摘要
交流电优点主要体现在发电和配电方面。由于采用交流电,使各个不同电压之间的变换、输送、分配和使用都便于实现;HVDC(High Voltage Direct Current Transmission高压直流输电)是目前电力电子在电力系统输电领域应用最为成熟的一门技术。HVDC输电系统是由整流桥和逆变桥通过直流线路连接而成的;柔性直流输电技术是一种基于脉宽调制技术和可关断电力电子器件的直流输电技术。本文主要介绍了这三种输电的基本概念、国内外研究应用实例以及它们各自的优缺点。
The generation and distribution were the mainly advantages of AC. Due to adopting the AC power transmission, it was very convenient to transform different voltage levels,transmit power and distribute power. HVDC was a mature technology based on power e-lectronics device applying transmission. HVDC system was made of the rectifier bridges and inverter bridges. HVDC - Flexible was a kind of technology based on pulse width modulation and power electronics device. The paper mainly introduced the three types of power transmissions （their advantages and disadvantages）, and the application at home and abroad.
