Sub.net flexibility provides measurements and performance analysis on Generators.
Aspects on the Generator can be monitored such as;
- Three phase voltages
- Three phase currents
- Droop currents
- Field excitation voltages
- Voltage stability
- Frequency stability
- Capability curve monitor
- Power Factor and harmonic effects
- Field voltage diagnostics
- Droop time constant response
Monitoring flexibility enables detailed analysis of Automatic Voltage Regulator and Governor Performance and load sharing interactions with multiple sets and ever more complex site loads require advanced monitoring and experience.
Generator trend and Threshold occurrence reports for kW, kVA, kVAR, PF and Harmonics provides data for optimum operation and better de-rating assessments.
Generators typically provide control of output voltage (VAR) and speed (kW).
When generators are paralleled, their voltage and frequencies are more critical. Sharing of load creates complexity particularly with harmonics and capacitance(active swing loads). Monitoring of field excitation levels validates the controls are functioning correctly or if/why instability has occurred or will occur.
