摘要
随着电网规模的日益扩大,用电负荷变化越来越快,传统手动调节电网频率的方式已经很难满足现实需要,而采用自动发电控制(AGC)能够自动、快速地减小供需偏差,保证了电能质量。文中介绍了自动发电控制的核心部分单元机组协调控制,该系统以(p1/pe)p0作为锅炉热量与汽轮机能量需求间的联络信号进行调节。目前,天津电网200MW等级及以上机组全部具备投入AGC功能,对提高电网自动化水平发挥了重要作用。
With the growing scale of power grids, electric load changes faster and faster, the traditional way of manually adjusting the grids frequency requlation has been difficult to meet real needs, automatic generation control (AGC) ensures power quality through automatically and rapidly reduce the supply and demand deviation.This article describes the unit coordinated control of core of automatic generation control.The system regulates boiler heat and turbine energy demand with (P1/Pe)P0 as regulated signal. At present, units of Tianjin grid all have input AGC functions over 200MW, which improves the automation level and played an important role.
