Abstract
It happened in practice that when dead zone failures occurred in certain conditions, the BP-2B protection would make miscarriage of justice so to expand the outage dimension. Aiming at the hidden failure, this paper does analysis and finds out it is due to the logic of bus connection pre-closed, putting forward an improvement scheme for the logic so to avoid the maloperation of non failure bus and to limit the outage dimension, and thus to have certain engineering value.关键词
