摘要:
      对四边形和方向圆特性阻抗继电器躲线路最大潮流的能力进行了详细分析,提出了距离保护负荷限制电阻的整定原则和整定方法,并给出了整定建议值。该方法已经在华北电网得到应用,可保证在电网潮流发生大范围转移时后备保护不误动作,避免引发连锁反应、扩大电网事故。
Abstract:
      This paper discusses the ability of avoiding maximal power flow of quadrilateral impedance relay and round impedance relay in detail. It puts forward the setting principle and method of load limiting resistor of backup distance protection and gives the propositional setting value of load limiting resistor. The setting method is applied universally in North China Power Systems, which guarantees that distance protection will not mal-operation and enlarges the fault’s range when the power flow of electricity grid diverts in a wide scope.
