DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital protection relay for detecting an accident in a power system, restoring the accident, and preventing the spread of the accident.

[0002]

2. Description of the Related Art FIG.
Vol. 1, No. 1, is a block diagram showing a conventional digital protection relay device shown on page 131 of "2nd generation digital relay" issued in 1994, where 1 is a voltage and a current from a system. A main relay that performs a relay operation using this digital amount, performs a sequence operation based on the relay operation result, and has the same function as the main relay 1. 1 is a fail-safe relay functioning as a backup.

[0003] Reference numeral 3 denotes a human-machine interface unit for inputting / outputting information to / from the main relay 1 and the fail-safe relay 2, display control, and operation control. 4 denotes input of display information from the main relay 1 and the fail-safe relay 2 and main control. An input / output unit for outputting information set for the relay 1 and the fail-safe relay 2, a display unit 5 for displaying display information from the main relay 1 and the fail-safe relay 2 input to the input / output unit 4, and a display unit 6 This is an operation unit integrated with a display unit 5 for switching display of information to be displayed and changing settings of the main relay 1 and the fail-safe relay 2.

Next, the operation will be described. Operations such as setting values of the main relay 1 and the fail-safe relay 2, changing set values, and changing display contents are performed by referring to display information displayed on the display unit 5 of the human-machine interface unit 3 while operating the operation unit 6. Is performed by operating. The information displayed on the display unit 5 is extremely complicated and enormous. In a general protective relay device, a graphic display is used to divide the screen into a plurality of screens and display the divided screens with figures and characters.

[0005]

Since the conventional digital protective relay is constructed as described above, the display unit 5
Are only the information accumulated by the protection relay device during its operation and the set values and setting values required for the operation of the protection relay device. Further, the operation is only the operation of changing the set value and the set value of the protection relay device and the operation of switching the display screen.

Therefore, a separate software generation tool is required for the software of the protective relay device, and the necessary software is generated by performing programming and compilation on the tool. The generated software is once written into the storage unit of the hardware of the protection relay device using a dedicated writing tool or the like. Generally, a protection relay device composed of a plurality of hardware requires an operation of writing for each piece of hardware. The operation verification of the written software can be performed only by actually operating the protection relay device. Also, what kind of function the software once written has and what settings have been made There was a problem that it could not be easily grasped by anyone other than specialized engineers.

[0007] For example, as a specific example, when it is necessary to write necessary software to change the function of a protective relay device in operation, a specialized engineer programs and compiles the software. Generate
Remove the relevant hardware from the already assembled protection relay device, write the software to the hardware with a dedicated tool, reassemble the hardware into the protection relay device, and finally, a specialist engineer verifies the operation. Since it needs to be performed and requires an extremely large number of procedures and specialized work, there is a possibility that the work procedure is erroneous and a human error occurs in programming, compiling, and the like. Further, when a new trouble occurs during the operation verification, it is necessary to repeat the above-described procedure, and it may take a long time until the device operates normally.

[0008] As another problem, a digital protection relay device that handles advanced and large amounts of data requires various types of hardware corresponding to the digital protection relay device. It is necessary to execute the software after writing necessary software in all the hardware by aligning the hardware described above, so that it takes a very long time to complete the digital protection relay device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object to enhance the operation and setting functions of a human-machine interface unit. In addition, by adding a software generation function to the human interface section and a protection relay simulation function, it is possible to reduce specialized work such as programming and debugging in the software production of digital protection relays and work procedures.・ Dramatically improve the productivity and reliability of digital protective relays by facilitating the contents, and quickly and highly reliable for failures and functional changes of digital protective relays without the need of specialized engineers. The purpose is to be able to respond to.
