Research On The Path Optimization Method Of Helicopter Power Operation

With the rapid development of China's economy,the increase of national power consumption and the rapid growth of the complexity of power grid,the demand for power grid inspection is also increasing.However,the development foundation of general aviation is weak,the development structure is unbalanced,mismatched and uncoordinated,and the development power needs to be strengthened urgently,which has become the main problem restricting the development of general aviation electric power inspection.Therefore,how to optimize the path of helicopter power wire patrolling under the limited resources to improve the ability and service quality of power wire patrolling is the key problem to be solved.Based on the statistics and analysis of the historical flight data of helicopter electric patrolling inspection,it is found that establishing a practical helicopter electric patrolling inspection model is an effective way to optimize the route of patrolling inspection.In order to solve the problem of path optimization of helicopter power inspection,this paper starts with the historical helicopter flight data of different dimensions,and through the analysis of the historical flight data,it is found that the airworthiness conditions of the helicopter have obvious terrain,time and many other constraints.According to the similarity of the maximum mileage and undirected graph of the helicopter's daily patrolling,the helicopter electric patrolling model based on single alternate point and multiple alternate points is established respectively.The model can accurately describe the patrolling path of the helicopter to the high-voltage power grid in the mission area.Secondly,based on the analysis of the process of electric power patrolling inspection,the optimal time and region of helicopter patrolling inspection are considered according to the characteristics of the aircraft and the analysis of time and space dimensions.Finally,according to the depth first search and the minimum spanning tree method,the optimal path of helicopter electric power inspection is solved under the condition of limited daily patrolling mileage,single alternate point and multiple alternate points.Taking the actual situation of helicopter electric patrolling inspection as the historical flight data,the simulation results are compared with the actual situation through the simulation of the actual data,this method systematically analyzes the path optimization of the helicopter power inspection,to some extent,reflects the actual path of the power inspection.The research results provide theoretical support for the analysis of helicopter electric patrolling flight data,and provide decision-making basis for the actual electric patrolling path optimization,which has certain theoretical and application value.
