| 摘要: |
| 针对大功率混合有源电力滤波器，为了有效降低有源部分的容量且提高补偿性能，首先对一种大容量混合有源滤波器进行改进。通过建立单相等效电路，对这种拓扑结构下的两种传统的电压源控制策略进行分析，在此基础上重点研究一种电压源复合控制策略。在分析了复合控制策略下的滤波原理后，对滤波器谐波检测方法、滤波延时的补偿进行研究，并设计出完整的复合控制策略电路结构。最后，对三种控制策略分别进行了仿真实验。通过对比补偿后的系统电流波形和补偿电流的动态跟踪特性，结果表明复合控制策略下的混合有源滤波器综合性能要优于传统电压源控制策略下混合有源滤波器性能，具有更强的实用性。 |

| Abstract: |
| For high-power hybrid active power filter, in order to effectively reduce the capacity of the active part and improve the performance of compensation, a new hybrid active power filter is improved firstly. By setting up single phase equivalent circuit, two kinds of traditional voltage-source control strategies are analyzed. On this basis, the paper focuses on studying a voltage-source compound control strategy. After analyzing the filtering principle of the compound control strategy, the paper researches the method of the harmonic detection, the compensation of the filtering delay, and designs a complete circuit structure of the compound control strategy. Finally, simulation experiments are carried out on three control strategies. The compensation current of the system and dynamic tracking performance of the current waveform are compared, the result shows that comprehensive performance of hybrid active filter based on the compound control strategy is superior to the traditional voltage source control strategy with more practicality. |
