降低网损的无功补偿方案研究

Study on the Scheme of Reactive Power Compersation with Loss Reduced

减少电能在传输过程中的能量损耗是电网节能降耗的一个重要方面。电力系统中无功的分层平衡,有利于减少输电路径上无功的流动,降低电网传输损耗。阐述了在满足电网电压质量及投资经济性的基础上对上海电网分层、分区的无功平衡问题进行了研究,提出了各电压等级电网可采取的无功补偿策略。

Reducing energy loss in power transmission is an important ring of energy-saving and loss-reducing in power network. Balance of reactive power at different voltage levels is favorable for reducing the flow of reactive power and the loss in transmission. On the basis of satisfing voltage quality and investment economy, this paper studies the problem of reactive power balance at different voltage levels and districts in Shanghai Power Network, and oresents the trategy of reactive Dower comnersation which can be adopted.
