摘要
电厂侧自动电压控制是实现全网自动电压控制的一个重要组成部分。介绍了电厂侧自动电压控制实现的原理,列举了三种实现方法,并对这三种实现方法进行了比较,提出了基于火电厂的电厂侧自动电压控制器的具体设计方案。通过仿真验证和分析说明,电厂侧自动电压控制器可以代替发电厂运行人员手动调节发电机励磁系统的工作,自动调节发电厂的母线电压和无功值,具有实际应用价值。
Automatic voltage control（AVC） was one of the important measures to ensure safety, dependability, economical and high quality operation of the power system. This paper introduced the principle of AVC in plant site, enumerating three realization methods, and making a comparision between them. An automatic voltage controller was designed which could be suitable for thermal power plant. The application result and analysis illustrate that automatic voltage controller in plant site can substitute operating personnel to deal with manual adjustment generator excitation system with high evaluation in practical application.
