Problems solved by technology

[0003] The disadvantage of this original inspection method is that it is inefficient, and it is difficult for setting calculation specialists to verify the boundary value in real time
On the other hand, manually inputting the boundary value is a heavy workload and prone to errors
A large number of manual verification methods are relied on, and the accuracy is difficult to guarantee

Embodiment Construction

[0034] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0035] Such as figure 1 As shown, the boundary equipment relay protection fixed value automatic verification method of the present invention includes:

[0036] Step 1: Determine a certain device in the power system and find its adjacent boundary devices;

[0037] Step 2: Search whether there is the fixed value data of the boundary equipment in the boundary equipment relay protection fixed value shared library, if it exists, then call the boundary equipment fixed value data from the boundary equipment relay protection fixed value shared library; otherwise, trigger Calculate the relay protection setting value of boundary equipment;

[0038] Step 3: Verify the calculated boundary equipment relay protection setting, confirm that the boundary equipment relay protection setting is correct, and write it into the boundary equipment relay protection setting shared l...

Abstract

The invention discloses an edge device relay protection fixed value automatic verification method and system, wherein the method comprises the steps of: 1, determining one device in an electric power system, and searching for an edge device adjacent to the device; 2, retrieving an edge device relay protection fixed value shared database for determining whether fixed value data of the edge device exists, if yes, obtaining the fixed value data of the edge device in the edge device relay protection fixed value shared database, and if not, triggering the calculation of the edge device relay protection fixed value; and 3, verifying the calculated edge device relay protection fixed value, and writing the edge device relay protection fixed value into the shared database after determining that the edge device relay protection fixed value is correct.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a method for automatically checking the fixed value of a boundary equipment relay protection and a system thereof. Background technique [0002] Once a fault occurs during the operation of the power system, the faulty component must be removed quickly and selectively to avoid personal injury or damage to electrical equipment, and the protection device that completes this function is a relay protection device. Among them, the most basic requirements of relay protection are selectivity, quick action, sensitivity and reliability, and at present, the verification of the relay protection setting value of the boundary equipment between various power companies is basically in the state of manual verification. The setting calculation specialist manually inputs the relay protection setting value of the boundary equipment into the setting calculation system, and then ca...
