Abstract: 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.

Key words: fuel gas power plant, automatic voltage-var control system, busbar voltage, communication, power dispatching
