Abstract
According to DC voltage of cascade D-STATCOM affected by many facts and hard to control, a hierarchical coordinated control strategy of DC voltage is proposed in this paper.In order to make DC voltage more stable and con-trollable, stability control, phase control and balancing control are used separately for DC voltage total stability, phase-to-phase balance and modular balance.The simulation of PSCAD/EMTDC model under load change and unbal-ance load verifies the feasibility and effectiveness of the proposed strategy.关键词
