Load rejection test and numerical simulation research of #8 unit in Zhexi Hydropower Station

通过开展甩负荷试验与数值仿真的研究,建立过渡过程仿真数学模型,同时基于历次试验结果对数学模型进行优化。针对柘溪水电厂~#8机组的仿真计算及试验研究表明：通过对数学模型及计算参数的修正,能够使计算结果与试验结果吻合。说明可以通过计算分析机组在各典型工况下的甩负荷过渡过程,确保其满足调节保证的要求。

Through load rejection test and numerical simulation research, the mathematical model of transient process simulation is established and optimized based on all the previous test results. Study shows that the results of simulation is consistent with that of test by modification of mathematical model and calculation parameters. It explains that using the numerical simulation can analyse the load rejection transient process in each typical condition and make sure the transient process meet the requirement of regulating guarantee.
