摘要
为使有源电力滤波器(APF)直流侧电压顺利升至设定值并安全并网,介绍了采取软起动的必要性;同时分析了目前软起动的方法,并将其划分为3大类:外加电源法、外加限流电阻法、智能控制算法。最后,比较了每种起动方法的优缺点,为工程应用中选择合适的APF起动方法提供指导,避免出现重复起动、烧坏设备等情况,具有一定的实用价值。
This paper firstly introduced the necessity of adopting soft start to make the DC side voltage of APF rise to the setted value. Then,the method of soft start was analyzed, and it is divided into three categories： external power supply method, external current limiting resistance method and intelligent control algorithm, and each category has a fine classification. At last,the advantages and disadvantages of each method were compared,and it is helpful to select the suitable APF starting method in engineering application. It can avoid some situations such as repeated priming, burning equipments and has a practical value.
