污水泵站无功就地补偿技术分析与实践

Technical Analysis & Practice of Local Reactive Power Compensation in Sewage Pumping Station

无功功率补偿是污水泵站减少无功损耗和节能的有效技术措施。结合黄石市磁湖污水处理工程建设和运行实践,分析了目前污水泵站水泵电机无功功率补偿存在的问题,阐述了无功就地补偿原理和补偿方式的选择,在无功补偿量计算、电压选择、谐波共振、过载保护等方面,提出了无功就地补偿装置应用过程中应注意的技术问题,并取得了良好的经济效益和社会效益。

Reactive power compensation is an effective technical measure to reduce the energe loss in sewage pumping station. Combining Huangshi Ci Lake Sewage Treatment Project,this paper analyzed the problem existing in the pump motor reative power compensation, and expounded the principle of local reactive power compensation. The technical issues should be noted in the application of local reactive compensation were put forward ,and the good economic and social benefits have been achieved.
