Abstract

The invention discloses a flexible power distribution network real-time simulation information modeling method, which comprises the following steps of carrying out integral modeling by taking a real-time simulation platform as an IED, taking each simulator as logic equipment, decomposing specific functions of a flexible power distribution network system according to a four-remote function throughan object-oriented method, and establishing corresponding logic nodes; converting the data in a UDP format of the simulation platform into data in an IEC 61850 standard format through re-encapsulationand object mapping of the data; realizing model and service mapping from ACSI to MMS through an IEC 61850 server; starting an MMS service according to the corresponding mapping, and after receiving the data transmitted by the simulator and finding a corresponding IEC61850 mapping node, modifying the data into a corresponding data object attribute, so that the IEC61850 client or the IEC61850 equipment can successfully read and write the related analog quantity and digital quantity information of the power grid model in the simulator, and the functions of remote measurement, remote signaling, remote control and remote regulation of partial data in the flexible power distribution network model are realized.

Description

technical field [0001] The invention relates to a real-time simulation information modeling method of a flexible distribution network, which belongs to the technical field of intelligent distribution network equipment. Background technique [0002] In the traditional distribution network, there are problems such as poor interoperability between primary and secondary equipment, difficulty in sharing information in real time, poor system scalability, and many potential safety hazards in secondary cable loops. In order to ensure the economical, safe and stable operation of the power grid, the IEC TC 57 committee has published the IEC 61850 series of standards, aiming to standardize the open information exchange and interoperability functions provided by different equipment in the substation. With the in-depth research on microgrid, distribution network automation, electric vehicles, wind power generation and distributed power supply, the IEC 61850 series standards have begun to...
