0　引言近几年来 ,计算机监控系统在东北电网 50 0 k V超高压变电站中得到了广泛应用 ,投资规模也越来越大 ,但其应用并不理想。电力规划设计总院组织提出的《2 0 0 0年示范变电工程设计研究》对于常规控制方式与计算机控制方式进行了较为详细的分析比较 ,但如何优化变电站自动 0 Introduction In recent years, the computer monitoring system has been widely used in 50 0 k V EHV substations of the Northeast Power Grid, and the investment scale is also growing, but its application is not ideal. Power Planning and Design Institute organized by the “200 years of demonstration substation engineering design,” the conventional control methods and computer control methods conducted a more detailed analysis and comparison, but how to optimize the substation automatic
