Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides an operator with an emergency measure for handling an accident or failure in the operation of a primary substation (hereinafter referred to as a substation), which is a key part of a power supply system. The present invention relates to a driving support device for a substation, which is designed to guide a typical recovery procedure.

[0002]

2. Description of the Related Art Most of the conventionally known driving assist devices for substations of this type include information about the fact that an accident or failure occurs in the substation when the information is taken into the inference subsystem. Then, based on the online information, the inference necessary for driving is executed based on the captured information and the result is output to a human interface device equipped with a CRT to guide the operator.
It had only the actual operation mode that actually supports driving .

In addition to the actual operation mode as described above,
Equipped with a training mode in which simulated information on accidents / disorders at substations is generated to train the operator's treatment decisions, and this training mode and actual operation mode are manually switched by the operator etc. Is also known by some.

[0004]

Among the conventional driving support devices described above, the one having only the actual operation mode is used when the actual accident or obstacle requiring the urgency occurs.
Even if the contents of emergency recovery measures are displayed and guided on the RT, etc., not only the operator on the receiving side is likely to lack promptness but also the appropriateness in determining the corrective action. There is. On the other hand, with the training mode, operators are trained on a daily basis, so if an accident or obstacle actually occurs, as long as the fact can be sensed, it can be done quickly and accurately. Although it can be handled, since the mode switching from the training mode to the actual operation mode is manual, as in the case of an actual accident or failure during the training mode,
If the occurrence of an accident or obstacle cannot be detected, the driving support function in the actual operation mode does not work, and it takes time to respond.

[0005] The present invention has been made in view of the circumstances as described above, faster response operator, while have a training mode for suitable確化, during that training <br/> mode The purpose of the present invention is to provide a driving support device for a substation that can reliably perform the driving support function in the actual operation mode even if the operator does not detect the actual accident or failure. .

[0006]

Means for Solving the Problems] To achieve the above object, the driving support device of substation according to the present invention, accidents and failure information generated in the substation through a relay board and input unit
Preparative interrupt, reasoning subsystem unit and to perform reasoning required to operate by the information taken this reasoning subsystems
Output the inference result in the system section to guide the operator .
For the actual operation with the human interface device that
And online system, the simulation information of accidents failures in substations to input to the inference subsystem unit, a training to execute the inference by the simulation information, and for outputting the inference result to the human interface device of use
Offline mode and both line system operation modes
Is configured to be switchable to each other, and a data control unit that monitors online system information during the training mode in the offline system, and when this data control unit receives online system accident / fault information, Online luck from training mode
And an operation mode switching means for automatically switching to the operation mode.

In the driving support device for the substation as described above
There are, the reasoning subsystem unit has a line system and off-line system data controller and the inference section to each other, respectively, when the data control unit of the online system receives accidents and failure information of the online system, offline It is preferable to provide a stopping means for automatically stopping the operations of the data control section and the inference section of the system.

Further, it is preferable that the operation mode switching means is set so that the switching operation is performed within 5 seconds when the online data control unit receives the online accident / fault information.

[0009]

SUMMARY OF] A drive assistance device of the substation of the present invention having the above structure, in addition to the actual operational mode of the online system, offline
In the event of an accident or failure , an in-system training mode is provided to infer simulated information on an accident or failure at a substation and to output the results to a human interface device to provide training to operators. It is possible to carry out regular training to give operators a prompt response. Moreover, online
Online system information even during training Gumodo in-system has been cut off is monitored at all times, online
If an accident or failure occurs in the system , training
Automatically switching instead from grayed mode in practical mode of the online system, operation support functions in production mode is exhibited.

Particularly, when the online data control unit receives the online accident / fault information, when the operations of the offline data control unit and the inference unit are automatically stopped, or when the online data control is performed. When the department receives the online accident / fault information and sets it to switch within 5 seconds, the driving support function in the actual operation mode for the actual occurrence of the accident / fault should be executed earlier. You can
