Automatic detection system and method for new energy AGC or AVC control system

Abstract

The invention discloses an automatic detection system and method for a new energy AGC or AVC control system. The detection method comprises steps that (1), a device model of a new energy power stationis modeled, and initial state parameter values of new energy power station devices are set; (2), an active or reactive target value is issued by a main station simulation end to a detected system according to the target value information notified by an automatic test end through a com interface; (3), an instruction is received by the detected system, after calculation, remote adjustment or remotecontrol instructions are transmitted to all the devices in the simulation end of the new energy power station; (4), values of parameters of each device needing adjusted according to the instructionsare adjusted according to the received instructions and the initial state by the simulation end of the new energy power station, the result is fed back to the detected system, and the automatic test end is further informed; and (5), feedback result data of the simulation end of the new energy power station is received by the automatic test end and is written into a test report. The detection method is advantaged in that the closed loop simulation test of the detected system is performed, test complexity is reduced, and test efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of operation and maintenance of smart grids, and in particular relates to an automatic detection system and method for a new energy AGC or AVC control system. Background technique [0002] The vigorous development of new energy power generation has brought unprecedented development opportunities. In recent years, a large number of centralized and distributed new energy power stations have been connected to the power grid, which has a certain impact on the stable operation of the power grid and power quality. The resulting new energy power station AGC (automatic generation control) / AVC (automatic voltage Control) There are more and more control management systems, and many power manufacturers have developed their own control systems. Accordingly, power supply companies in provinces and cities such as Zhejiang, Anhui, Shanxi, and Guangzhou put forward requirements for network access testing of new energy AG...
