to the normal source, system alerts generator sets to disconnect and shut down.

• Alarm and failure system, including annunciation, automatically shuts down an engine generator if required.

• Redundant PLCs ensure uninterrupted automatic system control — even if one fails.

• System design allows manual start and synchronization of generator sets if automatic controls malfunction.

• LCD HMI touchscreen displays, system one-line, alarms, setpoints, etc.

• Optional load demand sensing determines the number of engine generators in operation based on the actual load.

Chairman John Russell commented, “We want to thank George for his wise stewardship.  We also want to welcome Dorian, who is committed to running and growing the company in the spirit my father — independently-owned, innovative, and uncompromising on quality.”

 

Founded in 1955, Russelectric Inc. designs and manufactures integrated emergency and standby power control systems for mission critical facilities.  Manufactured at facilities in Hingham, Massachusetts, and Broken Arrow, Oklahoma, the company’s sophisticated power control systems, transfer switches, and bypass/isolation switches are widely used in advanced data centers, banks, hospitals, and other vital installations.

Russelectric® RTS-30 Series Bypass/Isolation Switches are UL labeled and listed for 30-cycle closing and withstand ratings based on testing per UL Standard 1008.  Available in continuous current ratings from 100 to 3000 amps, these switches dramatically simplify the selective coordination of overcurrent devices in backup power systems for healthcare and other mission-critical facilities.

The 30-cycle rating of Russelectric RTS-30 Series Bypass/Isolation Switches allows downstream overcurrent protective devices to clear a fault before upstream devices.  Consequently, they greatly simplify the engineering task of selective coordination mandated by the National Electrical Code for emergency and legally required standby systems.  No other manufacturer offers such a comprehensive range of 30-cycle & 3-cycle-rated bypass/isolation switches.  All RTS Series switches come equipped with the new RPTCS — the industry’s most powerful, most versatile microprocessor-based transfer control system.

Russelectric RTS-30 & RTS-03 Series Bypass/Isolation Switches combine an automatic transfer switch with a manual bypass/isolation switch that allows the transfer switch to be isolated for inspection, maintenance, repair, or testing. The bypass/isolation switch is designed to also function as a manually operated backup transfer switch when the unit’s automatic transfer switch (ATS) is disabled or de-energized.  With the bypass/isolation switch above the ATS, Russelectric’s vertical space-saving design reduces the unit’s footprint.  Feeder connections are housed in a third compartment accessible through a rear panel or door, and the compartments are separated by barriers to protect personnel.  The ATS is on casters so that, once it has been bypassed and isolated, it can be rolled out of the enclosure safely and easily.

RTS-30 & RTS-03 Series Bypass/Isolation Switches are available in versions for open-transition (with Russelectric’s proven break-before-make operation) and closed-transition transfer as well as load-break and no-load-break bypass.  In fact, Russelectric is the only manufacturer to offer both load-break and no-load-break bypass switches.  Open-transition versions are available with single or dual operators.  They are also available with an external manual operator which allows manual operation of the switch with the door fully closed for greater arc flash protection.

Standby Power System at Florida VA Hospital Covers All Electrical Loads

Few if any hospitals have a better power system than the James A. Haley Veterans’ Hospital in Tampa, Florida, thanks to its recently renovated power plant.  Completed at a cost of $47 million, it includes SCADA and a backup system capable of covering all electrical loads for 120 hours (without refueling) in the event of an outage.

A teaching hospital affiliated with the adjacent University of South Florida College of Medicine, Haley Hospital provides a full range of patient services with state-of-the-art technology and research.  It has 548 beds, plus another 118 beds in an on-site long-term care and rehabilitation facility — the Haley’s Cove Community Living Center.  The busiest of four U.S. Veterans Administration (VA) polytrauma facilities in the nation, Haley serves a four-county area in which it also runs four outpatient clinics.

After Hurricane Katrina hit New Orleans in 2005, the VA called for bids to upgrade emergency/backup power systems at VA hospitals in hurricane zones — upgrades that could ensure continuous air conditioning, not just the operation of life-safety and other critical equipment.

