摘    要:为提高有源电力滤波器的控制策略水平,针对一般稳定性负载的电网谐波的重复周期性特点,应用基于PI型学习律的重复学习控制策略以增强系统的鲁棒性,同时提高系统的跟踪精度。在某厂谐波治理系统的设计中利用PSIM设计系统整体方案、控制策略以及进行仿真,同时与采用传统滞环控制的跟踪控制效果比较,仿真实验验证了该算法的有效性。

关 键 词:谐波  重复学习  控制策略  滞环控制  仿真结果

Abstract:During the past years,the intensive use of power electronic equipment has caused an increase of the harmonic disturbances in the power distribution systems.The control of AC power thyristors and other semiconductor switches is widely employed to feed electric power to electrical loads,such as the typical diode-dc capacitor front-end configuration.These nonlinear loads generate harmonic and reactive current,which leads to low power factor,low energy efficiency,high harmonic distortion of the utility lines and harmful disturbance to other appliances at the same time.To alleviate this problem,conventionally,passive LC filters and capacitors have been used to eliminate line current harmonics and to increase the power factor.However,Passive filters,in some practical applications,suffer form resonance problems and tuning problem due to component tolerances.Active power filter(APF) is the efficient way to suppress the harmonics,as well as compensate for reactive power.To suppress effectively harmonic,a kind of control strategy of APF is important.According to the characteristic of re-period of current harmonics in steady-load power system, an algorithm of PI-type repetitive study control is applied for hybrid active power filter,in the same time,a forgetting factor is used to enhance systemic robust,and a feed forward based learning law of fuzzy inference current error is imported to improve its tract precision under the optimal object.At the last, the simulation results show the control strategy is correct and reliable,which lays a foundation for extending the applications.
Keywords:harmonics  repetitive study  control strategy  hysteresis control  simulation results
