提出了三峡梯级电站日运行容许控制问题，阐明了其重要性，探讨了此类问题的特点和解决途径。导出了连续模型的时滞Ｅｕｌｅｒ方程和广义端点条件，说明了其实际含义；解释了主散模型的合理性并给出了计算实施细节与软件，对数值结果进行了分析，针对有关问题提出了相应建议。

The feasible control problem is presented for the day-operation of the Three-Gorge Caseade Hydropower Station. The significance of the problem is explained. Basic propetties ofthe problem and the approaches to study it are discussed. Two methfods are given for solving theproblem. which are calculus of variation and linear programming. In the former. the Euler equationwith time-lag and the generalised two-point boundary conditions are obtained and the correspondingpractical implication is interpreted. In the latter. the rationality for the discrete model is exptainedand the computalional details are given for the implement software. some questions which should bepaid much attentfon and the corresponding propeels are prasented based on the numerical results andtheoretical analysis
