摘　　要：提出数字化变电站继电保护动作全过程仿真的总体方案,采用M、N 2台微机构建局域网,分别模拟数字化变电站的一次、二次设备的动作行为,并基于IEC 61850通信协议交换电流、电压波形数据和保护动作结果。在微机M中通过PSCAD/EMTDC软件开发自定义模块调用Winpcap,实现对IEC 61850数据包的发送和接收;微机N对相量进行提取,模拟继电保护判据的动作行为,并将保护动作结果返回微机M,以改进电力系统的运行方式。依据所提方案开发动作全过程仿真系统,在微机M中的PSCAD/EMTDC软件内搭建含220kV变电站主接线的电力系统仿真模型,故障仿真结果验证了该系统功能的完备性和性能的优越性。The whole protective relay process simulation system for digital substation was presented this paper. A local area network was established by microcomputer M and N, to simulate the primary equipment and the secondary equipment of the digital substation. Based on IEC 61850 communication protocols, the voltage, the current waveforms and the results of protective relay action can be exchanged between M and N. Through development user--defined module in PSCAD/EMTDC to call Winpcap in M, IEC 61850 data packets can be sent and received. The N is used to extract vector for relay protection. Thus, the action behavior of protection criterion is simulated by N, and the results is sent to M so as to change the operation mode of power system. A 220 kV substation simulation model is established in PSCAD/EMTDC, and the simulation results show that the proposed simulation system has perfect function and good performance.
