低压配电网三相不平衡下的DSTATCOM优化控制
Optimization Control for DSTATCOM in Low-voltage Three-phase Unbalance Distribution Network
摘要
Abstract
The power quality problem of active and reactive power is caused by the negative sequence and zero sequence components as well as harmonics in the three-phase unbalanced low voltage grid. In order to suppress the harmonics better, the method of optimization control for DSTATCOM in low-voltage three-phase unbalance distribution network is proposed: use the PR control current loop, we can directly track the amount of sine adjustment. The control system can save a lot of Park transformation, and avoid the decoupling control. The simulation results show PR control can achieve the same compensation with the PI control in a shorter period. The feasibility and effectiveness of control method is verified.关键词
