为了研究电缆在交叉互联接线时的绝缘在线监测方法,采用EMTP/ATP中的LCC模块进行建模,通过推导交叉互联电缆的分布参数方程,验证了此种接线方式的有效性.仿真结果表明,通过分析金属护层上的感应电压与接地电流可实时监测电缆的运行情况,并对主绝缘故障的发生位置进行初步判断.
Model Analysis and Calculation of Cross-linked Single-Core XLPE Cable
To investigate a new online insulation monitoring method of cross-linked XLPE power cable,this paper uses the LCC in EMTP/ATP to model on the cross-linked cable,derives the the distribution parameter equation for crosslinked cable,and thereby verifies the validity of this kind of connection mode.Simulation results show that the cable running status can be monitored in real time through analyzing the induced voltage on the metal sheath and grounding current,and preliminarily judging the location of major insulation fault.
