Embodiment Construction
[0011] The present invention will be further described below in conjunction with accompanying drawing.
[0012] as indicated figure 1 As shown in , it is a schematic diagram of the quick realization of the action of the steam turbine emergency protection system.
[0013] Based on the principles of simplicity, directness, independence, and speed, the present invention makes full use of the programmable functions of complex programmable logic arrays and the high speed of complex digital logic operations. In the design, the monitored steam turbine parameter digital signal After being processed by the digital input channel, it directly enters the complex programmable logic array, and after a given logic judgment, the complex programmable logic array directly outputs the trip signal to the digital output channel, which will avoid switching, expansion and conversion to the greatest extent. Wait for the middle link.
[0014] In the present invention, when the ETS system receives a ...
