摘　　要：内部过电压是特高压研究中最为重要的研究课题之一。由于国情不同,日本和我国在特高压线路的设计和内部过电压的限制方案上具有明显差别,值得比较和借鉴。比较了日本和我国在限制内部过电压方法上的差异,研究了在无功补偿、工频过电压、潜供电流和操作过电压等方面的不同限制情况,结果表明不同的限制方案都能达到理想的限制效果。The internal overvoltage problem is one of the most important subjects in UHV researches.Due to the different national conditions,there are many noticeable and valuable differences between Japan and China in designs of high voltage lines and internal overvoltage limitation.This paper compares the differences between Japan and China in their internal overvoltage limiting methods,and studies the different limiting methods in different aspects such as reactive power compensation,power frequency overvoltage,secondary arc current and switching overvoltage.The results show that all the different limiting methods of them can achieve ideal limitation effects.
