摘　　要：针对传统人工线路保护整定计算方法工作量大、耗时长,存在人为错误的风险,无法满足配电网自动化线路三级开关保护整定需求的问题,提出在VS.2003集成开发环境下,利用VC++编程语言,基于MFC对话框编制整定计算程序,设计了一款能代替人工进行配电网线路保护整定计算的软件,实现了在一个计算界面内同时进行三级开关保护整定,并提供定值校验功能。最后结合工程实例分别进行人工计算和软件计算,结果显示,二者计算值完全吻合,验证了软件的正确性与有效性。The traditional method of manually calculating the line protection setting has the shortage of heavy workload,long time and the risk of making mistakes,which can no longer meet the current situation of the three-level switch protection setting of the distribution network automation line.In view of that,under the integrated development environment of VS.2003,VC++programming language is used based on the MFC dialog box to compile the setting calculation program,design a software that can replace manual distribution network line protection setting calculation,realize the setting of three-level switch protection in a computing interface at the same time,and provide the calibration function of setting value.Finally,the manual calculation and the software calculation are carried out with the engineering examples.The results show that the calculated values are in perfect agreement with each other,which verifies the correctness and effectiveness of the developed software.
