摘　　要：将无源滤波器和有源滤波器组合起来的混合型滤波器综合了有源和无源滤波器的优势,对电力系统的性能的提高具有更好的作用。目前市场的混合型有源滤波器主要是针对不同工况环境条件单独进行设计的,因此其无源滤波和无功补偿部分的硬件都是针对一种谐波滤波电路进行设计的,设计单一,不能对变化的电网情况进行变化。在实际的电网系统中,同一个电网,在不同的用电情况下,电网的谐波和无功情况是不同的,所以该文提出了一种综合性的无源滤波器的设计方式。采用可控晶闸管作为控制电容器和电抗器的开关,可以将电容器和电抗器进行不同组合。在用电单位发生变化的时候,可以根据监测的信号的特性进行分析和计算,总结出最优的滤波组合,使控制效果达到最优。通过模拟实验进行验证,输入不同的模拟信号进行采样信号分析,系统对不同的信号源做出了不同的控制策略,其结果是可靠的令人满意的。The reactive power compensator maked up of TSF and APF had the both finequality and had more power to the power systems qualities.But,at the moment,the compensators most were designed to the special sitution,so the design of filters hardware were single and couldn＇ t change with the current changes. In the electricity current, the systems＇ harmonics and reactive power always changed with the changing of electronic devices following the time changing. So, in this paper, a integrated design was come out.It can make up different combination of capacitors and reactors with the GTO/IGBT as the tap to control the capacitors and reactors to be on and off. When the electronic devices had changed,the syetems maked analysis and computation and give out the optimal combination making the controlling optimal. At last, the simulation test compared the analysis of different signal input and decined which were the best filters.The test results told the design was satisfactory and practical.
