초록

The power meter, required in most utility grid connectged applications to measure load consumption, is utilized to provide a feedback to an associated turbogenerator power controller, providing a control system for peak shaving, load following, reactive power control, reverse flow protection and load analysis for scheduled turbogenerator operation. This control system operates with simple discrete signals for peak shaving operation, to more complex pulse signals for load following, to load profile analysis and scheduled operation based on a microprocesso...
