【摘要】 通过研究低频交流注入法绝缘阻抗监测及故障定位系统原理,多电缆并联故障定位方法,评估供电系统及设备的安全情况,实现供电系统在线故障定位。采用理论模型计算、实际系统搭建、在线实测数据来验证原理与方法的可行性。通过供电系统在线实测数据可以看出,交流注入法在ITN船舶岸电供电系统中运行可靠,故障报警定位准确无误。
【Abstract】 In this paper, the principle of insulation impedance monitoring and fault location system and fault location method of multi-cable parallel connection are used estimate the safety status of the power supply system and ship equipment, and furthermore to accomplish on-line fault location. Theoretical model calculation, practical system construction and on-line measured data are combined to verify the feasibility of the principle and method. The on-line measurement data show that the AC injection method is reliable for the ITN ship shore power supply system and the fault location is accuracy.
