Research On The Reliability Of Highway Tunnel Power Supply System

The role of the highway tunnel power supply system is supplying and receivingelectric power for the mechanical and electrical equipments in the tunnel, and it is animportant component of the highway tunnel electromechanical system. The highway tunnelmechanical and electrical equipment is necessary facility in the operation of the highwaytunnel, so the reliability of the power supply system is placed in a crucial position, theoperation with high security and reliability not only can guarantee the efficiency of vehicletraffic in the tunnel, but also to ensure that the tunnel operator safety. Therefore, thereliability of the power supply system of the highway tunnel should be researched in system,and it predict the reliability indicators highway tunnel power supply system by establishinga scientific mathematical model of highway tunnel power supply system, so it can providean useful reference to the design and maintenance of the power supply system, thusensuring the safe and reliable operation of the highway tunnel.In this paper, the whole idea of the highway tunnel power supply system reliability isput forward by learning the current situation and the inadequacy of the current domestic andinternational research on reliability study of highway tunnel power supply system. Theoverall design method of the prediction of highway tunnel power supply system reliabilityis given by combining with the specific needs of the research projects. It discusses the keytechnologies involved in the calculation process, and a scientific and effective mathematicalmodeling method is given. It made a10KV tunnel power supply system reliability growthmodel and fitting inspection to determine the prediction of the reliability growth model ofthe highway tunnel power supply system is effective.In this paper, a method of analysis and assessment of highway tunnel power supplysystem reliability is given.
