采用逆阻型子模块的新型模块化多电平换流器
Novel Modular Multilevel Converter With Reverse Blocking Sub-modules
摘要
Abstract
Modular multilevel converter (MMC) is one of the promising voltage source converter topologies in the field of high voltage direct current (HVDC) transmission system. Based on analysis of the existing sub-module topologies, an improved half-bridge sub-module topology based on reverse blocking IGBTs (RB-HBSM) was proposed for solving the fault ride through issues. In this paper, the fault current blocking mechanism and the electrical stress of the main power switches were studied firstly in detail. Then the fault control flow chart was presented. Feasibility of the proposed sub-module topology and the fault protection theory were verified by simulation. The proposed RB-HBSM-MMC topology is able to block the fault current without changing the original control and modulation strategies compared with the conventional MMC, thus it further reduces the complicity of industry design.关键词
