| 摘 要： | 针对目前电力系统动态仿真分析中缺乏准确的继电保护模型、不能准确反映保护动作特性的问题.提出基于虚拟继电器的继电保护通用建模方法.虚拟继电器是对真实继电器的一种模拟,并可进行特定逻辑操作.文中采用分层次、面向对象的建模思路.建立起开放、透明的继电保护模型库,实现了含继电保护模型的动态仿真计算.该方法逻辑清晰,建模方便,可用于自定义建模,便于用户对所建模型进行修改和功能扩充.仿真结果表明:含继电保护模型的动态仿真程序能更加准确地反映实际电力系统发生扰动后的动态过程,可用于保护不正确动作引发的连锁事故分析、进行扰动后较长时间的事故重演、研究事故发生的本质原因以及正确的反事故措施等.
