摘要

为保证火电机组在调峰期间处于低负荷运行时设备的安全、经济及环保性

结合机组的实际可操作性

建立了一套评价机组调峰能力的指标体系。采用层次分析法确定各指标权重

结合模糊综合评判法对机组调峰能力进行评价；选取7台不同容量及不同冷却形式的煤电机组

基于K均值算法聚类

求取各指标值并进行综合评价

根据评价结果进行纵向比较。结果表明:超超临界660、1 000 MW等级机组应在中、高以上负荷参与电网变负荷调峰任务

以更好发挥其能耗水平低的特性；超临界600 MW等级机组变负荷调节性能良好

可在中、高负荷承担变负荷调峰任务

也可适度参与降负荷深度调峰；亚临界600、300 MW等级机组装机数量最多

容量占比最大

可适时参与电网深度调峰；同时在峰谷差矛盾突出的地区或时段

安排亚临界机组参与轮停调峰。
