摘要
针对一起配电线路断线故障,分析10 k V配电线路发生断线时的电压变化情况。通过分析不同情况下配电线路断线故障对电压的影响,得出该类故障发生时母线电压变化范围及规律。以某线路实际故障为例,确定断线部位,及时隔离故障,提高配网供电可靠性。
The change of voltage is analyzed when the 10 k V distribution line is broken according to one breakage fault of a distribution line.The change range and characteristics of busbar voltage are concluded for this kind of faults by analyzing the influence of the line breakage to the voltage.Taking an actual fault as an example, the position of line breakage is determined and the fault is isolated timely to improve the power supply reliability of the distribution network.
