Designing of PMU Tester in Smart Substation Based on Test Method

Abstract

It lacks the effective ways to test the PMU in smart substation at present. The testing method based on distribution characteristics of acquisition unit and concentration unit of PMU in smart substations, is proposed to solve the situation of PMU of smart substation. Therefore, the PMU tester belonging to smart substation is designed based on the fundamental requirements of tester according to the methods proposed, and the vital points of designing are introduced and emphasized to tackle the reliability of PMU. The method and technology raised and the PMU tester designed in smart substation, in practical, could complete the test of accuracy of PMU, abbreviate the procedure of complicated data disposal and test report composing. It ensures to ameliorate the testing efficiency and validity on PMU of smart substation.
