Secondary Arc Current and Recovery Voltage of 1000 kV AC Compact Ti＇ansmission Line
摘要
Abstract
The characteristics of 1000 kV AC compact transmission line are discussed, and the calculating results of secondary arc current and recovery voltage of 1000 kV AC compact transmission line using EMTP under different conditions such as the different length of the transmission line, the compensation factor, transposition, are preSen- ted. Simulation results show that the neutral reactor for HV shunt reactors can effectively limit the second arc cur- rent and recovery voltage, and the principle of selection of neutral reactor must take both insulation level and re- straint of second arc current together with recovery voltage into consideration. It is required that the time of reclos- ing should be 0. 7 s, the length of compact transmission line be 100 km to 500 kin, and the degree of compensation be 95 %, instead of 70 %. However, the influence of transposition, compared with random factors such as environ- ment, or the cost of construction of transposition tower, is negligible. The transposition is not recommended for compact transmission line.关键词
