摘要
本文根据广州抽水蓄能电站调保计算的成果,分析了不同的水泵水轮机全特性曲线,特别是“S”区特性,对调节保证参数的影响。此外,还对同一特性曲线,因曲线的误差所引起的调保参数的差异进行了分析。
Based on the result of regulative and protective calculation of Guangzhou Pumped Storage Station, the paper analyzes the charateristic curves of pump-turbines, especially the influence of 'S' shape of the curves on the regulative and protective parameters during the hydraulic transients, i. e different characteristic cruves bring about different results of the hydraulic transients. Besides, the difference between the regulative and protective parameters caused by the curve errors is also analyzed for the same characteristic curve
