Abstract

Provide an operation management support apparatus for power plant, supporting a maintenance work and preventing a user from violation of the operational safety programs, caused by a human error in case where a power plant temporarily deviates from LCO. The operation management support apparatus for power plant includes: an alarm device 12 that compares a plant data measuring by sensors 3a-3x installed in a nuclear power plant 2 with preset alarm the value and generates an alarm output instruction signal for instructing an alarm output in case of determining that the power plant is abnormal; an operational safety program DB 14 that stores an information in relation to an operational safety program of the power plant; an support device 13 that extracts an information in relation to the operational safety program of which the alarm output represents a conflict from the operational safety program DB 14 based on the plant data in relation to the alarm output in case of receiving the alarm output instruction signal; and a display device 15 (16) that displays the plant data and the information in relation to the operational safety program, extracted by the support deice.

Claims

1. An operation management support apparatus for power plant comprising:

an alarm device that compares a plant data measuring by a sensor installed in a power plant with preset alarm the value and generates an alarm output instruction signal for instructing an alarm output in case of determining that the power plant is abnormal;

an operational safety program storage that stores an information in relation to an operational safety program of the power plant;

an operational safety program extraction device that extracts an information in relation to the operational safety program against which the alarm output becomes, from the operational safety program storage on the basis of the plant data in relation to the alarm output in case of receiving the alarm output instruction signal; and

a display device that displays the plant data and the information in relation to the operational safety program, extracted by the operational safety program extraction device.

2. The operation management support apparatus for power plant according to claim 1, further comprising an input device that receives an instruction for displaying any one of the plant data and the operational safety program.

3. The operation management support apparatus for power plant according to claim 2, wherein the information with respect to the operational safety program includes any one of a limiting condition for operation, a condition so that the operational safety program is applied, a required action and an allowed outage time, in each article of the operational safety program displayed on the display device.

4. The operation management support apparatus for power plant according to claim 3, further comprising a selection device that receives an instruction for selecting from the required action displayed on the display device;

a timer device that starts to time in a case of receiving the instruction for selecting from the required action,

wherein the display device displays a time timed by the timer device and the allowed outage time of the required action based on the instruction.

5. The operation management support apparatus for power plant according to claim 1, further comprising a maintenance work history storage that stores contents of a maintenance work occurred during a time from an alarm output to completion of recovering from abnormal state and a time of occurrence of the maintenance work.

6. The operation management support apparatus for power plant according to claim 1, further comprising a plant data extraction device that extracts plant data in accordance with a search condition which is input and includes any one of a tag number, a plant data name, a system and a free word, and transmits the plant data in accordance with the search condition to the display device.

7. The operation management support apparatus for power plant according to claim 1, further comprising an operational safety program extraction device that extracts the operational safety program in accordance with a search condition which includes any one of a tag number, a plant device name, a system, a device type, and a free word, and transmits the operational safety program in accordance with the search condition to the display device.
