| 摘 要： | 本文考虑到线路中由于超高压输电线路的潜供电弧燃烧时间长,如果不能及时熄灭,将造成单相自动重合闸失败,从而影响供电安全和系统稳定.为此本文首先通过电路理论推导出抑制潜供电流的并联电抗器中性点小电抗以及潜供电流的容性、感性以及总潜供电流计算公式,以便精确计算短距离单回输电线路的潜供电流.本文利用仿真软件Matlab仿真分析了线间距离以及不同的补偿方式对潜供电流的影响.

| Abstract: | The paper considers that the combustion time of secondary arcs in the extra-high voltage transmission lines is long,if these arcs can not be extinguished in time,the single-phase automatic reclosing would be failed;thus it has bad effect on the power supply security and system stability.Therefore,this article derives calculation formulas of inductance on neutral of shunt reactors which restrain secondary arc current and the calculation formulas of capacitance,inductance and total secondary arc current by us... |
