Protected object-oriented automatic modeling and real-time information joint processing method

Abstract

The invention discloses a protected object-oriented automatic modeling and real-time information joint processing method, which is characterized by comprising the following steps that: 1) in an EMS system, a main station system automatically establishes a secondary equipment model of the system by calling protected substation configuration information; 2) the system establishes a complete secondary equipment relationship model; 3) the system establishes a controlled relationship model between the secondary equipment and a controlled object; 4) the main station system automatically performs information instantiation on protected device configuration classification information; 5) the system automatically establishes a corresponding relationship between a telecontrol protective hard node signal and the protected device configuration information; 6) the system implements warning suppression for the same real-time information forwarded from a telecontrol channel and a protective channel; and 7) a switch trip property is positioned, and whether the switch trip is a real accident trip is judged. The method effectively ensures the accuracy of model maintenance, prevents manual configuration error of the secondary system main station, and improves the level of the automatic system.

Description

Technical field [0001] The invention relates to a method for automatic modeling and real-time information joint processing of electric power systems for protection objects, and belongs to the technical field of electric power systems. Background technique [0002] It has been a long time since the development of domestic power system dispatching automation. The EMS power grid energy management system has developed to a new level. The technology is becoming more and more mature, the application is more and more extensive, and the system's monitoring and management of primary equipment is becoming more and more perfect. In the power system, as one of the most important subsystems of the EMS energy management system, the SCADA system is mainly responsible for the monitoring and control of primary equipment. It not only provides important monitoring methods for dispatching and centralized control personnel, but also prepares for advanced applications of the power system The primary e...

Problems solved by technology

[0005] In order to reduce operating costs, increase labor productivity, increase safety and economic benefits, and improve the level of modern control and management of power grids, electric power companies have adopted a large number of unattended substation design schemes. With the increase of unattended substations, the work done by station personnel in the past , need to be completed by the remote master station system, such as setting value modification, protection device soft pressure plate switching and switching, etc., but there is still a lack of this joint processing method for realizing remote control and protection real-time information
