摘    要:为了分析二次扰动或多次扰动情况下继电保护的动作行为,需要精确模拟较长时间的电力系统故障暂态过程。该文应用自适应变换技术实现了适应不同暂态阶段仿真的元件模型转换,可以真实地仿真故障后的振荡过程,为分析保护动作行为提供了较长时间的故障波形。文中以LFP-901A型线路保护为例,应用自适应仿真的结果对其动作特性及其振荡闭锁元件进行了分析。结果表明:所提方法能够精确模拟较长时间的故障过程,为研究电力系统在复杂扰动情况下继电保护的动作行为奠定了基础。

关 键 词:继电保护  电力系统  动作行为  暂态计算  故障暂态  线路保护  动作特性  自适应变换  元件模型  仿真

Abstract:For analyzing the character of protective relaying on the condition of complicated faults and continualswitch operations, the long-term fault transient based onconcluding frequency change needs to be simulated accurately. The self-adaptive transform is used to realizing the transform of element models, which is suitable to different transientprocesses. It can simulate the swing transient caused by faultsand supply fault waves for protection analysis. By takingLFP-901A transmission line protection for example, the paperanalyzes the operation character and the swing blockcomponent of relaying protection. Result shows that thetransient self-adaptive simulation is suitable to the long-term transient on the condition of system swing and is important toanalyze protective relaying.
Keywords:Electric power engineering  Power system  Fault  Simulation calculation  Self-adaptive model  Protective relaying
