超高压变电站启动向量测试方法及原理分析

Test Method and Principle Analysis of Startup Vector in EHV Substation

变电站新设备投入运行过程中,启动设备向量测试是直接判断一次设备运行状态、二次系统施工正确与否的重要手段。对向量测试结果进行分析并做出正确判断显得尤为重要。在东苏旗500 kV变电站新建工程的启动向量测试结果的基础上,结合安徽芜湖楚城500 kV变电站3号主变扩建工程向量测试数据结果和多年工作经验,完成典型向量模型搭建和分析,可作为后续启动向量测试的依据。

When the new substation equipment is put into operation,the equipment startup vector test is an important means to directly judge the operation state of the primary equipment and the correctness of the secondary system construction. How to analyze the vector test results and make a correct judgment is particularly important. On the basis of the start-up vector test results of 500 kV Dongsuqi Substation,this paper summarizes the results of 500 kV Chucheng variable vector test data,and combines the author’s many years’ working experience to complete the typical vector model construction and analysis,which is the basis for the subsequent start-up vector test.
