无源及有源滤波装置在污水处理中的应用研究

Study on Application of Reactive and Active Power Filters in Sewage Disposal

针对污水处理用电系统中非线性负载的特性及其危害,分析比较了无源滤波方案和有源滤波方案的原理及特点,从经济性和实用性两方面考虑,提出了无源滤波和有源滤波相结合的滤波方案。实际运行结果表明,该方案能有效解决污水处理厂的谐波危害问题。

In light of the characteristics and harm of nonlinear load in power system for sewage disposal, the principles and features of reactive filtering and active filtering schemes are analyzed and compared. A filtering scheme combining reactive and active filtering is presented in consideration of economic efficiency and practicality. Practical operation results show that the harmonic hazard problem of sewage disposal plant can be solved effectively by the scheme.
