电力电子技术在电力发展中的新应用

The New Application of Power Electronic Technology in Power Development

电力电子技术近年已有较快发展,在高压直流输电中,对抑制谐波,降底造价、扩大功能发挥重要作用;在灵活交流输电系统中,更借助于电力电子技术;在水力发电厂中用变频调速产生巨大效益。

Power electronic technology had rapid progress during recent years. In high voltage direct current transmission (HDVC) it plays as a major actor. Advanced electronic technology can further reduce hasmonics and promote performance. Flexible AC Transmission System (FACTS) depends solely on power electronic technology. In hydro plants, power electronic technology makes variable speed operation possible, hence greatly benefit hydro-electric operation.
