Thompson offers Caterpillar, Eaton, Russelectric, and ASCO switchgear and paralleling control products, which can support a wide variety of applications, or provide a custom designed system to meet your specific project needs. Thompson switchgear and paralleling control products provide a solution able to combine all elements of monitoring and control for Caterpillar generator sets in a single-source package. Thompson also provides custom switchgear and paralleling controls to meet specific customer requirements and functionality.
Paralleling up to 16 generator sets (MGDL operation) or up to 8 generator sets (hard wired operation)
Optional Control Panels: EMCP 4.4 Supervisory Control Panel (SCP)
Modes of Operation
The EMCP 4.4 can operate as a multi-generator set paralleling controller, with up to 16 generator sets synchronized and controlled on a common bus. Support is provided for both emergency standby and prime power operation. Features include automatic paralleling, dead bus arbitration, load sharing, and load sense-load demand.
Single Unit Utility Paralleling
The EMCP 4.4 can operate as a single generator set paralleling to a single utility. Support is provided for controlling both a generator circuit breaker and utility circuit breaker. Features provided include Emergency, Baseload, Import, Export, Peak Lopping Open Transition and Peak Lopping Closed Transition. Soft loading during closed transitions is automatically provided. Support is not available for multiple sources connecting to the bus beyond the single generator set and single utility connection
Automatic Paralleling
In the automatic paralleling mode, the EMCP 4.4 controller automatically adjusts the voltage and frequency of the generator set. When the generator output is synchronized with the second source, the EMCP 4.4 controller closes the generator circuit breaker.
Manual Paralleling
In the manual paralleling mode, the operator will manually adjust the voltage and frequency of the generator set. When the generator set is synchronized with the second source, the operator will initiate a generator circuit breaker close command. A 3-phase sync check function is also included to prevent out of phase paralleling.
Sync Check Mode
In the sync check mode, the EMCP 4.4 controller automatically adjusts the voltage and frequency of the generator set without closing the generator circuit breaker. When the generator set is synchronized with the second source, the operator will initiate a generator circuit breaker close command. A 3-phase sync check function is also included to prevent out of phase paralleling.
EMCP 4.4 MGDL Failsafe Load Sharing
The EMCP 4.4 is a robust genset controller that provides for onboard parallel functions using either hardwire interconnects or the multiple genset data link, also known as MGDL. The MDGL interconnect option offers several enhancements to the system that are not available using the hardwired method. However, what happens if there is a failure to communicate? What happens if communications is interrupted inadvertently or if the communication line is damaged or severed? The EMCP 4.4 controller strategy fail safe adaptive load sharing droop operation provides for parallel operation and load sharing during a loss of communication.
