Paper Abstract

A new principle for resonance measurement based on injecting resonant frequency signal is presented in this paper. By this principle, the grounding capacitance and grounding resistance can be measured on-line in ineffectively grounding power system. Based on it, Petersen-coil automatically tuning is implemented, and 100% stator grounding fault protection for generator stator windings is also proposed. The prototype for Petersen-coil tuning has been tested on the network for many years. As well as the new method for generator stator grounding fault is verified by simulation.