For Haley Hospital, the winning bid for power control switchgear, transfer switches, and SCADA was from Russelectric®, based in Hingham, Massachusetts.  Russelectric® designs, builds, commissions, and services on-site power control systems for hospitals, data centers, Internet service providers, airports, and other mission-critical facilities.  Systems can provide sophisticated control functions such as emergency/standby power, peak shaving, load curtailment, utility paralleling, cogeneration, and prime power.  All Russelectric® systems are supported by the company’s factory-direct, 24-hour field service.

Extra Layer of Confidence

The hospital’s administration is pleased with the new power system, which provides many more capabilities than the previous system.  Although there has not been an unexpected utility outage since the system became fully operational in May 2010, Byron Taylor, the hospital’s Lead Power Plant Operator, appreciates the extra layer of confidence.  At Taylor’s side to oversee the system, as they were throughout the planning and installation process, are Engine Technician Kyle Graley and Electrical Shop Supervisor Bill Hagen.

“We’ve had some storms come through, and it has been really nice because we do not have to worry,” says Taylor.  “One time, we saw the storms coming and TECO [Tampa Electric Company] asked us to drop off the grid.  We fired up our generators, and we operated on our own power for 17 hours, while TECO concentrated on restoring power to its residential customers.  That sort of thing has happened several other times for shorter periods, and there has never been a problem.”

Hagen particularly appreciates the quality of the power from the backup system.  “We get more blips from TECO than we do from our system,” he quips.  “It is exceptionally smooth.”

The hospital’s former backup power system included nine on-site generators, yet it could only cover life-safety loads — 45% of the hospital’s total load — in the event of a utility outage.  Hagen has no fond memories for the old system, which he calls “a major headache,” least of all for the system’s dynamic matrix control.  “We had nothing but problems with it,” he recalls.  “We never got it to work in parallel.  It couldn’t even generate a monthly testing report.”

In contrast, the new backup system covers everything — every load for nine buildings, 15 trailers that make up an on-campus clinic, and a parking garage — with just seven new 13,200-VAC Caterpillar diesel generators.  Supplied by Ring Power, the generators produce 2,200 kW each.

Another improvement is the hospital’s renovated fuel system.  The former system had a capacity of 22,000 gallons, and the storage tanks were spread out over several locations.  Today, a new tank farm has four 12,000-gallon tanks.  With another 6,000-gallon tank under each generator, the system has a capacity of 90,000 gallons.

Still more improvements are in the works.  As of now, Haley Hospital receives no rebates or preferred rates from Tampa Electric Company, and the agreement between the entities does not allow the hospital to feed power back to the grid.  But that agreement could change someday.  On the roof of a parking garage, the hospital will be installing photovoltaic cells expected to generate another 500 kW of power.  Newly installed solar panels in the adjacent parking lot near the long-term care facility (Haley’s Cove) will supplement that building’s utility feed by up to 500 kW, so the new cells will boost Haley’s photoelectric output to a total of 1 MW, enough to illuminate two parking lots.  Although feeds from the solar panels are lost when the hospital’s generators take over, under everyday conditions the new panels might provide surplus power that would enable the hospital to sell some power back to TECO.  A peak-shaving arrangement with the utility is also likely in the near future, according to Taylor.

The Power of Information

Also very important to the power control system upgrade is the new state-of-the-art Russelectric® SCADA system, which includes software and screen displays that Russelectric® customized for the hospital’s needs.  It provides interactive monitoring, real-time and historical trending, distributed networking, alarm management, and comprehensive reports around the clock for every detail of the entire power system, not just for the backup components.

In addition to monitoring power quality, the SCADA system’s many functions include continuous monitoring of fuel consumption by each generator and the level of fuel in every tank.  With Russelectric® SCADA, an operator can easily monitor and control a facility’s entire power system using full-color “point and click” interactive computer-screen displays at the system console.  For example, the operator can access and change the system’s PLC setpoints, display any of the analog or digital readouts on switchgear front panels, run a system test, or view the alarm history.  A dynamic one-line diagram display uses color to indicate the status of the entire power system, including the positions of all power switching devices.  Operating parameters are displayed and updated in real time; flashing lights on the switchgear annunciator panel also flash on the SCADA screen.  Event logging, alarm locking, and help screens are standard.

