Description

technical field [0001] The present invention is a system and method for performing a closed-loop test on a modular multi-level (MMC) flexible DC control device, especially a method for performing a real-time digital closed-loop test on an MMC flexible DC control device based on an RTDS (real-time digital simulator) The system and the method belong to the transformation technology of the system and the method for the closed-loop test of the MMC flexible DC control device. Background technique [0002] Modular multilevel (MMC) flexible DC transmission technology is one of the key and difficult points in the field of high-power power electronics research at home and abroad. It adopts controllable shutdown power electronic devices, which can not only realize the independent control of active power and reactive power, but also supply power to passive systems. When the power flow is reversed, the direction of the DC current is reversed while the polarity of the DC voltage remains...
