摘　　要：结合电力系统仿真技术的新发展 ,论述了在变电站仿真器中实现微机保护仿真的必要性 ,并提出了基于面向对象技术的微机保护仿真的解决方案。具体实现微机保护仿真过程中采用了模块化的编程思想 ,把微机保护中共有的选相模块、功率方向模块、距离测量模块和重合闸模块都分离出来做成基本保护模块 ,其它的保护模块可以直接调用这些基本保护模块 ,从而提高了微机保护仿真效率。具体分析了在多线程编程环境中 ,应该注意的问题和解决方法。With the new achievements of power system simulation technology, the necessity of simulating microcomputer relay in substation simulator is explained and a solution to implement the simulation based on object oriented technology is presented. The modular programming technology is applied. The common modules of different microcomputer relays are separated out as basic protection modules,such as phase selection module, power direction module, distance measure module, re close module.Other modules can directly call these modules to greatly improve the simulation efficiency of microcomputer relays. The problems that could be met in multithread programming are analyzed and the ways to solve them are proposed.
