摘要
研究双电源的换位、不换位单回以及耦合双回线短路点定位的新方法,其特点为:①两侧之间工频量不必同步。②适于换位和不换位的长线。③线路分布电容、过渡阻抗和系统运行方式等因素对测距精度没有影响。大量的模拟故障测距数字仿真表明,本方法具有较高测距精度。
The paper describes new fault location algorithms for ( un ) transposed single - circuit line and for double - circuit line. The propose scheme has following improved aspects: ①The measurements takenat the two ends are not required to be synchronized.②The technique is suitablefor(un) transposition long line . ③The precision of locating fault is virtually independent of the shunt capacitance, fault tran-sient impedance and source impedance,etc. Results of transient performance of locating fault show that the presented technique is feasible.
