柔性直流输电技术在电力系统中的应用

Application of the flexible high voltage direct current technology in power system

柔性直流输电技术是指通过IGBT、IEGT等全控型器件对有功功率和无功功率进行独立控制,应用该技术对现有电网系统进行改造不仅可以全面增加电网系统输电的灵活性,还能在一定程度上缓解由于输电线路空间过小导致输电性能差的问题。通过分析和总结柔性直流输电技术的特点,针对其在新能源发电并网、城市商业区电力增容、特殊地区高压输电等领域的应用进行了探讨,以期为电网建设工作提供一定的参考。

The flexible high voltage direct current(HVDC)technology is independent control of active power and reactive power through IGBT,IEGT,and other fully controlled devices.The application of this technology to the transformation of the existing power grid system can not only increase the flexibility of the power grid system but also alleviate the problem of poor transmission performance caused by too small a transmission line space to a certain extent.This paper analyzes and summarizes the characteristics of flexible HVDC technology,and discusses its application in grid connection of new energy power generation,power capacity increase in the urban business district,and high voltage transmission in special areas.This study is expected to provide some reference for the construction of a power grid.
