Title:
DEVICE FOR TESTING VALVE PERFORMANCE OF MMC-BASED HVDC AND MVDC SYSTEMS, AND TESTING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/139433
Kind Code:
A1
Abstract:
The disclosure relates to a device for testing valve performance of MMC-based HVDC and MVDC systems and a testing method therefor. The present embodiments provide a valve performance testing device and a testing method using same, the device and method in which, in securing the reliability of MMC-based HVDC and MVDC systems, a current for a valve performance test is generated on the basis of a direct-current power source voltage lower than the voltage of a sub-module capacitor, by using an auxiliary valve comprising the same number of sub-modules as a plurality of sub-modules (SMs) included in a main valve to be tested, thereby supplying a current similar to the current of actual HVDC and MVDC systems to the valve on the basis of a notably low capacity.
