| Abstract: |
| Aiming at the computing difficulty caused by the high-dimensional adjacency matrix in online simulation system for large scale power network，a vector flow tracking algorithm with real-time simulation is proposed. The topology vector flow graphic is defined based on the real-time data fusion model and SVG vector release format expansion，the attribute domain model of topology vector is constructed，and the flowchart of the topology vector flow graphic tracking algorithm is designed and implemented. With the optimization of computing logic expressions and idiographic tracking for H-bridge topology vector flow graphic， the computational efficiency is improved by 40 %. Online simulation of feeder blackout is carried out with the proposed algorithm for test network，results show the accuracy is 100 %，which proves the presented algorithm meeting the demands of power supervisory system for online simulation and application. |
