【摘要】：抽水蓄能电站工况转换频繁,水力过渡过程关乎整个电站的安全运行和供电品质,一管双机甩负荷是大波动水力过渡过程,对其进行试验分析具有重要意义。为此,分析多个抽水蓄能电站一管双机甩负荷试验数据,统计了转速和蜗壳压力上升率范围,为以后制定相关标准和调节保证计算提供参考;并分析了某抽水蓄能电站一管双机甩50%、75%、100%负荷的试验结果,结果表明该电站转速和蜗壳压力上升率与其他统计电站相近,可为其他电站的类似试验提供参考。
[Abstract]:The hydraulic transition process is related to the safe operation and power supply quality of the whole power station. The load rejection of one tube and two machines is a large fluctuating hydraulic transition process, and it is of great significance to test and analyze it. For this reason, the load rejection test data of one tube and two machines in several pumped storage power stations are analyzed, and the range of speed and volute pressure rise rate is counted, which provides a reference for the formulation of relevant standards and the calculation of regulation guarantee in the future. The test results of 100% load in a pumped storage power station are analyzed. The results show that the rotational speed and volute pressure rise rate of this power station are close to those of other statistical power stations, which can be used as reference for similar tests in other power stations.
