Abstract
A fail-safe operating method for a decentralized power generation plant DG includes determining a leakage capacitance of a generator of the DG before connecting the DG. The method also includes comparing the determined leakage capacitance with a predetermined first limit value, and connecting the DG to a grid only if the determined leakage capacitance is smaller than the predetermined first limit value. A decentralized power generation plant is configured to perform the method.
Claims17
A fail-safe operating method for a decentralized power generation plant (DG), comprising:
- determining a leakage capacitance of a generator of the DG before connecting the DG to a grid,
- comparing the determined leakage capacitance with a predetermined first limit value, and
- connecting the DG to the grid only if the determined leakage capacitance is smaller than the predetermined first limit value.
A monitoring system for a decentralized power generation plant (DG), comprising:
- an insulation monitoring device configured to determine a leakage capacitance associated with a power generator before connecting the DG to a grid;
- a circuit breaker device configured to receive the determined leakage capacitance or signal associated therewith and close a circuit breaker to connect the DG to the grid if the determined leakage capacitance is less than a predetermined first limit value.
