Research On The Technology Of Reactive Power Compensation Optimization In Liaoyuan Urban Distribution Network

Reactive power compensation is a method of improving power factor of power grid to reduce power loss of transformer and transmission process,and then improve the environment of power grid,improve the quality of power grid and power supply efficiency.It is widely used in power system.In this paper,Liaoyuan urban distribution network as the research object,combined with the actual situation of Liaoyuan,Liaoyuan is located in the middle and south of Jilin Province,located in the upper reaches of the East Liaohe River and the UFA River,relying on powerful geographical advantages,to become a power intensive area,so how to optimize the optimization of reactive compensation in accordance with the development characteristics and environmental factors in Liaoyuan area The case is an important issue to be solved urgently.This paper introduces the research background and research significance of reactive power optimization optimization algorithm,and then introduces and analyzes the application scope and advantages and disadvantages of various power flow calculation algorithms,reactive optimization devices,reactive optimization algorithms and heuristic algorithms,which are related to reactive power optimization in distribution network.This paper introduces the theoretical basis of reactive power compensation in the distribution system,including the theoretical basis of reactive compensation,the theoretical basis of reactive compensation device and the theoretical basis of the heuristic algorithm,which are the three parts.Then,combining the special situation of Liaoyuan urban distribution network,this paper makes use of the natural network structure of distribution network in the process of distribution network power flow calculation,abstracts the distribution network into a constrained network,creates the node object and network connection,so as to facilitate the calculation of the parameters of the constrained network.At the same time,according to the structure characteristics of the constrained network,the dynamic heuristic is added to the node instantiation order in the process of constraint propagation to improve the efficiency of the distribution network.Finally,in this paper,a reactive power compensation optimization program based on dynamic heuristic is written in the C++ language,and the reactive power optimization of multiple lines in the actual power grid in Liaoyuan is calculated.The optimal allocation of reactive compensation points and compensation is obtained,and good economic benefits are obtained.It is proved that the heuristic based on this paper is proposed.The effectiveness of the reactive power compensation method.
