Embodiment

[0039] The structure of the communication network of the present invention is as figure 1As shown, the power system master station 1 acts as the master station, and the power system simulator RTDS acts as the slave station. The connection between the power system master station 1 and the power system simulator RTDS realizes the LAN / WAN based on the TCP / IP protocol through the master station communication module DNP data communication. The function of this method is to realize data writing and reading between the EMS graphical interface of the master station and the RTDS power simulation system, and the completed functions include DNP protocol processing and real-time communication with the slave station (RTDS). When the slave station is an RTDS device, as a data communication mechanism between the master station and the slave station, it realizes reading and writing of analog and binary data between the master station and the RTDS. The master station modifies or updates the d...

Abstract

The invention provides a DNP protocol based online communication method of a power system simulator and a power system, which is characterized in that a power system master station (1) and the power system simulator RTDS realize TCP / IP protocol based LAN / WAN data communication via a master station communication module DNP. The data communication between the power system master station (1) and the power system simulator RTDS comprises data writing and reading between the power system master station (1) and the power system simulator RTDS. The completed functions comprise DNP protocol processing and real-time communication with the power system simulator RTDS. The invention can carry out researches on online fault analysis, accidents, sudden accident measure verification, accident pre-decision and the like of the power system on a real-time simulation system to enable the simulation running environment of the power system simulator to be closer to the actual process of the power system to facilitate the simulation results to be closer to the real grid so as to obtain more accurate analysis conclusion and more effective decision-making information.

Description

technical field [0001] The invention is an online communication method between a power system simulator and a power system based on a DNP protocol, and belongs to an innovative technology of the power system online communication technology. Background technique [0002] There is no real data exchange between the existing power system master station and the power system simulator RTDS, and it is difficult to conduct online fault analysis, accident research, verification of accident measures, and accident pre-decision-making on the power system on the real-time simulation system. It is also difficult to make the simulation operating environment of the power system simulator correspond to the actual process of the power system, so that the simulation results are difficult to approach the real power grid, and it is difficult to obtain more accurate analysis conclusions and more effective decision-making information. Contents of the invention [0003] The purpose of the present...
