近二、三十年来,由于大容量原子能电站和水电站的并网发电及超高压远距离输电系统的建成,国内外各主力油田变压等级的增加,使电网中无功功率消耗的比例日益增大。采取无功跟踪补偿及相关技术,实现电网优化运行,旨在降低网损、节约电能、挖掘发、供电的潜在容量,是当前各国油田电网发展的趋势。 In the past two or three decades, due to the grid-connected power generation of large-capacity nuclear power station and hydropower station and the construction of EHV long-distance transmission system, the transformation level of major oilfields at home and abroad has been increasing, resulting in a growing proportion of reactive power consumption in the power grid Big. Reactive tracking compensation and related technologies are adopted to realize optimal operation of power grids. The aim is to reduce the network loss, save energy, and excavate the potential capacity of power generation and distribution. This is the current trend of the development of power grids in various countries.
