摘　　要：随着电网规模日益扩大,网络结构日趋复杂,系统的短路容量在不断变化,经常要重复进行短路电流计算和继电保护定值校核。发电厂中由于电气设备多,定值改变频繁,微机保护逐步更换,继电保护的整定计算工作更加复杂繁琐。所以,开发出系统性、通用性强的保护整定计算软件系统,以减少工程技术人员的大量重复劳动,使软件实用化,修改方便,容易维护。As the size of power grid growing, and its structure becoming more and more complex, system short circuit capacity is also varying constantly, requiring frequent short circuit current calculations and relay protection setting checks. Because of excessive electric equipment in a power plant, their settings are changed frequently, and computer protection devices are being replaced gradually, which make relay protection setting even more complicated. Therefore, it is necessary to develop a systematic and general protection setting calculation software to reduce repeat work loads on workers. And the software should be practical and easy to be modified and maintained.
