Abstract: Optimizing operation of oil field power network aims at tapping the potential of power supply to meet the demand of oil field operation. Two Schemes of automatic synchronous compensation and phase modulation were considered. The first scheme is a kind of local compensation, in which the synchronous motor functions both as a primer mover and a phase modulation machine. This scheme is recommended for oil field operation, in which water injection requires continuously operating large capacity induction motors. Experimental simulation and mathematical analysis for optimum compensation showed that the optimum operation of power network must be decided after an analysis of the overall benefits according to the quality of the load. For the same scheme, the optimum operation of the power network can only be obtained with the use of tracing control according to the operation state of the system.

摘要： 本文对油田电网实现优化运行的两种方案进行分析,从而提出各方案的适用条件。讨论了采用自动同步补偿方案的优越性,介绍了该方案的一套模拟实验装置。为建立电网各参数的函数关系进行了必要的数学推导。可以确认,油田电网优化运行方案的选取应按照负荷性质的不同进行综合效益分析,即使同一方案,也应按照系统运行状态的不同,借助跟踪调节技术,确保电网实现优化运行。
