【摘要】 针对谐振接地系统在实际应用中即使完全补偿仍会出现残流过大进而影响了电网的安全运行的现象,本文通过理论分析与数字仿真说明了产生这种现象的机理,为解决谐振接地系统的此类问题进而进一步推广消弧线圈的应用奠定了理论基础。更多还原

【Abstract】 In this paper,the mechanism of the phenomenon that there may be an excessive remnant current,which can affect the security of the power network,under fully compensated condition in resonant earthed neutral system is analyzed.By theory analysis and digital simulation,the work of this paper can establish a theory base of solving such kind of problems in resonant earthed neutral system and help to extend the application of extinction coil.更多还原
