Method of electric power automatic system for measurement and modeling based on CIM

Abstract

The invention discloses a method of an electric power automatic system for measurement and modeling based on CIM and belongs to the technical field of computer-aided design specially used for electricpower system modeling. The method disclosed by the invention is characterized in that an electric power system wiring diagram is drawn according to engineering practice, electric power model creationbased on CIM is carried out, voltage measurement of a bus section, analog quantity measurement of a switch and measurement of remote communication data such as state of the switch are created according to the engineering practice, and measurement of analog quantities such as power and current of the switch is mapped to equipment such as a circuit, a transformer winding, a load, a generator, a capacitor and an electric reactor which are connected with the switch. The method disclosed by the invention has the advantages that measurement modeling flexibility can be improved, and solves the problem that power and current measurement values of the equipment such as the circuit, the transformer winding, the load and the generator are difficult to acquire by electric power system simulation andcalculation software after measurement of the power and current is established on the switch.

Description

technical field [0001] The invention discloses a CIM-based measurement and modeling method for a power automation system, and belongs to the technical field of computer-aided design especially for power system modeling. Background technique [0002] The CIM (Common Information Mode) of IEC61970 and IEC61968, that is, the public information model, is an international standard for power system data sharing formulated by IEEE (Institute of Electronics and Electrical Engineers). CIM covers various objects commonly used in power analysis and control including power components, plants and stations. As an international standard, CIM has been actively supported by power companies and developers in various countries. At present, CIM has been applied to various application systems such as SCADA, network analysis, and EMS. In China, the National Electric Power Dispatch and Communication Center has organized several CIM interoperability experiments, providing an experimental basis for ...

AI Technical Summary

Problems solved by technology

The power system simulation and calculation software uses the "busbar-branch" model, that is, the calculation model obtained through network topology analysis is used, and the switchgear is excluded from the calculation model. Therefore, if the power, current, etc. Associated with the switch, it will cause difficulties for power system simulation and calculation software to obtain power and current measurement values ​​of lines, transformer windings, loads, generators and other equipment
