自动发电控制(AGC)控制策略优化的研究和应用

在吴泾二电厂1、2号机组变负荷速率的测试、分析和计算的基础上,对协调控制功能进行改进和调整,使机组在安全的前提下,有较好的负荷调节性能,满足电网调度对变负荷速率的要求,并在频繁的AGC变负荷工况下减小机组的汽压、汽温的变化幅度.对原协调控制系统作了较大的修改,采用了"智能化"变负荷控制策略,使变负荷快速、准确和稳定.

Study of AGC control strategy optimization and its application

Based on the test,analysis,and computation of load change rate for the No.1 and No.2 units in Wujing No.2 Power Plant,the coordinated control function of the units was improved and adjusted to ensure the good load adjusting performance in the precondition of unit safety.The requirement of grid dispatching for load change rate can thus be met,and the changing of steam pressure and temperature of the unit can be reduced during frequent load change under AGC.The original coordinated control system was modified greatly,and the "intellectual" control strategy for load change was adopted to realize quick,accurate,and stable load change.
