| 摘 要： | 提出一种基于前馈解耦算法的单相电力弹簧功率控制策略，并以纯阻性负载为例，建立单相电力弹簧在不同坐标系下的数学模型。利用二阶广义积分发生器构建虚拟的正交电压和电流信号完成单相dq旋转坐标变换。针对单相电力弹簧自身结构的特殊性，提出在传统功率解耦控制双闭环的结构中引入额外的滤波电容电压内环，以达到对公共连接点输入有功功率和无功功率完全解耦的目的，并详细描述了电容电压内环的设计方法。最后，通过实验验证所提策略的有效性。

| Abstract: | The power control of single-phase electric spring(ES)based on feedforward decoupling algorithm is proposed. Taking the pure resistive load as an example, the mathematical models of single-phase ES in different coordinate systems are established. The second-order generalized integrator is introduced to construct the virtual quadrature voltage and current signals to complete the single-phase dq rotating coordinate transformation. Considering the particularity of the topology, an additional inner-loop for regulating filter capacitor voltage is added to the traditional power decoupling control using double closed loop to achieve the independent control of the active and reactive power injected to the common connection point(PCC). Besides, the design of the proposed inner-loop is illustrated in detail. Finally, the proposed power decoupling control method is verified by experimental results. |
