摘要
针对网侧电压三相不平衡时电流负序分量使电流迅速增加进而危及系统安全的问题,提出电压三相不平衡时模块化多电平换流器(modular multilevel converter,简称MMC)型固态变压器的联合控制策略.在对电流正负序分量进行双序控制的基础上,设计了环流抑制器.仿真实验结果表明该联合策略具有有效性.
Aiming at the problem that the negative sequence component of current increased rapidly when the three-phase voltage was unbalanced on the grid side,which endangers the safety of the system,a joint control strategy of modular multilevel converter(MMC)type solid state transformer was proposed.On the basis of double-sequence control of positive and negative current sequence components,a circulation suppressor was designed.Simulation experiment results showed that the proposed strategy was effective.
