摘要
以定速机组运维成本的分析为基础,对比变速机组与定速机组的结构差异,结合世界上变速机组的实际运行数据,分析了变速机组的运维成本。结果显示变速机组的运维成本与定速机组基本一致,但变速机组的运行时间较定速机组增加了20%以上。
Based on the analysis of operation and maintenance cost of fixed speed unit, the operation and maintenance cost of variable speed pumped-storage unit is analyzed after comparing the structural differences between them and combined with the actual operation data of variable speed unit in the world. The result shows that the operation and maintenance cost of variable speed unit is basically the same as that of fixed speed unit, but the operating time of variable speed unit can increased by more than 20% than that of fixed speed unit.
