油田电网节能降损优化研究

针对油田电网节能降损的要求,结合油田配电网的特征,计算了油田电网现有损耗值,从建立节能优化数学模型入手,采用分散补偿法和集中补偿法对油田电网无功补偿的最佳位置、最佳容量和变压器最佳分接头档位应用遗传算法进行了研究,编制了基于分散补偿法和遗传算法的油田电网无功优化软件.以塔河油田配电网为算例的计算结果表明:分散补偿法可确定补偿位置;遗传算法可确定变压器分接头档位,且在补偿容量和减少线损方面优越于分散补偿法.研究结果对油田采用何种节能措施具有参考价值.

Study of Energy Economization and Loss Reduction on Oil Field Power Network

In order to economize the energy and reduce the loss of the oil field power network,based on the characteristics of oil field power distribution network,the power loss value was calculated.By adding compensation capacitor and adjusting tap position of on-load tap changer,mathematical models for reactive power optimization were given,and by the method of dispersed compensation and centralized compensation,the optical position,capacity of compensation and the tap position of on-load tap changer were studied.The reactive power optimization software of oil field power distribution network was programmed.Calculation examples of TAHE oil field power distribution network showed that the genetic algorithm can be used to determine the tap position and is more suitable to the compensation capacity and the energy loss than the dispersed compensation method.The dispersed compensation method can be used to calculate the compensation capacitor position.
