Research On Optimization Of Electrical Pipeline In Building Based On Gravity Location Center Method

The optimal configuration of building electrical pipelines is one of the important measures for energy conservation and consumption reduction in the field of building electrical designing,and it is also a hot spot of current research.With the increase of electricity load and the increase of users’ requirements for convenience of electricity consumption,the complexity of electrical designing has increased.Based on the calculation of the distribution system load,the load moment center of gravity method is combined with the location selection of the distribution box in building electrical by calculating the equivalent load moment and equivalent load moment.Determine the location of the distribution power supply in the building,form an undirected graph between the power point and the load point,and extract the equipment information in the CAD to form a database.AutoCAD and MATLAB are used for joint simulation,the UP program was written and the shortest path is used to seek the optimal design of building electrical pipeline.Using MATLAB simulation software to complete the Dijkstra algorithm to solve the shortest path,through the MATLAB and CAD interface file,the shortest path results are fed back to the CAD electrical plan design to obtain the optimal design of the shortest path of the electrical pipeline.Using multi-objective optimization theory,the shortest distance and the equivalent distance are respectively applied to the physical center method,the traditional center of gravity method,and the equivalent center of gravity method.In the physical center method,the location of the power supply is more reasonable,and the shortest distance solution is more reasonable than the equivalent distance solution.Through the introduction of national designing code,IEC code and the joint simulation technology of AutoCAD and MATLAB,the study on the optimal layout of architectural electrical pipelines is completed,which can provide new ideas and effective methods for architectural electrical engineering design.
