DTS中继电保护仿真模型的设计
|
摘要
定值比较法和逻辑比较法是调度员培训仿真系统(DTS)中继电保护仿真的主要实现方法,当前,单纯的使用其中一种方法很难同时满足继电保护仿真中实时性与逼真性的要求。采用定值比较法,有些参量(如零序电流,瓦斯含量等)难以得到;采用逻辑比较法,复杂网络线路之间的拓扑关系复杂,线路主保护与相邻线路后备保护之间的逻辑关系配合难以实现。本文分析了两种继电保护仿真方法的特点,形成了以逻辑法为主,定值法为辅的继电保护仿真设计思想,并基于该设计思想,按照电力系统不同类型的故障构建了相应的各类继电保护仿真模块。算例表明,用该方法设计的DTS继电保护仿真模型,能较好地满足仿真计算速度和仿真逼真性的要求。
The fixed value quantitative judging method and the logic judge method are mostly implementation ways in relay protection simulation in Dispatcher Training Simulator (DTS). Currently, the only use one of the ways is very difficult to satisfy the real-time requirements and simulation realistic demands. On one hand, some of the parameters such as zero-sequence current and the gas content are very difficult to get when the fixed value quantitative judging method just be adopt On the other hand, when engineers just use the logic judge method, it is hard for the logical relationship of the main line protection and the adjacent lines reserve protection to cooperate correctly because of the complex network topology relationships. In this paper, the characteristics of the two methods are analyzed and a new method that mainly based on the logic judge method together with the fixed value quantitative judging method is proposed. Based on the proposed method, the corresponding various relay simulation modules are founded. Examples show that these relay simulation modules can be used to meet the simulation speed and the simulation realistic of the requirements.
