Transmission method of electric power system remote control command

Abstract

The invention discloses a remote control command transmission method for a power system. The method comprises the following steps of acquiring a remotely-controlled object code of a remotely-controlled object from a remote control list after an instruction of sending a remote control command is received; generating the remote control command, wherein the remote control command comprises an information object address and the remotely-controlled object code; sending the remote control command to a station terminal. According to the remote control command transmission method for the power system disclosed by an embodiment of the invention, a risk of remote control by mistake is prevented, the hidden problem of misoperation that the power system transmits the remote control command is eliminated, and the safety of power grid operation is improved.

Description

technical field [0001] The invention relates to the technical field of electric power information, in particular to a method for transmitting a remote control command of a power system. Background technique [0002] In the current power system application, when it comes to the remote control of the master station to the station terminal, it is mostly carried out by sending remote control commands, and the telecontrol protocol IEC101 (International Engineering Commission, International Electrotechnical Commission 101 is the remote Dynamic dedicated line protocol) and IEC104 (International Engineering Commission, the telecontrol network protocol formulated by the International Electrotechnical Commission 104) to send remote control commands. The remote control protocol IEC101 and IEC104 use the same remote control application and service data unit ASDU (Application Service Data Unit, application and service data unit) 45 (single-point remote control) and ASDU46 (two-point remo...

AI Technical Summary

Problems solved by technology

The remote control protocol IEC101 and IEC104 use the same remote control application and service data unit ASDU (Application Service Data Unit, application and service data unit) 45 (single-point remote control) and ASDU46 (two-point remote control), including remote control points in ASDU45 and ASDU46 No., the remote control point number is used as the only factor to distinguish the remote control object, and it is transmitted in the form of information object address. Once there is an error in the association between the main station graphic and the remote control point or the remote control point of the station end system does not correspond to the main station system, it will occur. False remote control, thus seriously affecting the safety of power grid operation

For example, when the remote control point associated with the remote control object at the master station is wrong, if the remote control point corresponding to a certain device should be point 1, but the automation personnel accidentally set the remote control point of the device to point 2 at the master station, when When sending a remote control command to the device, the station end will control (open or close) the device corresponding to point 2 after receiving the remote control command; the remote control point associated with the remote control object at the master station is correct, but at the opposite station end the remote control point is correct. When the sequence of the remote control point list at the station end is misplaced or confused during the maintenance of the forwarding table, the corresponding relationship between the remote control point at the station end and the remote-controlled device will be wrong. Selected remote control equipment often occurs false remote control
