Abstract

The generation tripping sensitive point could be located by absolute kinetic energy incremental index. A method was proposed which is used to locate this point based on the estimation of unbalance power during short circuit period. The voltage was separated to two parts: one was determined by the pre-fault power flow, the other was determined by the equivalent voltage at the fault point. The voltages of the generators were calculated with superposition principle. Then the unbalance power of generators could be computed. The sensitive points of generation tripping were determined by this power. The effectiveness of the proposed approach is verified by simulation results of a ten-machine 39-bus system.
