摘要 为了有效地改善电网电流中因接入非线性负载所引入的谐波分量和削弱控制系统的延时特点,提出了一种基于预测函数模型的有源电力滤波器(APF)补偿电流控制方法,由当前时刻采样数据和最近历史时刻的数据进行构建预测函数模型,实现了有源滤波器谐波补偿电流的预测控制。仿真结果表明:该控制方法不仅对负载电流有精确的预测能力,且对系统电流中谐波电流具有较好的抑制效果和补偿精度。 In order to effectively compensate harmonics in grid current produced by non-linear loads and weaken the delay characteristic of the control system,a control strategy of current compensation about active power filter(APF) based on predictive function model is proposed. This control strategy is a way of predictive control. It uses the sampling data of current time and recently historic data to build predictive function model which is used to achieve predictive control of harmonic compensating current of active filter. Simulation results show that this method not only has accurate predictive ability for load current,but also has good suppression effect and compensation precision for harmonic current.
