Zhao Li · Power System Technology · 2014
To make full use of intelligent and visualization technology to process massive data generated in large-scale power grid rapidly and effectively,the visualization approach for power grid dispatching automation system to carry out real-time monitoring of main types of data is discussed,and a set of complete visualization solution scheme for power grid real-time monitoring is proposed.Following components are included in the proposed solution:the geographic map of power flow realized by 3-dimensional virtual reality technology and the power flow chart of the whole grid realized by splicing technology;the visualization of maintenance schedule based on the thinking of Gantt chart;load curves in power grid based on the thinking of K-line;the visualization of synthetic alarm realized by full 3-dimensional graphics;the visualization of data related to low-frequency oscillation occurred in power grid realized by full 3-dimensional graphics.The proposed solution scheme has been put into use in provincial and above dispatching and control centers and it operates steadily and reliably.The proposed solution scheme provides dispatchers more visual and intuitionistic manner and can find abnormal conditions in time during power grid operation and provide convenience for effective control and auxiliary decision-making.
