Embodiment Construction

[0028] The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings of the description.

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

[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 edited fixed value area to the target fixed value area number;

[0031] 2) After the protection main unit receives the message from the master station, it commands the protection device to modify the edited fixed value area code to the target fixed value area code;

[00...

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 in the field of electric power system scheduling automation, and in particular relates to a method for checking the fixed value of the control system in the electric 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 the automatic collection, analysis and processing of secondary equipment information such as protection and safety automatic devices, and provides information support for power grid dispatching and operation personnel to deal with power grid accidents. The realization of remote monitoring of relay protection equipment is beneficial to the production and operation department to realize the integration of control, quickly make accident handling plans, optimize production scheduling and management decisions, prevent the expansion of accidents caus...
