Improving Energy Efficiency Of Power Grids In Industrial Enterprises

Since the reactive power transfer necessary for the operation of power equipment is one of the main components of the power supply network system loss,reducing reactive power consumption is an important research content in electric energy transmission.The energy consumption is mainly composed of the loss of transformer and grid line,and the reactive load of users.It can be seen that the reduction of energy consumption is achieved by improving the reactive power compensation.Therefore,the reliability of the operation of the reactive power compensation device is an important condition to ensure the reduction of power loss.Aiming at the power loss problem of 0.4-35 k V distribution network,this paper aims to establish a model structure of reactive power compensation by studying the automatic adjustment and optimization strategies of power equipment and systems to improve the energy-saving efficiency of the enterprise power grid.Therefore,the research plan of this paper is as follows: 1.Analyze the loss of power in the total system due to the transmission of reactive power in the power supply network;2.Based on the structural demonstration of each link of the system,the possibility of using cosine capacitor compensation in the automatic capacitor unit,And the effect of its switching method on the power quality in the compensation network;3.Study the input parameter detection principle of the automatic capacitive device reactive power regulator,and give design updates(compared to the typical architecture)to expand the function of the regulator;4 2.Consider the operation mode and load reactive power,and verify the effectiveness range of the user network 6k V/10 k V and 0.4k V network using capacitive device adjustment;4.Develop and verify the application of adjustable capacity in the grid of agricultural enterprises The technical and economic evaluation methods of sexual devices and their effectiveness.Based on the above scheme,the goal of this paper is to study the model of reactive power compensation device,apply the theoretical basis of power system analysis,systematically study the optimization method of reactive power compensation device parameters and its technical and economic calculation and evaluation methods to ensure the reduction of power distribution in agricultural enterprises Power loss in the network.
