Embodiment Construction

[0031] Research and analyze the key communication indicators containing time series for the protection and control information flow transmission, and map them into multiple sets of end-to-end communication parameters, import the communication parameters obtained in OPNET in the MATLAB / Simulink simulation platform, and use From Workspace A module that reads data from a file in a computer, this module reads data from a file on the target computer's hard disk, and uses S-function to programmatically output communication parameters. Therefore, the power communication network built in OPNET is equivalently mapped into multiple simple end-to-end communication channels, and finally the multiple simple end-to-end communication channels are embedded in the power simulation without bias in MATLAB.

[0032] The purpose of communication is to realize the transmission of information, whether it is a complex communication network or a simple end-to-end communication, it is the process of tra...

Abstract

The invention discloses an end-to-end model mapping electric power communication hybrid simulation method, which belongs to the technical field of electric power communication. The purpose of the present invention is to start from the overall research scene and research object of electric power communication hybrid simulation in the OPNET simulation platform, according to the actual requirements in the communication network between the dispatching center and the station end, to analyze the connection between the dispatching center and the station end in the case of smart grid The communication network system and protection control information flow data are modeled and simulated, the appropriate modules and parameter statistics are selected, and the communication model is built and simulated. The end-to-end model mapping is a hybrid simulation method for power communication. The steps of the invention are: building a communication model, extracting and recovering parameters, and mapping of an end-to-end communication model. The invention maintains the dynamic characteristics of the two systems and has low cost, so it has wider application prospects, realizes embedded power simulation without deviation in communication simulation, and effectively solves the time synchronization problem of the two simulation platforms.

Description

technical field [0001] The invention belongs to the technical field of electric power communication. Background technique [0002] With the development of smart grid and energy Internet construction, the dependence of power system on high-speed and reliable information communication and the development trend of integration between power and information, hybrid simulation of power communication has become a research hotspot in related fields. There are essential differences in mathematical models between power systems and communication systems. There is still a lack of efficient and reliable unified simulation tools. The existing simulation methods mainly include three methods: simultaneous simulation, non-real-time simulation and real-time hybrid simulation. [0003] The main idea of ​​the simultaneous simulation scheme is to build a complex power and information communication composite system model in a single simulation tool. This method builds the communication (or power...
