Embodiment Construction

[0022] 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.

[0023] The station domain protection data collection method based on the telecontrol device includes two parts:

[0024] 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 IEC 104 communication protocol, and sends the data message to the station domain protection control device through Ethernet;

[0025] S102. The station domain protection control device receives the data message, analyzes the data message according to the IEC 104 communication protocol, acquires corresponding station domain protection data, and writes the station domain protection data into an internal shared memory .

[0026] In the station domain protection data acquisition method based on the tel...

Abstract

The present invention provides a method and system for collecting station domain protection data based on a telecontrol device, comprising the steps of: a telecontrol communication device collects station domain protection data in a station, and encapsulates the station domain protection data into a datagram according to the IEC104 communication protocol text, and send the data message to the station domain protection control device through Ethernet; the station domain protection control device receives the data message, analyzes the data message according to the IEC104 communication protocol, and obtains the corresponding station domain Protect data, and write the station domain protection data into an internal shared memory. The invention avoids the addition of primary and secondary devices for collecting information in the substation, reduces the implementation cost of station domain protection; can realize the efficient and high-speed acquisition of data information by the station domain protection control device from the telecontrol communication device in the station, and avoids changing the internal structure of the substation and operational effects.

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...
