Embodiment Construction
[0040] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0041] figure 1 is the topology of the MMC-HVDC system, and its MMC-HVDC system sub-modules are figure 2 The full-bridge submodule shown.
[0042] The short-circuit fault of the present invention is a single-pole grounding short-circuit fault that only occurs in one of the positive and negative poles. The control method involves the control of the fault-located pole and the control of the other pole opposite to the fault-located pole. The specific implementation steps are as follows:
[0043] (A) Assuming that a single-pole grounding short-circuit fault occurs in the positive pole of the MMC-HVDC system, the positive pole is the pole where the fault is located, and the control steps for the positive pole are as follows:
[0044] A1) Use the voltage Hall sensor to collect the three-phase voltage signal u of the AC grid abc , sub-module capa...
