Embodiment 1

[0033] The present invention provides a reliable control method for electric power telecontrol based on address self-verification, including:

[0034] Step S1, the master station and the factory station use the information object addresses or communication serial numbers in the routine information table to sequentially identify different remote control and remote adjustment objects, and the master station and the factory station each use the routine according to a preset mapping relationship. The remaining unused information object addresses or communication serial numbers in the information table are used to identify different remote control and remote adjustment objects in a non-sequential manner, and the remaining unused information object addresses or communication serial numbers in the conventional information table are called self-checking addresses. The original used information object address or communication serial number in the general information table is called the ...

Embodiment 2

[0086] According to another aspect of the present application, there is also provided an address self-verification based electric power remote reliable control system, including:

[0087] The master station is used to use the information object addresses or communication serial numbers in the regular information table to sequentially identify different remote control and remote adjustment objects, and use the remaining unused information object addresses in the regular information table according to a preset mapping relationship Or the communication serial number to non-sequentially identify different remote control and remote adjustment objects. The remaining unused information object addresses or communication serial numbers in the conventional information table are called self-checking addresses. The previously used information object addresses in the conventional information table or The communication serial number is called the sequence address. It establishes the local on...

Abstract

The present invention provides a reliable control method and system for electric power telecontrol based on address self-verification. The present invention does not modify the existing standard of the telecontrol communication protocol. It can solve the problem of wrong remote control caused by the factory station not being able to identify the address of the information object or the misplacement of the communication serial number in the telecontrol communication where different remote control and remote adjustment objects are identified by the address of the information object or the communication serial number.

Description

technical field [0001] The invention relates to the field of transmission protocols of telecontrol equipment and systems, in particular to a reliable control method and system for electric telecontrol based on address self-verification. Background technique [0002] Between the power dispatching automation master station system and the telecontrol communication server of the factory station, DL / T 634.5104 "Telecontrol Equipment and System Part 5-104 Transmission Protocol Using Standard Transmission Protocol Set IEC 60870-5-101 Network Access", DL476 "Application Layer Protocol for Real-time Data Communication in Electric Power System", DL / T 634.5101 "Telecontrol Equipment and System Part 5-101 Transmission Protocol Basic Telecontrol Task Supporting Standard", etc., are the most commonly used telecontrol communication protocols at present. In order to realize the upload of plant process quantity information such as remote signaling and telemetry, and the issuance of master st...
