Insulator flashover is a great threat of power system's safe and stable operation and surface discharge detection of contaminated insulators is an effective approach of flashover warning. Surface discharge detection method of contaminated insulators based on ultraviolet images' parameters is proposed in this paper. Experiment system of contaminated insulators surface discharge is designed to acquire...
Post insulator is one important part of outdoor vacuum circuit breaker's insulation, and surface discharge of post insulator is a main cause of outdoor vacuum circuit breaker insulation faults. A new method is introduced to detect surface discharge, using ultraviolet imaging technology. The images of post insulator's surface discharge are captured with ultraviolet imager. Meanwhile its discharge quantity...
A fuzzy optimization model based tolerance approach is proposed to handle timetable rescheduling in high speed railway during speed restriction period. As the limited speed and headway time are not crisp figures in practice especially when some natural hazards happen or some equipment failure, tolerance approach is introduced with the fuzzy membership functions of the original objective and soft constraints...
Our research is focused on cost evaluation of path planning with span through experiment and theoretical analysis. The evaluating plan is advised by combining safety, energy consumption and time consumption together and the optimal path is found from several paths. Based on the planning paths with search arithmetic, the cost evaluation of path planning with span researches the span of planet detector...
