煤矿实用混合有源电力滤波装置的设计

Design of Utility Filtering Device for Hybrid Active Power in Mine

针对大型供配电站需要在滤除谐波的同时进行无功补偿的工程要求,提出了一套较为实用的并联混合型有源电力滤波器的拓扑结构。以某煤矿110kV变电站主变压器低压侧10kV配电网的谐波治理及无功补偿为对象,介绍了滤波器无源和有源部分的设计过程。实际运行结果表明,能满足现场的需要。

For the engineering requirements of large-scale power distribution stations to filter out the harmonic and to go on reactive power compensation at the same time, the topology structure of a practical parallel utility filter device for hybrid active power is proposed. The design process of passive and active parts of a filter is introduced. It is aimed at the harmonic governance and reactive power compensation of the 10kV distribution network on the low pressure side of 110kV main transformer substations in a coal mine. The actual operating result shows that it can meet the needs of the site.
