With the development of society and the advancement of science and technology,electricity is getting closer to people's lives.Due to its advantages such as mass production,convenient management,long transmission distance and environmental protection,electric power plays an irreplaceable role in people's life.Modern power systems are moving in the direction of UHV,large capacity and long distance.Under the influence of many factors,it is very important for the power grid to operate normally.Reactive power optimization means trying to make one or more performance indicators of the entire power grid reached the optimal solution of reactive power adjustment through the modification of some controllable variables in the distribution network,when the grid is given the distribution network topology and distribution network load situation,and is under the condition of some constraints in the distribution network.Reactive power optimization can effectively ensure the distribution network safe and economical operation,and can improve the voltage quality of the entire power system.The design and implementation of the web-based reactive power optimization process modeling tool provides users with a complete set of modeling process from the input of circuit editing topology to the display of reactive power optimization results.Compared with the existing reactive power optimization system,the system replaces the complex model configuration and data input with the editable layout of the circuit diagram through the web-side visual interface,and has a good interactive interface that the user can edit optimized logic circuit diagram in the interface.It makes up for the shortcomings of reactive power optimization that is too and difficult to read,so it's more easily accepted by users.At the same time,it provides a new method in reactive power optimization calculation to improve the speed and accuracy of reactive power optimization.In order to realize this reactive power optimization modeling tool,this paper first analyzes the relevant technologies required by the system implementation and analyzes the feasibility and difficulty of the system implementation.Then the demand of the system is analyzed.Through the analysis of the whole process of reactive power optimization modeling,the functional and non-functional requirements of the system are clarified.After that,the key problems to be solved in the process of system realization are analyzed and realized:In order to realize the binding mapping between user view and data model,the system proposes and implements the bidirectional data binding framework based on the life cycle hooks.In order to improve the speed and accuracy of reactive power optimization calculation,a reactive power optimization calculation method based on similarity matching is proposed in this paper,which carried out iterative calculation based on the historical scheme to improve the speed and accuracy of the calculation.After that,the overall design and implementation of modeling tools for reactive power optimization were completed,and the functions of modeling tools were tested and analyzed.Finally,the paper summarizes the work,points out the existing shortcomings of this modeling tool and the future direction of improvement and development.
