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 device.

Claims

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

an alarm device that compares a plant data measured by a sensor installed in a power plant with a preset alarm value, and generates an alarm output instruction signal for instructing an alarm to be output in a case of determining whether 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, the information including a limiting condition for operation, a condition to which the operational safety program is applied, at least one required action, and an allowed outage time, in each of articles of the extracted operational safety program;

an operational safety program extraction device that associates an event that causes the alarm output with an article of the operational safety program, and extracts an information in relation to the operational safety program against the event which causes the alarm output from the information stored in the operational safety program storage on the basis of the plant data in relation to the alarm output in a case of receiving the alarm output instruction signal;

a display device that displays the plant data and the condition, the at least one required action, and the allowed outage time, in each article of the extracted operational safety program, included in the extracted information;

a selection device that receives an instruction for selecting at least one required action selected by a user from the at least one required action displayed on the display device, and an instruction for changing the at least one required action selected by the user into a new at least one required action selected by the user if a necessity of changing the at least one required action is caused by finishing a required action of the at least one required action;

a timer device that starts a time in a case of receiving the instruction for selecting the at least one required action or changing the at least one required action, in accordance with the allowed outage time information included in the extracted information; and

a countermeasure extraction device configured to extract the at least one required action and each allowed outage time of the at least one required action, and to extract the new at least one required action and each allowed outage time of the new at least one required action if the selection device receives the changing instruction,

wherein the operational safety program extraction device is configured to extract the at least one required action and each allowed outage time of the at least one required action, and to extract the new at least one required action and each allowed outage time of the new at least one required action if the selection device receives the changing instruction, and

wherein the display device is configured to display a time timed by the timer device, the at least one required action, and each allowed outage time of the at least one required action, and to display the new at least one required action and each allowed outage time of the new at least one required action if the selection device receives the changing instruction.

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 displayed information further includes the limiting condition for operation 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 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 the abnormal state and a time of occurrence of the maintenance work.

5. 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.

6. The operation management support apparatus for power plant according to claim 1, further comprising an operational safety program search 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.
