配电网4种无功补偿方式的比较

电力系统中的电压与无功功率的状况密切相关,电力系统中无功功率的变化,会使各节点电压发生变化,并引起电力线路和变压器的损耗发生变化。当前电力系统装机容量的日益递增,电网建设尤其是配电网络的建设显得明显滞后,致使35kV及以下配电网的损耗问题日益突出。合理的选择无功补偿方式和补偿装置,能有效改善系统的电压质量,提高发、变电设备的利用率,降低网损。经济效益和社会效益极其可观。

Comparison of 4 kinds of reactive power compensation modes in distribution network

The voltage in power system is closely related to the situation of reactive power compensation,the change of reactive power makes the change of nodal voltage,also lead to the loss change of electric power line and transformer. At present,the installed power capacity of power system is increasing,the power grid construction,especially distribution network construction obviously lag behind,causes the loss problems of 35kV and below distribution network. So rationally choosing the modes and installations of reactive power compensation can effectively improve voltage quality and utilization ratio of generating and transforming equipment,reduces the loss of power network.
