摘要
本文从抽水蓄能电站改善火电主系统能耗特性出发,提出了系统效率的概念,并给出了系统效率的计算模型.计算表明,同机组效率永远小于1的情形相反,系统效率在本文计算范围内均大于1.越是尖峰区,系统效率越高.建议将抽水蓄能电站系统效率同其机组效率并列,同作为这类电站的重要特征参数.
The concept of system efficiency and the calculation model aregiven on the of the characteristic of Pumped-Storage Plant, which can improve the energe consumption of the thermo-electric generation, the result shows that sgsyem efficiency in the scope of Calculation in this paper is more than 1, which is contrary to that the efficiency of generating set is below 1, the sharper the load, the higher the system efficiency. At last, paper propose that thesystem efficiency paralling with the efficiency of generating unitshould be regaded as a common important parameter to these plant.
