摘要
为分析超高压输电线路距离保护动作特性的需要,本文提出了采用模分量法计算线路稳态故障,仿真接地距离继电器的动作行为。结合500 kV双端网络,详细分析了晶体管型多相补偿接地距离继电器在500 kV线路上的动作行为。
For the need of analyzing the characteristic of distance relays in extrahigh voltage transmission lines, the modul analysis method is used in faults computation for simulating the performance of ground distance relays. Combined with 500 kV two-terminal network, the performance of transistor polyphase ground distance relays in 500 kV transmission lines is detailedly analyzed.
