随着大功率开关器件的发展,电力电子技术在电力系统中的应用已成为可能。本文介绍利用 GTO 元件组成的电压源逆变器作为主体部分的新型静止无功发生器。文中涉及其配置,主要工作原理,以及和同步补偿机,静止无功补偿器等的比较。由于静止无功发生器的优越性能,随着电力电子元件价格的下降,最终必将替代现有的无功补偿装置。 With the development of high-power switching devices, the application of power electronic technology in power system has become possible. This article describes a new static var generator that uses a voltage source inverter consisting of GTO elements as the main part. The article relates to its configuration, the main working principle, as well as the synchronous compensation machine, static var compensator comparison. Due to the superior performance of STATCOM, as the price of power electronic components declines, it will eventually replace the existing reactive power compensation device.
