特高压输电线路的工频过电压研究
Research on Power Frequency Over-voltage in UHV Transmission Line
摘要
Abstract
The level of over-voltage has an effect on the equipment security in UHV transmission line, based on UHV transmission line project, in this paper applies the domestic and foreign research in UHV power frequency over-voltage. The capacity effect of unloaded line and single-phase grounding fault was investigated, the methods, which influence the over-voltage were simulated and compared by ATP-EMTP. The effect of power frequency over-voltage is analyzed when high voltage parallel reactor is installed different spot and base on installed the high voltage parallel reactor, the effect of single-phase grounding fault over-voltage when the line both side with MOA. Simulation results show that the power frequency over-voltage can be suppressed to 1.135p.u. when properly installing the high voltage parallel reactor on the line; single-phase grounding fault is 1.317p.u. respectively. When MOA are applied the line, the over-voltage can be suppressed to 1.045p.u..关键词
