The countermeasures for main technical issues of the design of the computer supervisory and control system for continuous five-lift ship lock of Three Gorges Project
2003
Based on the analysis of the operation mode of the continuous five-lift ship lock of Three Gorges Project,this paper presents the countermeasures for main technical issues of the design of the computer supervisory and control system for continuous five-lift ship lock of Three Gorges Project, such as the reliability of the system,flexibility of the operation mode,judgment of the cascade numbers in operation,calculation of the quantity of filling water,diminishing the extra-filling and extra-discharging,avoiding the colliding of two doors at the end of closing,avoiding the closing failure and avoiding different gates open at same time. This paper points out all these measures have been proved to be essential and indispensable in accordance with the trial operation under low water head. For the water head will rise in the future,the ship lock will operate under more critical conditions,and the exploration,adjustment,improvement of the control system shall be continued.
