零无功滤波器的设计与工程应用

Design and Engineering Applications of Lower Reactive Power Output Filter

针对目前部分末端用户负荷功率因数较高,而谐波严重的情况,研究设计了一种新的电路,使滤波器运行时输出无功较小,对于特定的谐波其阻抗接近于零,因此达到滤波的目的,并将该技术首次应用于温州文成钢厂的实际工程中,效果良好。

For such situations as high power factor and serious harmonic to the partial terminal user,a new circuit is designed to achieve small output reactive power and, for specific harmonic, its impedance is close to zero and achieves the purpose of filtering. The technology is applied for the first time in the practical projects of Wenzhou Wencheng steel plant, and the application effect is good.
