Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a driving guide device.

[Background of the invention]

In current plants, operators learn and train to operate under various operating conditions at an operator training center.

However, as the reliability of power plant equipment has improved, the occurrence of abnormal conditions (including normal plant trips) (1) has become extremely rare. Therefore, there are fewer chances for the operator to carry out driving operations in various operating states. However, once an abnormal condition occurs, reliable and appropriate operation is required.

Therefore, it is necessary for operators to deepen their understanding of as many abnormal events as possible, but training at training centers alone has its limits. Therefore, we developed an operation guide system that combines a simulator that can generate various abnormal events and respond in response to operation operations, and an operation guide that indicates the operation operations and plant conditions that should be monitored when the event occurs. It is hoped that it will be introduced.

[Purpose of the invention]

The present invention uses a simulator to make it easier to understand abnormal conditions that do not normally occur in a plant, and provides an accompanying operation guide to enable operation training, thereby improving operational reliability. This is an attempt to dramatically improve improvement.

[Summary of the invention]

(2) The present invention includes an operation console installed in a central control room, a simulator that simulates plant characteristics, and a switching device that switches signals between the simulator and the actual plant.
Depending on the signal indicating an abnormality in the plant, the signal exchanged with the operation console is switched from the simulator to the actual plant.
The present invention is characterized in that it is possible to output a plant operation guide depending on the state of the plant or the simulator.

[Embodiments of the invention]

Examples of the present invention will be described in detail.

FIG. 1 shows an embodiment of the invention. The configuration includes an operation console 1, a switching device 22 for switching between a process and a simulator, a process control/interlock circuit 27, an operation guide device 4, and a plant simulator 3.

Switching device to connect console 1 and simulator 3! 22. This is called simulator mode.

In the simulator mode, signals from the operation switches of the operation console (3) 1 are applied to the plant simulator 3. The operation guide device 4 linked to the plant simulator 3 outputs to the operator an operation guide corresponding to the response of the plant simulator and the operation switch information 23. During this time, the process is automatically controlled and operated by a control device (including equipment interlock) 27 without manual operation by an operator.

When an abnormality occurs in the process, the console 1 is connected to the process by the switching signal 29 (abbreviated as process mode), and as a result, the process signal 25 and the signal 26 from the control device are output to the console. Further, pass through the switching bag [22.

The console 1, the process status signal 25, and the control device signal 26 are switched to the operating guide, and the operating guide is issued depending on the response of the plant.

When the console 1 is switched from the simulator mode to the process mode, the problem is the switch (4) position of the operation switch installed on the console 1. Normally, the switch position is a three-position switch, taking a valve as an example: fully open, automatic, and fully closed, with a spring return from the fully open/closed position to the automatic position. This type of switch does not cause problems associated with simulator mode/process mode switching.

However, there are some switches that do not spring return to the automatic position. For example, in the case of a valve switch, this is a type of switch that is held in the same position after an opening/closing operation, or a pull-and-hold type switch, in which the operation result continues to be held. In this case, as shown in the second rIR, scan the program to check whether the position of the operation switch on console 1 has returned to the same position as the position of the operation switch immediately before switching to simulator mode, and return it to the original position. After confirming that the operation switch position has returned to normal, complete the switch from simulator mode to process mode.

However, this method requires unnecessary operations when switching modes when an abnormality occurs. Therefore, the console 1 is equipped with only a switch that springs back to the automatic position (5) instead of a contact holding type switch.

That is, as shown in Figure 3, the switch on the console is
Only non-contact holding type, position holding function is available.

By adopting a method in which logic circuits are used on the process side of the switching device, that is, within the control device [27], the work shown in FIG. 2 does not occur, and the problems caused by not restoring can be avoided.

Since the function of the plant simulator is installed in the actual operation control room of the process, the initial values of the plant state and operation console state when switching to the simulator mode can be used as the initial values of the simulator. In the present invention, it is possible to adopt the plant state as the initial value of the simulator mode. As a result, when simulation training is performed, even if various malfunctions occur during the simulation, the state of the process console can respond as expected when such malfunctions occur. It is possible to check whether If the expected response is not achieved (6), it becomes possible to discover which part is at fault.

When connecting a simulator and a console for driving training and learning, adding a driving guide to the simulator allows for even more comprehensive training. That is,
The simulator generates various malfunctions and outputs plant responses, and by providing an operation guide that is tailored to the plant situation, it becomes possible to understand and learn about operation operations more deeply.

In particular, if the current state of the plant and the state of the operation switches on the console are used as the initial values of the simulator mode, a corresponding operation guide will be output in the unlikely event that a similar malfunction occurs. If the driving operation differs from the one specified in advance, by investigating the cause, it becomes possible to identify malfunctions in the operation console, etc., which are difficult to discover in advance.

In this way, not only driving training but also early detection of malfunctions (7) It can also be an effective means for detection.

The driving console] is used for driving operations, so it may not be suitable for use in training and learning.

In such cases, a dedicated training console may be prepared in place of the driving console.

In that case, the situation will be as shown in FIG. That is, in FIG. 1, the operating console and the training console are shared, so the switching device [22] switches between the simulator mode and the process mode, but in the case of FIG. 4, the simulator uses a dedicated console. have In this case, training and learning can be done on a console that is completely separate from plant operations. However, by incorporating a plant simulator/operation guide into a process computer for a plant, it is possible to effectively utilize the process computer during normal steady operation of the plant.

Now, if it is possible to change various malfunctions in a plant simulator, the malfunctions of other plans 1- including the plant can be fed back (8), thereby enabling more diverse training and learning.

[Effects of the Invention] By implementing the present invention, plant operators are able to carry out constant operation training and learn the plant's response.

Also, with the current state of the plant and console as the initial value,
By starting the simulator mode,
If a malfunction is detected, the operator can identify the cause and take countermeasures to prevent the malfunction from occurring.
