摘　　要：介绍了ＷＸＨ─１５型微机线路保护面板和功能，根据其距离保护的工作原理，导出了距离保护的数学模型及动作判据。应用ＳＴＡＲ—９０仿真系统支持下的模块化的建模方法，开发了距离算法和保护装置算法，在此基础上实现了距离保护的仿真。应用结果表明，该仿真模型及算法在建模时简单实用，能满足仿真培训要求。In this paper, the control panel and function of the WXH - 15 line protector are introduced. The mathematics model and activating condition are deduced from the principle of the line distance relay. By means of the block modeling method supported by Star - 90 Software system, a distance relay algorithm and a protection algorithm are developed, and then the simulation of the line distance relay is realized. The results show that the method to simulate the line protection is simple and useful for the training simulator.
