PARALLELING SWITCHGEARS.

When It Comes to Paralleling, We Carefully Consider Your Requirements and Custom Engineer the Perfect Solution.

BENEFITS OF USING PARALLELED POWER SYSTEMS.

MAXIMIZE YOUR SYSTEM’S FLEXIBILITY.

While it may be common for a facility to install a single large generator to meet its power needs, paralleling two or more generators offers a number of practical benefits and advantages over a single-generator system.

REDUNDANCY

The redundancy provided by the paralleling of two or more generators delivers greater reliability and flexibility than a single generator can provide. In critical applications, having more than one generator connected to the bus at all times ensures continuous generator power in the unlikely event that a generator fails.


EFFICIENCY

Instead of one large generator that might operate at an inefficiently low kW, several small generators can be paralleled together and turned on and off as necessary to efficiently support the varying demands of the load.

In situations where your load needs require one genset, you’ll run more efficiently. And that kind of efficiency can result in big savings. Because our ENCP 9 SERIES control systems automatically turns off any generators in your system when needs are low, you’ll benefit from immediate fuel savings and reduce running time for greater generator longevity.

POWER REQUIREMENTS

If the largest available generator is too small to meet your power requirements, two or more generators can be paralleled to provide the necessary power.

COST-EFFECTIVE

In many cases, paralleling two or more gensets to produce the same output as a larger single unit results in significant cost savings. For example, you can save up to 20% when paralleling three 500 kW units compared to one 1500 kW unit.

SPACE CONSTRAINTS

By using gensets with smaller footprints instead of one larger unit, the Paralleled Generators System provides greater location flexibility. the multiple units can be placed where a single genset won’t fit, so space is used more efficiently. And because the weight of multiple units can be distributed, rooftop installation is even possible - something you simply can’t do with many large single-generator sets.

FUTURE GROWTH

A Paralleled Generators System can be designed to add additional generators as your facility’s load requirements expand.

Purchase the Paralleled Generators System that fits your budget today. And, in the future, it can easily expand as your needs and budget allow. That way, you’ll never have to worry about replacing a system you’ve outgrown.

TYPICAL PARALLELING APPLICATIONS.

ELECTRONIL Provides the system with operating modes that meet the needs of your facility, whether you require simple standby power or multiple-utility paralleling and emergency power or prime power.

EMERGENCY/STANDBY.

The generators provide power in the event of a loss of utility service. Power transfer can take place at the transfer switch or by using the breakers in the switchgear.

The figure shows a typical ATS-Based emergency/standby power system. The generator power is combined onto the paralleling bus. Power flows through the feeder breakers in the paralleling switchgear to the emergency connection of the ATS.

SINGLE UTILITY SYSTEM.

The figure shows a typical single-utility system in which the entire facility is placed on generator power.

During a power outage, the utility main breaker opens; after a user-selected number of generators are online, the generator main breaker closes. The return to utility power can be open, closed or soft. Because the generator main breaker separates the load bus from the generator bus, the generators can be paralleled in test mode without affecting the load.

DUAL-UTILITY SYSTEM (LINEAR).

The figure shows a typical dual-utility system in linear configuration. If there is a loss of only one of the utility feeds, the system can be programmed to place that side on generator power, transfer all the loads to the remaining good utility or transfer the entire system to generator power. When the utility returns, the transfer back to utility can be open, closed or soft.

If the system is on generator power because both utilities fail and only one utility returns, the system can be programmed to return that side to utility power, return all loads to the one good utility or wait until both utilities return before automatically returning to utility power.

DUAL-UTILITY SYSTEM (RING).

The figure shows a typical dual-utility system in which the utility bus and generator bus are separate lineups. The available sequence of operations is similar to the linear dual-utility system.

The advantage of the ring dual-utility configuration over the linear configuration are:

  • The ability to feed the entire system with one utility feed without energizing the generator paralleling bus.
  • The ability to automatically respond to the generator’s main breakers failing to close and provide an alternate path to feed generator power to the load.

PRIME POWER.

The figure shows a typical generator based prime power system in which the entire facility is placed on generator power. The integrated power management feature optimizes the number of online generators based on the load’s kW demand, starting and stopping generators as required.

Generators are sequenced on in order of operator-assigned priority (or based on runtime) and taken off in reverse priority.

Operator-defined set points determine the percent load level and time delay at which the genset will be brought on or taken offline.
