电压无功自动控制系统在燃气电厂的应用

广东惠州天然气发电有限公司新投运的电压无功自动控制系统（AVC）是中国南方电网的首家试点工程。介绍了AVC自动装置的运行方式、调节原理、逻辑构成以及厂内各系统之间的通讯与控制方式。通过AVC自动装置的应用，使系统电压和无功储备保持在较高的水平，大大提高了电网的安全性和机组运行的稳定性。

Application of automatic voltage-var control system in fuel gas power plant

The automatic voltage-var control system （ AVC ） which was newly used in Guangdong Huizhou Liquefied Natural Gas Power Corporation Limited is the first experimental unit project of China Southern Power Grid. The running mode, the adjustment principle, the logic composing of the AVC automatism equipment and the communication among systems was introduced in this article. The electric power system voltage and the reactive power reserve were held in rather higher level through the application of the AVC system. The security of the power grid and the stability of the generator set were greatly improved.
