摘　　要：空间太阳能电站处在特殊的等离子体环境中,其能量转换与传输系统的绝缘有其特殊性,如何模拟太空环境中电气设备外绝缘局部放电及其有效监测方法,是空间太阳能电站可靠运行的关键技术之一。对空间太阳能电站能量转换系统的绝缘特性进行了研究,对比分析了地面与太空不同环境中绝缘性能的监测方法,在探讨太空环境电气设备局部放电产生的脉冲电流以及高频电磁信号特性基础上,采用罗氏线圈监测系统电流的变化,采用UHF特高频传感器进行局部放电检测,并提出了空间太阳能电站能量转换与传输系统电流变化与局部放电的具体监测方案。Space solar power station （SSPS） works on the plasma environment and the electrical insulation of SSPS en- ergy conversion system should be researched by particular methods. The simulation of the partial discharge （PD） detection methods in space environment is a key technology to the reliable operation of SSPS. Based on the analysis of the difference in ground and space condition methods, the electrical insulation properties of SSPS conversion system has been studied. The impulse current and high frequency electromagnetic signal of PD was discussed and a specific monitoring method applied in SSPS conversion system is proposed. The Rogowski coil is suggested to monitor the variation of current and the Ultra High Frequency （UHF） sensor is suggested to detect the PD electromagnetic wave.
