Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant simulation device for conducting operation training of a hydroelectric power plant.

(Prior art) With the recent increase in the size of thermal and nuclear power plants, many hydroelectric power plants have constructed pumped-storage power plants that use the surplus power to pump water and generate power using that water during peak loads. It is the mainstream of hydropower plants. This pumped storage power plant is composed of a plurality of units and has a large capacity. In addition, there are many types of operation such as power generation operation, pumping operation, phase adjustment operation, test operation, etc. In each operation mode, start control, flow rate control, AFC control, ALR control, A
QR control, independent operation control, program operation control, etc., and the control forms are various. Moreover, these operation controls are fully automated and the plant is unmanned, and normal operation is performed by a single person from a remote control station.

(Problems to be Solved by the Invention) An operator who operates and manages such a hydroelectric power plant by himself from a distant place is not only a normal operating operation when the plant is normal, but also a control device at the site due to loss of control power or the like. In the event that remote control becomes impossible, you must go to the site and take appropriate measures. for that purpose,
It is necessary to be familiar with the operation of the on-site equipment corresponding to the various operation modes described above, and regular training is required. But,
The current plant simulator for operation training is limited to operation training conducted from a remote control station.Operation training for on-site equipment when control power is lost depends on learning using system block diagrams and manuals. Did not. For this reason, the degree of understanding is low, and there is a problem that when the user actually comes to the place, it is not possible to quickly and appropriately deal with the plant abnormality.

Accordingly, it is an object of the present invention to provide a plant simulation apparatus having a high training effect that can perform operation training for on-site equipment when control power is lost, with a sense of realism.

[Structure of the Invention] (Means for Solving the Problems) In the present invention, a simulated site panel simulating a site panel at a site is provided separately from the simulated control panel, and a trainee operates the various operation switches on the panel. Simulate the plant response according to
The simulation result is sent to the simulation site panel again, and instruments and the like on the panel are moved.

(Operation) With this, the trainee can perform the operation training for the on-site panel with a sense of reality when remote control by the monitoring control panel becomes impossible when the control power is lost, and the highly effective loss of control power is achieved. We can perform driving training at the time.

(Example) FIG. 1 shows a configuration of a plant simulation apparatus according to an example of the present invention.

The simulation control panel 1 simulates a control panel for monitoring and controlling the plant state of a hydroelectric power plant at a remote location, and displays on the panel a switch 2 for performing various automatic controls and a plant state. Instrument 3 is attached. The simulation site board 4 simulates the site board at the site,
A switch 6 attached to the on-site equipment, a solenoid 6 having a self-contact 5 that can be manually operated, an instrument 7 for displaying a plant state, and the like are provided. The simulation device 8 is for simulating the sequence control circuit of the plant and the data of various electric and mechanical quantities of the plant, and a simulation operation unit 9 for actually performing the simulation operation.
It comprises an input / output unit 10 for interfacing the monitoring control panel 1 and the field panel 4. The input / output unit 10 in the simulation device 8 is connected to an instructor console 11, to which a switch 12 for commanding a control power loss accident is attached.

Next, FIG. 2 shows a detailed circuit configuration of the on-site panel 4 and the input / output unit 10 in the simulation processor 8 when an operation of stopping the main engine is performed when the control power is lost. An input / output unit 10 in the simulation processor 8 includes a generator wattmeter 7A and a tachometer 7B mounted on the panel of the field panel 4, and a load adjustment setter 13 which can be manually operated to increase or decrease the generator output. Is connected. The power source P in the simulation processor 8 is connected to the self-contact 5 described above, and a contact 14 for a generator breaker and a contact 1 for an excitation breaker connected in parallel with the self-contact 5 for operating various field devices.
5. Via the contact 16 for operating the guide vane, the contact 17 for operating the inlet valve, and the contact 18 for applying the brake, the signal is again input to the input / output unit 10 in the simulation operation device 8.

When the switch 2 on the monitoring and control panel 1 is operated in the above configuration, the simulation operation unit 9 in the simulation operation device 8 causes the control process of the plant, the generator voltage, the generator power,
It simulates various plant conditions such as the number of revolutions, and displays the simulation results on the monitoring and control panel 1 and the instruments 3 and 7 on the field panel 4 via the input / output unit 10.

In this state, when performing a manual stop training of the main engine at the time of control power loss, the instructor turns on the control power loss accident setting switch 12 of the instructor console 11. As a result, non-operation of the sequence control circuit and the control device is simulated, and the failure content is displayed on the display of the monitoring control panel 1 and the field panel 4. The trainee, as shown in FIG. 3, shows the operation procedure. (A) When a control power loss accident occurs, (b) promptly disconnects the main engine from the system and stops the While turning on, the load adjusting setter 15 is manually operated to reduce the load while watching the generator wattmeter 7A and the tachometer 7B on the site panel 2. Next, after confirming that the power meter 7A has dropped, the contacts 14 to 18 for the on-site devices are sequentially operated to (c) open the generator circuit breaker, (d) open the excitation circuit breaker, E) Fully close the guide vane and (f) fully close the inlet valve. Finally, (g) operating the contact 18 for the field device while applying the brake while checking the tachometer 14, (h) the main engine stops.

In this way, the main machine is stopped, but when the manual operation procedure of the on-site equipment is erroneous, the simulation calculation unit 9 simulates the plant state according to the erroneous operation, and changes the plant abnormal state which is the simulation result. Instrument 3 on monitoring control panel 1 and on-site panel 4
Displayed on upper instruments 7A and 7B.

Thereby, the trainee can recognize the operation result of the field device due to his own erroneous operation.

As described above, according to the present embodiment, apart from the monitoring and control panel for monitoring and controlling the plant state, by providing the on-site panel capable of manually operating the on-site equipment, the operation training of the on-site panel at the time of a control power loss accident is provided. It can be done with a feeling, and the training effect can be further enhanced.

In this embodiment, the command for the control power loss accident is issued by operating the switch 12 which is the movable contact of the instructor console 11, but the keyboard data of the CRT console is used instead of the switch 12, and the data of the keyboard is used. The same applies to the input to the simulation operation device 8.

[Effects of the Invention] As described above, according to the present invention, it becomes possible to effectively perform operation training of on-site operation equipment when operation from a remote monitoring control panel becomes impossible due to loss of control power,
A plant simulator with high training effect can be obtained.
