辽河油田作为全国最大的稠油高凝油生产基地,主要电力负荷是抽油机和泵的电机,且主要以异步电动机为主,消耗大量的无功,因此必须合理进行无功补偿,并优化配置。辽河油田针对电网实际采用变电所集中补偿、配电线路分段固定补偿、低压配电间集中补偿及用电设备就地分散补偿四种方式,实现了无功优化补偿,改善了系统电能质量,取得了明显的经济效益。
Liaohe Oilfield is the largest production base of heavy oil with high pour point in China. The main electric load is the motor of pumping unit and pump. The main power of the Liaohe Oilfield is asynchronous motor, which consumes a large amount of reactive power. Therefore, the reactive power compensation must be reasonable and optimized Configuration. Liaohe Oilfield, the actual use of the grid substation centralized compensation, fixed fixed distribution lines, centralized distribution of low-voltage distribution and decentralized compensation for the use of electrical equipment in four ways to achieve reactive power compensation, improve the system power quality , Has made obvious economic benefits.
