模块化多电平换流器快速停机控制策略研究
A fast shutdown control strategy based on modular multilevel converter
摘要
Abstract
Firstly, this paper analyses the control strategies adopted by MMC in shutdown procedure and makes the energy saved in the capacitors feed back to grid as far as possible after considering the redundant sub-modules in each arm.Secondly, this paper deduces some formulas again to choose the system parameters and calculates the time of fast shutdown strategy to determine the the discharge resistance more reasonable.Therefore, a novel shutdown strategy with discharge resistance more reasonable as far as possible to reduce shutdown time and enhance economy of MMC system is put forward.Finally, a shutdown simulation model of MMC is constructed in MATLAB, which has more su-periority over other references published before.关键词
