Large hydropower station fast gate falling control method
The invention relates to a door falling control method for a large hydropower station fast door, which comprises the following steps of: performing logic OR operation on five paths of door falling control signals to obtain an output signal acting on the large hydropower station fast door to finish door falling; the first path of door falling control signal is a high-speed door falling button signal or a high-speed door falling relay signal or a simulation return screen emergency high-speed door falling button signal; the second path of door falling control signal is a unit shutdown signal of one type of mechanical accident shutdown; the third path of door falling control signal is a rapid shutdown process starting signal; the fourth path of door falling control signal is an emergency shutdown process starting signal; and the fifth path of door falling control signal is a low-oil-pressure and low-oil-level signal of the hydraulic system of the speed regulator of the unit. According to the method, the reliability of door falling protection action is greatly improved, the potential hidden danger that a traditional single signal outlet or a high-speed door falls by mistake due to signal jitter is eliminated, the risk hidden danger that the outlet is mistakenly operated at a single point is thoroughly eliminated, and plant flooding accidents, serious casualties and damage to equipment and facilities can be effectively prevented.
本发明涉及大型水电站快速门落门控制方法，所述方法对五路落门控制信号进行逻辑或运算，得到作用于大型水电站快速门完成落门的输出信号；第一路落门控制信号为落快速门按钮信号或落快速门继电器信号或模拟返回屏紧急落快速门按钮信号；第二路落门控制信号为一类机械事故停机的机组停机信号；第三路落门控制信号为快速停机流程启动信号；第四路落门控制信号为紧急停机流程启动信号；第五路落门控制信号为机组调速器液压系统低油压、低油位信号。本发明大幅提高落门保护动作的可靠性，消除传统单一信号出口或信号抖动误落快速门潜在的隐患，彻底消除了单点误动出口风险隐患，能有效防范水淹厂房事故的发生、重大人员伤亡和设备设施的损坏。