“The SCADA is so sensitive that it detects and explains even the slightest anomaly, including those in the utility feed,” says Taylor.  “A number of times we’ve called TECO because we saw something happening, and they had no idea they even had a problem yet!  The stuff the system does is phenomenal.  It gives us more data than we ever need for an average day, but it’s tremendous that we have it when we do need it.”

Freedom to Test the System

In accordance with state and federal regulations, the backup generators are tested every month.  Thanks to the new system’s capability for closed-transition transfer, the tests inconvenience no one.  Because there is no interference with hospital loads, there is no “blip” (power interruption).

The system gives Taylor and Graley the luxury of carrying out the tests in two different ways.  They can parallel the output of all seven generators to the utility feed, or they can test one generator at a time, up to its full output, by way of a special 2-MW load bank that has an independent control panel.  Testing can be initiated manually or through SCADA.

“It’s so much easier now,” says Hagen.  “We’ll never again have to pay a testing firm to come out and test an engine to make sure it meets all the requirements.”

Unlike most hospitals, Haley has the luxury of four utility feeds.  On a normal day, it draws from two of these (primary) feeds.  This means that, except for testing, Haley does not have to start its generators until it loses three or more utility feeds.
With advance notice from the utility that an outage is likely, Haley’s power plant personnel can now parallel the utility feeds with their own generators, then switch to on-site power seamlessly (closed-transition transfer).  But if there is an unexpected outage (and when the automatic transfer switches are tested), there will be a “blip” of 1 to 10 seconds, depending on the load.  For life-safety and other critical loads, the “blip” is only 1 to 3 seconds.  “Blips” for other loads are adjustable; most are set for 8-10 seconds.

Technical Support

Taylor and Hagen have high praise for Russelectric®’s field support services.  They recall working hand-in-hand with Jim Bourgoin, Russelectric®’s local Field Service Engineer, for seven months.

“During installation, Jim helped the contractors interpret the design whenever they were puzzled,” Hagen says.  “Afterwards, he stuck around to help us get things up and running.  It took a lot just to understand everything this system can do.  I already had a background in this, but it took quite a bit of training to really get up to speed.”

Taylor recalls, “There has not been one time when I have called Jim for an alarm or with questions about the system — whether at midnight or later — that he didn’t answer the phone and help me.  And on two occasions, he drove here at 3 or 4 in the morning to correct something that had gone wrong.  But it’s not just his responsiveness that’s impressed us.  The service he provides is exceptional, and it has been that way since day one.  To me, that’s worth just as much as the system itself.”

Taylor adds that Tom Crider, the local Russelectric® sales representative, was also deeply involved throughout the project, answering questions, facilitating the installation, and training Taylor’s staff.  Recently, with Taylor’s cooperation, Crider has led personnel from two other Tampa hospitals on tours of Haley’s power system.  One of those hospitals is installing a similar system.  The other is considering such an installation.

Onward and Upward

The fact that the system is designed to allow for modifications as the hospital continues to grow has Taylor thinking.  “With this new power system, we have seen what is possible,” he notes.  “It provides us with the information we need to analyze our power usage and consider new possibilities — opportunities we never would have considered before.”

Consulting-Specifying Engineer, November 2012 (Archived) — The continually evolving Smart Grid is becoming an automated, widely distributed power delivery network characterized by a two-way flow of electricity and information. As the Smart Grid grows, new technologies emerge that enable concepts to become reality. However, transformers are one of the Smart Grid’s weak spots because few of them have the ability to sense critical parameters such as voltage, current, and temperature; and few of them have communication capabilities. Transformers purchased today will likely be in service for more than 25 years and may not include the monitoring and communication capabilities that could be required within the next five years. Consulting and design engineers should be aware of the rapidly changing Smart Grid landscape and how it affects them and their clients.

Learning objectives:

  • The audience will how transformer technology is changing to facilitate bidirectional power flow in the Smart Grid.
  • Attendees will learn about solid-state transformers and their potential effects on Smart Grid operations.
  • Viewers will understand how utility infrastructure will need to change to accommodate solid-state transformers and bidirectional power flow.
  • Viewers will learn how monitoring of distribution transformer loading will affect the future Smart Grid.
