摘　　要：具有可视化和自动化特性的继电保护整定计算软件大大提高了整定计算的效率。在分支系数计算模块中应用补偿法 ,修改阻抗矩阵时 ,使浮点运算减少了 2 /3;在整定计算模块 ,采用面向对象的开发方法 ,充分利用了 C+ +语言的封装、类、继承、多态等特性 ,使软件具有可靠性、可修改性。Visual and automatical relay coordination software for setting protection can im prove the efficiency of coordination work greatly.The algorithm of compensation was used in the module of the offset coefficient.It decreases the float calculat ing 2/3 when modifying the matrix of resistor;and the setting calculation progra ms were writed by the object-oriented language C++,it made full use of these co ncepts,such as encapsulation,class,inherit,polymorphism,etc.These methods also m ake the software credibility,conservation and repeat.
