本文针对煤矿电网系统的特点,根据煤矿继电保护整定计算的实际情况,利用面向对象程序设计方法,采用C#编程语言和SQL数据库,实现了对整定计算整个软件的设计。构建了一套具有图形建模、故障计算、整定计算、定值仿真和数据管理功能的煤矿系统整定计算软件。该软件确保了煤矿电网故障计算值和保护整定值的正确性,提高了煤矿继电保护系统的运行管理水平。
In this paper, according to the characteristics of coal mine power system, according to the actual situation of setting calculation of relay protection in coal mines, the design of whole software for setting calculation is realized by object-oriented programming method and C # programming language and SQL database. A set of coal mine system tuning calculation software with graphic modeling, fault calculation, setting calculation, setting simulation and data management functions is constructed. The software ensures the correctness of the calculated value of the coal mine grid fault and the setting value of the protection and improves the operation and management level of the coal mine relay protection system.
