| The distribution system is an important link of power system and power users in which there are some problems such as large network loss,unbalanced load,and low supply voltage and so on.With the rapid increase in electricity load and the safety and reliability of the increasingly high demand of users,the requirements of the distribution network optimization are proposed to solve the economic,security and reliability problems.Through the distribution network reconfiguration,we don’t need a lot of investment and can improve the safety and economy of the distribution network,using sectionalizing switches and tie switches to change the network topology configuration in the network.So the distribution network reconfiguration is an important means of distribution network optimization.The development of distribution network automation makes the implementation and evaluation of distribution network reconfiguration be possible.In order to make the dispatch staff to the application of reconstruction technique is simple and convenient,we must develop a software using visualization technology combined with reconstruction technology.Through the distribution network reconfiguration software,we can get the optimal method for distribution network reconfiguration,and provide an important reference for the power company network adjustment which has great significance in improving the economy,reliability and safety.This paper briefly introduces the development status of the development of distribution network reconstruction system and the importance of distribution network reconfiguration technology.On this basis,it introduces the power flow calculation method and the mathematical model and the implementation method of distribution network reconfiguration,describes the technology which is used in the development process of distribution network reconfiguration system software(including the development process of the software,the development method of the visualization software and MATLAB/GUI application development tools)and introduces the construction of ideas,principles,basic structure and function setting of distribution network reconfiguration system.The design and implementation of the specific function of the system are introduced and the software of distribution network reconfiguration is developed.The system includes the login interface,the main interface,the interface of network evaluation,the interface of network reconfiguration and the interface showing the answer of the network reconfiguration.It has the function such as hiding the login password,setting the basic data distribution network,importing basic information file,setting the switch position and evaluating the network,selecting the network reconfiguration algorithm and objective function and reconfiguring the network,and showing the results of network reconstruction.The system has open source code,strong expansion,modern design,reliable operation,easy operation etc. |
