摘要
结合西北某直接空冷火电厂的实际情况,分别对不同背压、风机风速和风机台数进行组合。采用年总费用最小法对直接空冷系统进行优化计算,对比分析各组合年总费用,最终得出最优方案,满足发电机组正常运行要求。
Based on actual operation condition of a direct air cooling system in a coal-fired power plant in northwett China, an analysis was conducted on different combinations of the back pressure, fan velocity and fan quantity. Taking minimum total annual cost of the direct air cooling system as a target, anoptimized calculation was performed, and subsequently an optimal scheme was obtained throughcomparative analysis on different schemes of the total annual cost, which can satisfy operation requirements of the coal-fired power unit.
