摘要

提出了一种在abc坐标系下采用数字电流控制策略的三相D-STATCOM。该方案不使用锁相环，通过控制D-STATCOM的输出电流将无功功率传输到电网。电流控制器有一个零极和两个极。这种类型的控制器也被称为2型控制器。说明了控制器调优的步骤。采用保守功率理论(CPT)计算负载的无功功率。一个案例研究显示了D-STACOM在初始化、负载转换和稳态条件下的行为。实验结果表明了D-STATCOM的有效性。

Three-Phase D-STATCOM with Digital Current Control Strategy in abc-Reference Frame

This paper proposes a Three-phase D-STATCOM with digital current control strategy in abc- reference frame. The proposal D-STATCOM does not use a PLL and the reactive power is transferred to the grid through controlling the D-STATCOM output current. The current controller has one zero and two poles. This type of controller is also known as Type-2 controller. The procedure to tune the controller is explained. The Conservative Power Theory (CPT) is used to compute the reactive power of the loads. A case study shows the behavior of the D-STACOM during initialization, during load transitions and during steady-state conditions. The results show the efficacy of the proposed D-STATCOM.
