Alarm setting and disposition principle
The alarm setting point of the present invention " system and its control method for improving head and increasing power station installed capacity " a kind of
For A grades of alarms and B grades of alarms.
A grades of alarms (Sa331) are noncritical failure.PLC operator control panel shows abort situation and fault message.A grades of alarms are not
IHC whole system can be caused out of service.PLC does not need to send the specific fault message details that each A grades is alarmed to water power
It stands Central Control Room；But when occurring A grades of alarm failures for equipment in IHC system, PLC need to once transmit " A grades of fault alarms " signal
Give power station Central Control Room.
B grades of alarms (Sa332) refer to the catastrophe failure that IHC whole system will be caused out of service.PLC operator control panel shows failure
Position and fault message；PLC must be each " B grades of fault alarms " signal and its fault message, while being sent in power station and controlling
Room.
A grades of alarms no matter occur or B grades of alarms, power station Central Control Room require the regulation according to " run book ", send
It sends patrol officer to check to scene, confirmation and handling failure.
The foregoing describe basic principle of the invention and main feature, the description of specification only illustrates original of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.
