Product overview
The Woodward easYgen-3500XT-P2 combines generator control, engine protection, electrical protection, automatic synchronization, breaker control and load sharing in one configurable controller. It is designed for complex installations involving multiple generators, utility connections, bus-tie breakers and island operation.
Principal functions
- Automatic engine starting and stopping
- Generator and mains monitoring
- Generator-circuit-breaker synchronization
- Mains and generator-group breaker control
- Isochronous and droop load sharing
- Automatic mains-failure operation
- Peak shaving and import/export control
- Active- and reactive-power management
- Load-dependent generator starting and stopping
- Black-start and dead-bus operation
- Engine communication through SAE J1939
- Configurable protection, control logic and PID functions
- Communication with LS-5 and LS-6XT breaker controllers
Woodward specifies isochronous operation for systems containing 1–32 generator sets. Woodward easYgen-3000XT product page
