Research On Energy Saving Technology Of Distribution Network

With the rapid development of global technology and economy,energy consumption is increasing.Energy scarcity has become the primary problem in the world.As the largest developing country in the world,with the rapid development of national economy,China has become the second largest energy consumer in the world,and the demand for energy is increasing.This phenomenon leads to the imbalance of energy supply and demand and the contradiction between environmental protection and economic development.Therefore,energy saving is a consideration that needs to be put in the forefront in the current development of various fields.Power grid is the main carrier of power transmission.No matter in power generation or power transmission and distribution,we should try our best to save energy and reduce losses.The situation of power grid in China is more complicated than that in foreign countries.As a power enterprise,energy saving and consumption reduction should be taken as the development goal of the enterprise,which is also the social responsibility that the enterprise must bear.Because of the above reasons,the work of energy saving and loss reduction of distribution network is urgent.This paper studies the energy-saving technology of distribution network,mainly from the following three aspects: first,the energy-saving and optimization of distribution transformer,analysis of the loss and loss reduction measures of distribution transformer,advocate the replacement of new energy-saving transformer,prove the advantages of energy-saving transformer with practical cases;second,the optimization and transformation of distribution line,analysis of the current way and advantages of energy-saving and loss reduction of distribution line Third,the concept of load node voltage stability margin is introduced to optimize the reactive power compensation of distribution network,which is calculated by power flow calculation to determine the position of reactive power compensation point;genetic algorithm is introduced to build the corresponding objective function,and the capacity of reactive power compensation is obtained in the optimization process.This method is appliedto practical cases for analysis.
