摘要
结合电力系统仿真技术的新发展,提出一种基于面向对象技术的变电站运行仿真分析系统的软件方案。系统运用Visual C++程序语言,采用可视化用户界面,运用动态链接库DLL(Dynamic Link Library)技术建立各种二次设备的模型库。论述了可视化图形编辑器、系统计算模块的实现(以潮流计算和故障计算为基础)、二次设备模型库的建立、模块间的数据通信/计算同步问题等技术。该软件可用于电气设备工作状态及系统运行情况分析、继电保护装置评估、继电保护动作逻辑仿真等。
Combined with the new achievements of power system simulation technology,a software design of substation operation simulation and analysis system is proposed based on the object-oriented technology,which establishes the library of various secondary equipment models utilizing the technologies of Visual C＋＋ programming language,visual user interface and DLL（Dynamic Link Library）. The key technologies are discussed,such as visual graphical editor,implementation of system calculation module（based on power flow calculation and fault calculation） ,establishment of secondary equipment model library, data communication and synchronous calculation among modules,and so on. It can be used in the analysis of electrical equipment working status and system operating conditions,the assessment of protective devices and the simulation of protection logic .
