Description

TECHNICAL FIELD The present invention relates to a digital protective relay device, and more particularly to a setting value control device.

(Prior Art and Problems) A digital protective relay device generally incorporates a large number of relay elements (or relay functions).

The number of extra units required for protection calculation by a protection processing device such as the microcomputer 4 is 1. Several relays are required for one relay. Therefore, as the number of relay elements increases, the number of necessary settings for protection nets and electrical equipment increases. child,
, these setting values are the internal values of the protection, the protection, and the
Those stored in memory and required once for each 3% retention calculation are read out to the logic element during the judgment process. ,,.

This 7. ,, To confirm the setting value that is created in the ninth place, OR'l' from the memory area.
On the display of the table, water device, etc., 1. 5 things to read out,
11. Individual settings.

In the method of performing readout and display processing, one operation is required for each set value, and an enormous amount of time and operations are required for inspection and the like to display and confirm the failure of all set values.

In addition, with the method of displaying setting values all at once or group display processing, other setting values are displayed together to confirm one setting value, making it difficult to find the required setting value on the display. There is a risk.

In addition, in the 1-individual display, one setting value is switched and displayed for each operation, so in order to compare and contrast the setting value being displayed with other setting values, it is necessary to know other setting values by other means. It takes time to compare. For example, three set values xl + xl
+ In order to confirm the magnitude relationship of "*", a means for knowing "x+Xze" with respect to x3 currently displayed is required.

(Object of the invention) The present invention has been made in view of the above-mentioned circumstances.
It is an object of the present invention to provide a processing device that makes individual confirmation and comparative confirmation of values reliable and easy.

(Summary of the Invention) The present invention has two processing systems, one for individual confirmation of set values and one for batch recording, and the individual confirmation uses a method of individual fingerwax operation for each set value as in the past, and the batch recording requires one processing. It is characterized in that each setting value is automatically recorded in the JI [JI] by setting value group designation operation.

(Embodiment) The figure is a set value confirmation flowchart showing an embodiment of the present invention. By operating the setting value confirmation command switch, the processing device of the setting section enters the confirmation mode, and first asks the operator for individual confirmation and batch recording of the setting values (step StL. ) and batch recording (step days 8 to □512).

For individual confirmation, wait for the operation of the setting value code you wish to display (
Step S2) Displays the set value specified by inputting the code on the display (Step 83) Waits for the operator to confirm the displayed set value (Step S2)
・4□After this confirmation operation, it is determined whether or not there is a set value for the next display ``desired'' (step s5), and if there is, the process returns to wait for the code operation (C52).

If there is no display, notify the end of the display (λ' tab 86).
), all display contents are erased (step 87).

In this individual confirmation process, confirming one setting value requires at least inputting and confirming the setting value code, and makes comparison with other setting values difficult.
- In batch recording, a batch recording command waits for one setting value group designation operation (step SS).

This operation is performed by specifying a code that can specify one setting value group 7' (including the entire group), such as a setting value group code or the first setting value within the group. The first set value in the group or one of the set values of the specified code is recorded in a recording device such as a printer by the floop designation operation (step s9), and there is no □ recording end operation (step 810). When the recording of the group in the gate value memory is not completed or the recording of all set values □ is not completed (step B11), the process returns to step day 9 to record the next set value. When there is an operation to end recording in step 810, end processing is performed (step 812).

In this batch recording, setting value group constant or all setting value t
When forming one group, by specifying all setting values, the setting values belonging to the group or all setting values can be automatically recorded until the recording end specification is specified, or all of them can be automatically recorded, eliminating the need for the operator to specify individual codes. A record of the set values can be obtained.

Furthermore, when it is necessary to correct errors or change settings to confirm the setting values, in the case of individual confirmations, you can enter the setting value change processing mode by performing the step Kanakura, which receives change commands at the confirmation stage; By including a step of receiving a change command in the loop processing of steps 89 to 11, a change processing mode can be entered, and the set value can be changed in any case.

(Effects of the Invention) According to the present invention, in addition to the individual setting value confirmation function Ω, a batch recording function is provided, so that in the setting value confirmation work, the matching check operation between the setting value list and the currently operating setting value is performed simultaneously. Recording specification eliminates the need to specify individual codes for setting values, and the confirmation work can be performed sequentially by combining the list order and the recorded setting value order. Furthermore, setting values can be easily compared and confirmed. It has an excellent effect in reducing work and eliminating omissions in checking.
