交直流混合输电线路技术研究
摘 要
交直流混合输电线路是一种结合了交流输电和直流输电优点的新型电力输电技术。其应用于电网输电、大型风电场、特殊场合等领域，具有提高电力系统输电效率和稳定性、方便可再生能源大规模利用、为紧急场合提供可靠的电力保障等多重优点。该技术的历史由来可以追溯到20世纪初，但直到近年来随着电力系统的不断发展和可持续性能源的广泛应用，才逐渐受到广泛关注和应用。其原理是通过在一定距离上的传输线中通入高频交流电，再通过换流器将交流电的功率转化成高压直流电，最终输送到目标地点进行利用。为确保其正常运行，需要进行导线选择、电源管理、调节器设计和防护等方面的结构设计，在电网输电、大型风电场和特殊场合中都有着广泛的应用实践。
AC/DC hybrid transmission line is a new type of power transmission technology that combines the advantages of AC transmission and DC transmission. It is used in grid transmission, large-scale wind farms, special occasions and other fields, and has multiple advantages such as improving the efficiency and stability of power system transmission, facilitating the large-scale utilization of renewable energy, and providing reliable power guarantee for emergency occasions. The history of this technology can be traced back to the early 20th century, but it has not been until recent years that it has gradually received widespread attention and application with the continuous development of power systems and the widespread application of sustainable energy. The principle is to introduce high-frequency alternating current into the transmission line at a certain distance, and then convert the power of alternating current into high-voltage direct current through the converter, and finally transmit it to the target location for utilization. In order to ensure its normal operation, structural design in wire selection, power management, regulator design and protection are required, which are widely used in grid transmission, large wind farms and special occasions.
