Abstract

In this paper

current injection method for noise test of capacitor based on cascade H-bridge circuit is proposed with combination of actual parameter of capacitor for HVDC power transmission and a kind of test system meeting the requirement simultaneously of noise test for such different types of capacitor products as AC filter capacitor

HV shunt capacitor and DC filter capacitor. The single-phase voltage source generator based on IGBT switching element is adopted for the power supply of noise test so to output separately and simultaneously fundamental current or random harmonic current combination from 1

2 kinds of frequency harmonics within 2

0 th harmonics. Both correctness and reliability of the test system is verified by the noise test of capacitor of PSCAD software simulation and under full power series and parallel mode of 70% test system

the audible noise of capacitor unit in the HVDC converter station is equivalently simulated. The test result fully complies with related specification in GB/T 32524-2016

which provides a kind of new test method for measuring the noise level of capacitor of HVDC transmission project and has stronger engineering instruction significance.
