Engine / generator set Utility / tie Manufactures
GENSET CONTROLLER FUNCTIONS
Engine start/stop, protection, metering, & control Generator protection, metering, & control Automatic synchronization kW and kVAR sharing, kW and kVAR control Multi-set communications Utility and tie control Expandable I/O with programmable logic (some)
ENGINE PROTECTION & MONITORING
Engine protection and monitoring methods
Digital inputs (switches) for pre-alarms and shutdowns, no parameter display Analog sensor inputs (VDO, DATCON, etc.), with parameter display J1939 CAN bus communications, with parameter display
ENGINE CONTROL
Starter output contact Fuel solenoid contact Magnetic pickup input (RPM) Cycle crank, over crank timers Cool down timer Warm-up timer Many other user settable timers Engine auto / manual switch Automatic speed matching synchronizing Governor biasing for kW sharing when paralleled with other gensets on an isolated bus and kW load control when paralleled to utility
GENERATOR PROTECTION
Reverse power Reverse VARS or over/under PF. (loss of excitation) Over/under voltage Over/under frequency Negative phase sequence Overcurrent, IEC IMDT curves (some) Ground fault (some) Fail to automatically synchronize
GENERATOR METERING
Amperage, each phase Voltage, each phase to phase Frequency Power factor kW, kVAR kWH, kVARH Synchroscope with bus voltage and frequency display
GENERATOR CONTROL
Circuit breaker trip and close output contacts Voltage regulator biasing (voltage setting) for kVAR sharing when paralleled with other gensets on an isolated bus and PF control when paralleled to utility Automatic synchronizing with voltage matching
UTILITY METERING
Amperage, each phase Voltage, each phase to phase Frequency Power factor kW, kVAR kWH, kVARH Synchroscope with bus voltage and frequency display
UTILITY CONTROL & PROTECTION
Circuit breaker trip and close output contact Loss of mains sensing Peak shaving Zero power transfer (ZPT) Base load Automatic synchronizing with voltage matching Utility protective functions (not utility grade)
Over/under voltage Over/under frequency Phase sequence

MULTI-SET CONTROL FUNCTIONS
First up sensing with dead bus closing kW / kVAR sharing Utility breaker control Tie breaker control (some) Load dependant start/stop
Spinning reserve and or % of load Service hours Multiple size genset kW ratings Pre-alarm starting
11
COMMUNICATIONS & SOFTWARE
User friendly software (some) Built-in USB port (some) RS232 / RS485 ports Modbus RTU Ethernet TCP/IP (some) CAN bus (controller area network) (most)
J1939 standard Variances between manufactures http://www.embedded.com/columns/murphyslaw/ 13000304 (for more information on CAN)
Most now have SCADA software available
