基于Excel的变压器差动保护试验数据计算系统开发应用分析

摘要

差动保护是主变设备的主保护，其试验过程及数据的计算较为复杂，针对变压器差动保护试验数据的计算，利用Excel程序开发了一套试验数据计算系统，对于提高差动保护工作效率起到了一定的作用。%Differential protection is the main protection of main transformer equipment, the test process and the data calculation is relatively complex. Aimed at the calculation of transformer differential protection test data, a set of test data computing systems is developed by Excel program, it plays a certain role in improving the working efficiency of differential protection.
