交流1000kV与500kV/220kV同塔四回线路的潜供电流问题研究
Study on Secondary Arc Current of Four-circuit on the Same Tower Lines of AC 1000 kV and 500 kV/220 kV
摘要
Abstract
For four-circuit transmission lines with mixed voltages on the same tower,the electromagnetic interaction between lines is stronger and makes the problem of the secondary arc current complicated.To solve it,the mechanism of the secondary arc current has been discussed,a hybrid tower model that consist of double-circuit 1 000 kV lines and double-circuit 500 kV or 220 kV lines has been built in the electromagnetic transient program ATP-EMTP and the secondary arc current and recovery voltage of different voltage lines under different operation modes has been calculated.The results indicate that 500 kV or 220 kV lines have little influence on 1 000 kV lines while the 1 000 kV lines affect the 500 kV or 220 kV lines a lot.Furthermore,this study presents the recomm-ended single-phase reclosing time of different voltages and it can be reference for the design and construction.关键词
