ONLINE REAL-TIME LOOP CLOSING METHOD BASED ON INTEGRATION OF MAIN NETWORK AND DISTRIBUTION NETWORK

摘要

Disclosed is an online real-time loop closing method based on integration of a main network and a distribution network. The online real-time loop closing method is characterized by comprising the following steps: S01: conducting network modeling; S02: conducting main network and distribution network measuring and reading and acquiring initial section data of loop closing load flow calculation; S03: conducting loop searching and phase verification; S04: conducting loop closing load flow calculation; and S05: conducting loop closing risk evaluation. Models and real-time data are online acquired in an EMS and a DMS respectively, calculation results are interacted through an information exchange bus, and then loop closing load flow calculation units or programs running on a PAS server of the DMS and a PAS server of the energy management system can simultaneously acquire the models and the data of the main network and the distribution network for alternate iterative calculation, so that calculation accuracy is greatly improved, and the loop closing load flow calculation units or programs can conveniently run and can be conveniently maintained.
