摘要

针对发电机组的一次调频和自动发电控制(AGC)的负荷控制品质与稳定低节流损失运行的机组节能需求产生矛盾的问题

以及现有凝结水变负荷技术和滑压优化技术的局限性

提出了基于凝结水变负荷技术的深度滑压节能控制策略

通过凝结水变负荷提高机组响应电网一次调频和AGC指令的能力

从而实现机组的最优滑压运行。以某亚临界350 MW机组为例，对基于凝结水变负荷技术的深度滑压节能控制策略进行了可行性和有效性验证。结果表明

机组在达到电网考核指标的前提下实现了深度滑压节能自动控制

节流损失大幅降低

每台机组年平均可节约煤耗1.13 g/(kW・h)

按煤价600元/t计算

每年可节约62.2万元

节能效果显著。同时，缓解了长期存在的电网一次调频和AGC考核与机组节能运行的矛盾。
