摘要
对并联型有源电力滤波器系统的电路结构、控制方法、工作原理、系统特性进行了分析和探讨,并利用Matlab中的电力系统仿真工具箱对其进行了建模和仿真。并联型有源电力滤波器适用于多种负载条件下的谐波和无功补偿,尤其是能应用于电源电流畸变和不平衡条件下。稳态仿真结果表明,该方案具有很好的谐波补偿效果、并且具有通用性。有源电力滤波器是一种满足谐波标准要求、且能很好地解决谐波问题的装置。
The circuit structure, the control method, the work principle and the system characteristics of the shunt active power filter system are discussed and analyzed, which are built into models and simulated by the Power System Toolbox of Matlab. The SAPF prototype can compensate harmonics and reactive well under varies load conditions, especially in the case of a distorted or unbalanced current of power supply. Simulation experimental results show this scheme has perfect harmonics compensation performance and has generalization of the proposed method. Active Power Filter (APF) is being considered as a potential candidate for solving harmonic problems in order to meet harmonic standards and guidelines.
