| Abstract: | Based on the Huaneng Yuhuan power plant, this paper discussed the functions of automatic voltage control （AVC） system （including structure, scheduling interface mode, reactive power allocation strategy and control mode） and distributed control system （DCS） logic. Then, the problems existing in the installation, commissioning and operation of AVC sub station were analyzed and some improvement measures were put forward, which could make the operation rate and qualified rate of regulation of the AVC system achieve good, and give full play to its optimization ability in reactive power and voltage in power system. The construction experience of AVC sub station in Huaneng Yuhuan power plant can provide reference for other similar proiects＇ construction in power plants. |
