带制动特性的电流差动母差保护分析

Analysis of Current Differential Busbar Protection with Bias Characteristics

变电站母线是电力系统中的重要元件之一。母线保护是保证电网安全稳定运行的重要系统设备,它的安全性、可靠性、灵敏性和快速性对保证整个区域电网的安全具有决定性的意义。结合在苏丹WADI变电站的AREVA MICOM P740母线保护调试中的经验,对AREVA MICOM P740带制动特性的电流差动母差保护进行分析。

The busbar of substation is one of the significant components in the power system. Busbar protection is the protection device, which can keep power grid stability, safety, reliability, sensibility and flexibility. The busbar protection ensures that the regional grid security has the decisive significance. Combining the experience of commissioning Sudan WADI substation AREVA MICOM P740 busbar protection,AREVA MICOM P740 bias characteristics of the current differential busbar protection is analyzed.
