Abstract:Research purposes: In order to improve power supply reliability, the 30 -60km long power cable through linewas used forShijiazhuang -Taiyuan PDL. Its capacitive currentwas normally bigger than 30A and exceeded the international limited value. Since the loadwas nothigh in the railway section, the loadmuch differed in different time and runningmethod, and the capacitive current of the cable line amounted a big proportion of the total curren,t the capacitive currentof the cable line changedwith the change of railway load. In order to solve the capacitive effec,t this paper analyzes and calculates the compensation capacitywithATP to determine the plan of compensation and extinction of the electrical arc.
Research conclusions:Combined with the actual engineering situation of Shijiazhuang -Taiyuan PDL, this paper describes the harm probably caused by capacitive effect of long cable line, gives the resolution to this problem, and determine compensation capacitiesof the static -type SVG and tracking-mode extinction coilwithATP. Thismethod is proved reliablewith perfect result in the real testand can be as the reference to the similarworks.
