660MW火电机组深度调峰协调控制优化及应用

Optimization&application of deep peak-shaving coordinated control of 660MW thermal power unit

目前,我国大部分火电机组的调峰范围是50%~100%额定负荷,随着各地区并网发电厂辅助服务管理实施细则的发布,深度调峰对于火力发电厂越来越重要。文章针对660MW火电机组在深度调峰中协调控制技术进行了深入研究,提出了一套协调控制策略优化措施,并在福建华电邵武项目新建4号机组进行了35%~100%额定负荷的AGC协调变负荷试验,结果表明,该协调控制策略切实可行。

At present,the peak-shaving range of most thermal power units in China is 50%-100% rated load.With the release of the implementation rules of auxiliary service management for grid connected power plants in various regions,deep peak-shaving is becoming more and more important for thermal power plants.This paper has conducted in-depth research on the coordinated control technology of 660MW thermal power unitin deep peak-shaving,a proposed a set of coordinated control strategy optimization measures,and conducted 35%-100% rated load AGC load change test at Unit 4 in Fujian Huadian Shaowu project.The test results show that the proposed coordinated control strategy is feasible.
