چکیده
When the Modular Multilevel Converter (MMC) fails on AC side, operating characteristics of MMC will be damaged. If system wants to retain stable for a long time in process operation, it is obliged design control strategy case asymmetric fault. In this article, based feedback linearization principle adopted diminish negative sequence current caused by breakdown, and DC voltage controller devised suppress fluctuation double frequency component under fault conditions. The validity requires verified, running results PSCAD platform indicate method effective feasible.

Most of the wind power plants currently installed at North Sea are near to shore connected with the onshore grid through AC cable. AC transmission technology is proven and reliable, but there will be a need to switch from AC to DC transmission since large number of offshore power plants at longer distance to shore are expected to be installed by the end of 2020. Furthermore, to enhance the inte...
