Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring device for a power plant.

[Conventional technology]

FIG. 2 is a system configuration diagram showing a conventional power plant monitoring device disclosed in, for example, Japanese Unexamined Patent Publication No. 59-99944. (3) an alarm signal to detect a failure of the control device;
(4) is the central panel in the central control room; (51 is the alarm display window attached to the central panel; 16+ is the alarm output time C: It is a bell to warn you.

Next (2 operations will be explained. In the power plant monitoring system (=), each equipment/control device of the plant (1) C2) If an abnormality occurs, this will be sent as an alarm signal (2) to the alarm display device (3) = This signal is transmitted as an electrical signal to the alarm display window (510) provided in the center panel (4).
When the lamp is turned on, the operator in the center will be informed of the abnormality by sounding a bell (6 buzzer, etc.). Next, the operator will see the displayed alarm signal and various indicators/recorders, and then (: Go to the site where an abnormality is occurring and discover the cause of the abnormality.

[Problem that the invention seeks to solve]

Conventional power plant monitoring equipment is configured as described above, so one of the hundreds of alarm display windows provided on the central panel is displayed. It is necessary to determine the cause of an abnormality by selecting and observing indicators, etc., and to know what kind of abnormality is occurring (second, many years of experience is required to know what to check). There were also problems such as large individual differences.

This invention was made in order to solve the above-mentioned problems.In addition to displaying an alarm when an abnormality occurs, a list of inspection items for investigating the cause is selected from the alarm display items and output, so that errors can be quickly corrected. The purpose of the present invention is to obtain a monitoring device that can find the cause of abnormality in a plant.

[Means for solving problems]

According to this invention, when the alarm display device receives an alarm signal, the power plant monitoring device according to the present invention rings a bell on the center panel and lights up the alarm display window. A list of inspection items with items to be checked is output to the central control room (two outputs).

[Effect]

In this invention, the inspection item list is determined from the alarm display device (: alarm signal items input from the outside),
The corresponding list is output to the center.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, (1) is a control device that is one of the monitoring targets, (
2) is an alarm signal that emits a -signal when an abnormality occurs in the control device, (3) is an alarm display device that receives the alarm signal and converts it into a signal to be displayed at the center, and (4) is a system where an operator is always on duty. (51 is an alarm display window provided in the center panel, (6) is a central panel!= installed, and at the same time the alarm display window lights up, a sound sounds to notify the operator; ( 7) is a central control room storage: installed printer for outputting an inspection item list (61 is an inspection item list);

Next, the operation will be explained. According to the present invention, if an abnormality occurs in each device of the plant or the control device fi+, this is transmitted as an alarm signal (2) to the alarm display device (3).

The alarm display device first converts the alarm signal into an electrical signal and sends it to the central panel (
4) The lamp in the alarm display window (51) lights up and the bell +61 rings to notify the operator in the center (: The type is determined, the indicator/recorder to be checked and the inspection location are selected, and based on this, the list of inspection items to be output is selected, and the list of inspection items is output from the preset (7) provided in the center.

As described above, 1: The operator can not only know the alarm that has been output but also obtain a list of inspection items, allowing the operator to quickly detect abnormal phenomena and move on to the next operation. It turns out.

In addition, in the above embodiment, the inspection item list is printed on the printer (7).
Although a method that outputs more information is shown, the same effect can be obtained by installing a CRT in the center and allowing the operator to view the list of inspection items displayed on the CRT screen.

〔Effect of the invention〕

As described above, according to the present invention, since the inspection item list is output together with the alarm display, it is possible to obtain a power generation plant monitoring device that can promptly and correctly respond to plant abnormalities regardless of the operator's experience. effective.

[Brief explanation of drawings]

FIG. 1 shows a power plant monitoring device according to an embodiment of the present invention, and FIG. 2 shows a conventional power plant monitoring device. (11 is the control device, (2) is the alarm signal, (3) is the alarm display device, (4) is the center panel, (51 is the alarm display window, (61
is a bell, (7) is a precipitator, and (81 is an inspection item list. In addition, the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Claims] A power generation plant monitoring device, characterized in that it displays an alarm when an abnormality occurs, and outputs a list of inspection items corresponding to the abnormality that has occurred.
