Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings.
[0019] Such as figure 1 As shown, the present invention provides a method for alarming in a unit-level self-start-stop control system, wherein the control system is divided into several breakpoints, and the method includes: determining that the unit-level self-start-stop control system satisfies input Condition S21: starting from the first breakpoint of the unit-level self-start-stop control system, determine whether the feedback signals of each breakpoint meet the preset condition S22 of the breakpoint, wherein, when the preset condition is met, judge whether to detect To the fault occurrence signal S23, if a fault occurrence signal is detected, an alarm signal is generated and the unit-level self-start-stop control system is maintained at the current state S26, if no fault occurrence signal is detected, the feedback signal to the next breakpoint Judging S24; and giv...

The invention discloses a method and a device for giving an alarm in a unit-level self start-stop control system. The control system is divided into a plurality of break points. The method comprises the following steps: determining that the unit-level self start-stop control system meets the input condition; judging whether feedback signals of the break points meet the preset conditions of the break points from the first break point of the unit-level self start-stop control system in sequence, if the preset conditions are met, judging whether a fault signal is detected, if the fault signal is detected, generating an alarm signal and keeping the unit-level self start-stop control system in a current state, and if the fault signal is not detected, judging the feedback signal of the next break point; and giving an alarm according to the alarm signal. According to the method and the system provided by the invention, the alarm can be given in the case of a fault to remind an operator and keep the unit-level self start-stop control system in the current state, so that the running safety and reliability of the system are improved.
Description
technical field [0001] The invention relates to the field of monitoring, in particular to a method and device for alarming in a unit-level self-start-stop control system. Background technique [0002] The Automatic Plant Startup and Shutdown System (APS for short) divides the unit-level automatic startup and shutdown process into several breakpoints, that is, functional groups, and automatically completes the entire process of unit-level startup or shutdown. With the improvement of the degree of automation of power plants and the requirement of reducing staff and increasing efficiency, the demand for APS is also increasing. There are more and more units designing APS in thermal power and gas turbines. APS has high requirements for unit automation and requires full automatic operation. Including that when the equipment is not running, it should be put into the "automatic standby" state automatically, and it will enter the normal process control state after the equipment is ...
