Abstract

The invention discloses a testing system of a unified power quality controller and a testing method of the testing system. The testing system comprises an electric current perturbation generation device, a voltage disturbance generation device and a power quality monitoring system, wherein the current perturbation generation device is connected at the load side of the unified power quality controller in parallel, the wire outlet terminal of the voltage disturbance generation device is connected with the wire incoming terminal of the unified power quality controller, the wire incoming terminal of the voltage disturbance generation device is connected with the power supply of the system, the two ends of the current perturbation generation device and two ends of the voltage disturbance generation device are connected with the power quality monitoring system respectively. According to the testing system and the testing method, various working conditions of the unified power quality controller in practical application can be simulated, the power quality control function and the power quality control performance can be monitored and analyzed in real time, therefore, the purpose of comprehensively testing and analyzing the unified power quality controller can be achieved.

Description

technical field [0001] The invention relates to flexible AC power transmission and distribution technology, in particular to a test system and a test method for a unified power quality controller. Background technique [0002] The research on power quality control technology has huge economic and social benefits, and is a hot spot in the field of electric power research. Modern industrial, commercial and residential electrical equipment, such as high-performance office equipment, precision experimental instruments, frequency conversion speed control equipment, programmable logic controllers, various automatic production lines, and computer systems, are increasingly sensitive to changes in power characteristics. The requirements for power quality are constantly increasing. [0003] At present, the power quality controllers that have been widely studied mainly include: reactive power compensation devices (SVC and STATCOM, etc.), active power filters (APF), dynamic voltage res...
