Abstract

The present invention discloses a system and a method for test of a master station and a substation of an intelligent transformer substation phasor measurement unit (PMU). The system comprises a PMU tester, a PC substation client and a PC master station client. The PC substation client controls the PMU tester to send a current and a voltage which have time marks to a PMU collection unit, the PMU collection unit centrally stores the current and the voltage in the PMU collection unit and then sends the current and the voltage to a dispatching master station; data in the PMU collection unit are transmitted back to the PMU tester after being processed by the PMU collection unit; the PC master station client analyzes current and voltage signals, uploaded to the master station, of a PUM device to form a master station data file; and master station data and substation data are correspondingly compared through analysis of the PMU tester to complete error calculation of the current and voltagedata. The technical problem of master station and substation joint debugging testing in a current intelligent transformer substation PMU device test is solved, and validity and dependability of the test of intelligent transformer substation phasor measurement unit are improved.

Description

technical field [0001] The invention relates to the field of WAMS (Wide Area Measurement System) application of dispatching master station and testing and research field of intelligent substation synchrophasor measurement device (PMU device), in particular, it relates to a master-substation test system and method of intelligent substation synchrophasor measurement device. Background technique [0002] The synchrophasor measurement function of the PMU device provides data source support for the WAMS application of the dispatching master station and the calculation and analysis of power grid security and stability, so it bears a major responsibility for the safety and stability of the power grid. In recent years, with the rapid development of smart substations, the testing of PMU devices in smart substations is urgently needed. At present, the test method of the PMU device in the smart substation is to control the PMU tester to send the voltage and current IEC61850-9-2 protoco...
