继电保护课程设计可视化整定计算系统的开发与应用

Development and Application of Setting Calculation Visualization System in Course Design of Protective Relaying

为实现电网网架结构自主设计、设备及线路参数及时更新、相应计算自动执行等功能,该文设计和开发了一套继电保护课程设计可视化整定计算系统。该系统基于Matlab/GUI环境,通过调用PSAT、Simulink等模块,设计集成了绘图、运算、分析、可视化输出等功能。可随时增添数据与保存常用发电机与变压器、线路型号等参数,并以图形、表格、报表等方式外化运算结果,便于可视化分析与应用。教学实践证明该系统具备绘制电力网络及自动完成电力系统潮流计算、短路计算和整定计算的功能。

To design the power grid structure independently, update the equipment and transmission line parameters timely, and perform calculations automatically, this paper develops a setting calculation visualization system for the course design of protective relaying based on Matlab/GUI. By calling modules including PSAT and Simulink, the developed system integrates functions such as graphics, computation, analysis and output visualization. Generator, transformer and line parameters can be added at any time, and visual analysis and application can be implemented by externalized result with graphs, tables, reports, etc. Teaching practice proved that this system can achieve power grid drawing, and perform the calculations of power flow, short circuit and setting automatically.
