摘要
结合BP-2A母差保护动作原理与实际现场,分析母线区外故障引起母联误动的实际情况,其误动与一次设备及二次逻辑都密切相关,并对BP-2A母差保护的原理作进一步的分析和建议。模拟结果表明动作可靠性得到提高。
Based on bus differential protection through the device BP-2A theory and practice at the scene, this paper analyses external bus fault caused the actual situation of bus link circuit breaker misoperation. The maloperation is closely related with primary equipment and secondary system logic. This paper analyses and recommends device BP-2A bus differential protection theory Simulation results indicate that the action＇s reliability has been improved.
