Embodiment Construction

[0033] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] The invention discloses an embodiment of a remote checking method for the fixed value of a relay protection device. The protection device provides the setting file, the setting setting system provides the reference file, and the dispatching master station obtains the setting file and the reference file from the relay protection device and the setting setting system respectively, and compares them to obtain the setting check result.

[0035] The operation of dispatching the master station to obtain the fixed value file from the relay protection device specifically includes the following steps:

[0036] The dispatching master station responds to the setting value verification request and issues a setting value file call command;

[0037] The relay protection device responds to the call command of the setting fil...

Abstract

The invention discloses a relay protection device fixed value distant checking method. A fixed value of a relay protection device circulates in a system in a file mode, a fixed value file is providedby the relay protection device, a reference file is provided by a fixed value setting system, and the fixed value file and the reference file are obtained by a dispatching master station from the relay protection device and the fixed value setting system respectively to compare to get the fixed value checking result. The method is advantaged in that mapping works of various communication links ofa fixed value model are simplified, artificial intervention links are reduced, system complexity is reduced, and system reliability is improved.

Description

technical field [0001] The invention relates to the field of comprehensive automation of power system substations, in particular to a method for remotely checking the fixed value of a relay protection device. Background technique [0002] The fixed value is the basis for the correct action of the relay protection device. The correctness and adaptability of the fixed value play a very important role in the correct action of the relay protection and the safe operation of the power grid. With the widespread promotion of unattended substations and the improvement of automatic operation level, the demand for remote verification of relay protection device settings by the dispatching master station through the power dispatching data network is increasing. [0003] At present, there are two ways to realize the fixed value verification of relay protection devices, one is the traditional manual local verification, and the other is remote verification based on the information point mod...
