Embodiment Construction

[0028] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like figure 1 As shown in the figure, the main station is located in the protection main unit located in the safety zone I of the power system. The main station sends remote operation commands to the protection main unit, and the protection main unit communicates with the protection device in the station through the IEC61850 specification; the automatic management steps of the protection device setting value are:

[0030] 1) When the master station needs to read the fixed value of the target fixed value area, it first sends a message to the protection main unit to change the edit fixed value area to the target fixed value area number;

[0031] 2) After receiving the message from the master station, the protection main unit instructs the protection device to modify the editing fixed value area code to the target fixed value are...

Abstract

The invention discloses a protection device constant value automatic management method based on fuzzy matching, and relates to the field of power system scheduling automation. According to a conventional transformer substation, the constant value cannot be modified remotely, a worker is needed to perform constant value modification in the field, and disadvantages of low efficiency, high maintenance cost, long maintenance time and easy mistake occurrence exist. The method of the invention is characterized in that a master station is provided with a protection main unit located in a power system safe I region, a remote operation command is issued by the master station to the protection main unit, and the protection main unit is in communication with station protection devices through the IEC61850 specification; and protection device constant value automatic management is performed. According to the technical scheme, the protection main unit is added, the constant value modification control function can be realized, the advantage of reliable operation can be realized, adjustment and control integration of the production operation department can be facilitated, the accident processing scheme can be made fast, the production scheduling and management decision making can be optimized, the protection device constant value can be modified timely, and the accident loss of the power grid can be reduced.

Description

technical field [0001] The invention is applied to the field of power system dispatch automation, and in particular relates to a method for checking the constant value of a control system in a power system. Background technique [0002] Relay protection and safety automatic devices are important barriers to ensure the safe and stable operation of power systems. The online monitoring of secondary equipment realizes automatic collection, analysis and processing of secondary equipment information such as protection and safety automatic devices, and provides information support for power grid dispatchers to deal with power grid accidents. Realizing the remote monitoring of relay protection equipment is beneficial for the production and operation department to realize the integration of regulation, quickly make an accident handling plan, optimize production scheduling and management decisions, prevent the expansion of accidents caused by incomplete information and misjudgment, an...
