Embodiment Construction

[0018] see figure 1 , figure 1 It is a schematic flow chart of the method for collecting station domain protection data based on the telecontrol device in the present invention.

[0019] The station domain protection data collection method based on the telecontrol device includes two parts:

[0020] S101. The telecontrol communication device collects station domain protection data in the station, encapsulates the station domain protection data into a data message according to the IEC104 communication protocol, and sends the data message to the station domain protection control device through Ethernet;

[0021] S102. The station domain protection control device receives the data message, analyzes the data message according to the IEC104 communication protocol, acquires corresponding station domain protection data, and writes the station domain protection data into an internal shared memory.

[0022] In the station domain protection data acquisition method based on the telecon...

Abstract

The invention provides a method and system for collecting substation area protection data based on telecontrol equipment. The method comprises the steps that the telecontrol communication equipment collects the substation area protection data in a station, the substation area protection data are encapsulated into data messages according to an IEC104 communication protocol, and the data messages are sent to a substation area protection control device through the Ethernet; the data messages are received by the substation area protection control device and are analyzed according to the IEC104 communication protocol, and the corresponding substation area protection data are obtained and are written in an internal shared memory. A primary device and a secondary device for collecting information are prevented from being added to a transformer substation, and implementation cost for substation area protection is lowered; the substation area protection control device can efficiently acquire data information from the telecontrol communication equipment at high speed, and the change on the internal structure of the transformer substation and the influence on the operation of the transformer substation are avoided.

Description

technical field [0001] The invention relates to the technical field of electric power relay protection, in particular to a method and system for collecting station domain protection data based on a telecontrol device. Background technique [0002] Traditional relay protection only reflects the limited operating status of a certain point or a local area of ​​the power system, and cannot reflect the safe operation level of a larger regional power grid. Regional protection is based on multi-point electrical information, which has natural principle advantages compared with traditional "point" and "line" methods. Regional protection is generally divided into three layers: equipment layer, substation intermediate layer, and regional decision-making layer. The second layer is the station domain protection of the middle layer of the substation, which performs the main protection and backup protection functions within the scope of the substation, and is responsible for the real-time...
