The invention relates to a power generation post-evaluation system and method for a cascade power station. The system comprises an information acquisition subsystem for acquiring data, a post-evaluation subsystem for receiving the data and performing post-evaluation analysis, and a man-machine interaction subsystem for displaying, outputting and feeding back post-evaluation conclusions. According to the invention, the maximum theoretic generating capacity is computed through a genetic algorithm based on water level guiding, and the computation accuracy, convergence and convergence rate of an optimization scheme model are improved. The method adopts the genetic algorithm based on water level guiding to optimally compute the maximum annual theoretic generating capacity of the cascade power station, thus changing the present situation of computing and checking electrical quantity only according to a scheduling graph in post-evaluation work of the traditional cascade power station, and simultaneously remedying th
