Paralleling

Switchgear And

Control Systems

IEM Paralleling Switchgear and Control Systems are designed and manufactured to deliver full control of custom-configured power generation systems. They integrate all facets of metering, protection, communication and controls to deliver peak performance, system reliability and operating economy.

IEM’s experience with generators and voltage regulators from all major North American manufacturers, governor systems for prime movers, and proprietary engine controllers results in efficient and innovative parallel switchgear designs for redundant power applications.

Types of Configured Power Systems

• Prime Power – where generators are the only source or main source of power

as in island-mode, marine, remote site or military type applications.

• Standby – where the generators serve as back-up to the main (utility) source,

commonly installed in hospitals, airport, data centers, waste-water/water

treatment facilities, including most life-safety institutional applications.

• Distributed Generation Systems – where generators are applied to supplement

the main source (as in peak shave applications) and may also act as the

standby system as well.

Intrinsic System Features

• Load priority control where loads are applied from a pre-determined

sequence, highest to lowest priority, based on system capacity and

characteristics.

• Generator operational control where only the pre-determined number of

generators are asked to start and carry load, either in a scramble or preset

start-sequence.

• Operator interface touch-screen terminals (OIT)/Human Machine Interface

(HMI) where system controls and interrogation can be accomplished at the

switchgear or from a remote network/PC/PLC.

• Remote communications in the most common industry protocols like

modbus/canbus and being fully conversant with industry leading

Ethernet/interface modules, comm-ports and RS 485 type connections.

• Utility paralleling system designs in passive closed transition (waiting for the

sources to become synchronized in voltage, frequency and phase angle), active

closed transition (where synchronization is dynamically controlled), soft load or

continuous base loading systems.
