| Abstract: | In the extra high voltage power network, the circuit breaker failure protection as a short-range backup protection has an important significance to the safe and stable operation of the power grid. In this paper, from the design specifications of failure protection, combined with failure protection to discuss some problems in actual operation, the problems existing in the main transformer medium voltage circuit breaker failure protection of 500kV Chucheng substation are analyzed in detail, and the improvement measures are put forward. The experimental results verify the correctness of the countermeasure, to effec- tively guarantee the safe and stable operation of EHV substation, having a certain reference value to solve similar problems of circuit breaker failure protection. |
