Programmed Control System and Method for Master-Substation Based on General Service Protocol

Abstract

The invention discloses a master-substation programmed control system and method based on a general service protocol. The system includes a power dispatching master station and a substation of a substation. The measurement and control device, protection device and video inspection system connected to the server, the power dispatching master station communicates with the substations in turn through the service management center and service agent, and the intelligent gateway or monitoring server provides programmed control services; the power dispatching master station uses It is used to call the programmed control service through the general service protocol and issue the programmed control operation request; the substation of the substation is used to receive the programmed control operation request from the dispatching master station, and realize the five-defense service, operation ticket service, video service, The response of the measurement, control, protection and control service obtains the feedback information, and responds the feedback information to the power dispatching master station. Beneficial effect: the work efficiency and safety of the programmed control of the main and sub-stations are improved.

Description

technical field [0001] The invention relates to a programmed control technology, in particular to a master-substation programmed control system and method based on a general service protocol, belonging to the technical field of electric power automation. Background technique [0002] As we all know, programmed control technology has been very important in the advanced application of power system, and the perfection of programmed control technology in main and substations has greatly promoted the development of unattended or few-attended substations. [0003] The basic process of the traditional master-substation program control technology is to send the instructions of the master station to the monitoring server in the sub-station through the telecontrol equipment in the sub-station, complete multiple steps at one time according to the specified operation ticket, and simultaneously perform the five-proof locking logic or other control conditions. [0004] With the rise of S...

Problems solved by technology

[0005] The programmatic control technology of master and substations has not been standardized yet, and the implementation of this technical function by various manufacturers is flourishing. This has caused difficulties in the unified monitoring of the master station, and at the same time, it cannot promote the implementation of the programmatic control technology of master and substations in most parts of the country.

[0006] At present, there are many kinds of secondary equipment in the domestic power system, serious professional division, and the formation of separate information islands. This not only causes duplication and waste of system construction, but also is not conducive to the common development of programmed control technology and other advanced applications.

In addition, the existing programmatic control of the main substation is not yet perfect. On the one hand, there are potential safety hazards;
