Optimization Research And Application Of Oilfield Power Grid Reactive Power Compensation

With the rapid development of China's economy, and change the pattern of global energy, energy saving has become an important force policy in many countries. For the power system and on the power grid reasonable for reactive power compensation can effectively reduce the energy loss, improve power quality, the reactive power compensation has become to improve power factor, reduce the power loss of an important means. Oilfield Power Grid has a certain particularity, in the power load in the inductive load ratio is relatively high, so the oilfield power grid has active power loss and power characteristics of poor quality. Therefore, oil and gas production enterprises and power supply enterprises how to improve power factor, reduce the power loss of oilfield power network, the oilfield power grid can be stable and reliable, safe and economic operation has become an urgent need to solve the problem. Based on this, this paper with the actual situation of the oilfield power grid based, to reactive power compensation theory as the support, in Daqing oil field power system as the research object, of oilfield power gird no configuration optimization and application of reactive power compensation launched a special study, through the construction of Oilfield Power Grid Reactive Compensation optimization case, achieve energy saving, improve the quality of power supply, improve power supply.Firstly, characteristics of oilfield power grid and power loss due to high rate of oil was analyzed, and the basic concepts of reactive power compensation of reactive power compensation and advantages, and the influence of the reactive power in the power system of oil field are discussed, the data model and the calculation method of power flow calculation of distribution network are introduced; then in the oilfield power grid reactive power compensation is based on the theory of optimal reactive power compensation model and the design of oilfield power grid, the model of objective function and constraint conditions are determined, and the introduction of differential evolution algorithm to optimize reactive power compensation based on a very wide range of applications in other areas, the basic principle and working process of the algorithm is discussed. The differential evolution algorithm in reactive power optimization process to start the design.To automatic calculation of reactive power compensation for Oilfield Power Grid Cut design of oilfield power grid optimization of reactive power compensation control system, the system integration model and algorithm design, can use the differential evolution calculation of reactive power compensation are automatically calculated by the communication scheme can be switched control instructions issued to the measurement and control device for automatic switching in design in the process of system structure, system controller, controller and communication system from the system detailed design scheme; finally, oilfield power grid will design the optimal reactive power compensation control system applied to celebrate the new change of Daqing oil field, the construction of the Qing Xin optimal reactive power compensation control system, at the same time, through the test of optimization of reactive power compensation the control system is analyzed to reduce the network power loss and application effect of improving power quality. Through the test and analysis of historical data found that the optimal reactive power compensation control scheme can effectively reduce the loss and improve the voltage quality of the oilfield power grid design, and achieved good economic benefits.
