摘　　要：为降低滤波系统和电网的参数变化对单独注入式有源电力滤波器(hybrid active power filter with single injection branch,SIBAPF)滤波性能的影响,提出了SIBAPF的模型参考自适应控制策略。建立了SIBAPF数学模型,并根据该模型建立了滤波系统参数自适应律。仿真结果表明,模型参考自适应控制方法较非线性PI控制方法滤波控制效果更好。基于该方法研制了SIBAPF试验样机,该样机投运后滤波效果良好,满足系统运行要求。To reduce the affects of parameter variation of filtering system and power grid on filtering performance of hybrid active power filter with single injection branch （SIBAPF）, a model referenced adaptive control （MRAC） straegy based on SIBAPF is proposed and a mathematical model of SIBAPF is built, and based on this model the adaptive law of parameters of filtering system is obtained. Simulation results show that by use of SIBAPF-based MRAC method a better control effect can be obtained than by nonlinear PI control method. Based on the proposed control method a experimental prototype of SIBAPF is developed. Operation experience indicates that the filtering effect of this prototype is satisfied and can meet the demand of system operation.
