Description
技术领域technical field
本实用新型涉及一种电力系统的补偿装置，属于强电设备技术领域，尤其是指一种动态复合无功补偿装置。The utility model relates to a compensation device for an electric power system, which belongs to the technical field of strong electric equipment, in particular to a dynamic composite reactive power compensation device.
背景技术Background technique
对于输电线路或局部供电系统，在输送相等数额的有功功率的同时，还伴有相当数额的无功功率。若供电电压一定，当功率因数变低时，则电流增大，使线路损耗增加，降低供电系统的供电能力，及供电电压的质量，对系统将产生不利的影响。各级网络和配电设备都要消耗一定数量的无功功率，其中配电网消耗的无功功率所占比例最大。变电站的集中补偿主要是补偿变压器本身的无功损耗，以及减少变电站以上输电线路传输的无功功率，从而降低供电网络的无功损耗，但它不降低配电网络的无功损耗，用户需要的无功仍需要通过变电站以下的配电线路向负荷输送。For transmission lines or local power supply systems, while delivering an equal amount of active power, it is also accompanied by a considerable amount of reactive power. If the power supply voltage is constant, when the power factor becomes low, the current will increase, which will increase the line loss, reduce the power supply capacity of the power supply system, and the quality of the power supply voltage, which will have an adverse impact on the system. All levels of network and power distribution equipment consume a certain amount of reactive power, among which the reactive power consumed by the distribution network accounts for the largest proportion. The centralized compensation of the substation is mainly to compensate the reactive power loss of the transformer itself, and reduce the reactive power transmitted by the transmission line above the substation, thereby reducing the reactive power loss of the power supply network, but it does not reduce the reactive power loss of the power distribution network. Reactive power still needs to be transmitted to the load through the distribution line below the substation.
