摘要
二次系统仿真建模是电网调度员培训系统(DTS)的重要组成部分。以上海500 kV世博地下变电站为原型,介绍二次系统继电保护和安全自动装置的仿真建模方法.保护、开关和自动装置的模型都通过建立面向对象的类来实现.仿真方法主要采用逻辑判别法和定值判别法,对这2种方法从原理和优缺点方面进行阐述,分析它们各自的适用范围.并通过实例说明二次系统仿真的具体实现过程.
Simulation modeling of secondary system is an important component in dispatcher training systems（DTS）.This paper takes Shanghai 500 kV Expo underground substation as the prototype,it mainly introduces the simulation modeling method of the protection and security automatic device for the secondary systems.The models of protection,switches and automatic device are all built through classes Object-oriented.Logic judgment and fixed value judgment are two main simulation methods,their principles and characteristics are elaborated,and their scopes are analyzed.An example is given to illustrate the process of relay protection realization in the simulation.
