Ensures no interruption of critical loads when transferring between power source assets

Hingham, MA - Russelectric, A Siemens Business, a leading manufacturer of automatic transfer switches and power control systems, offers its Paralleling System, ideal for ensuring that critical loads experience no interruption when transferring between all power source assets in renewable energy installations. The System can be configured for peak shaving and utility-sponsored load curtailment programs. The Paralleling System also offers high resiliency, power continuity and security for critical renewable energy installations.

Russelectric Paralleling Systems incorporate dual, redundant, hot synchronized programmable logic controllers (PLCs) for system control. Discrete switches, meters, and control devices are standard to allow manual control capability in the event that both system PLCs fail. With the Russelectric Paralleling System, users get soft loading transfer and phase lock synchronizing when paralleling with the utility, which reduces transients and controls the loading to the engine generators.

Russelectric provides basic or custom SCADA for local or remote monitoring of all power system functions. Custom SCADA systems allow users to monitor system operation, acknowledge alarms and review PLC setpoints. Realistic training simulators are also available.

All Paralleling Systems are UL listed. Selector switches are provided for open/closed transition, automatic/manual paralleling of generators and utility sources, and automatic/manual retransfer between both sources of power.

The Paralleling System offers a choice of either momentary paralleling with the utility or sustained paralleling for soft loading. Also available is paralleling of generator sets with the utility upon return of the utility source after power interruption.

System operation begins with testing in closed-transition mode with no interruption of the load. Generators are then paralleled with the utility and the load is transferred to them. Upon completion of testing, the load is retransferred through closed-transition to the utility source without disturbance.

These types of Utility Paralleling Systems can also be utilized in other applications, such as financial institutions, data centers, telecommunications, airports, healthcare facilities, and water and wastewater treatment plants.
