Abstract


With the basic realization of China 's power grid interconnection and strengthen gradually , taking into account the electricity market , renewable energy access , real-time online analysis and monitoring of the operational status of the large power grids is particularly important . Building online security analysis , monitoring , early warning and coordination control system , has become the development direction of the bulk power system dispatching operation technology . In response to this demand , in-depth study of visualization technology and computer power system in parallel computing technology involved in the design and realization of a \calculation and monitoring functions , the main work is as follows : 1 . system overall framework for the design work and graphics platform needs analysis : proposed comprehensive analysis system graphics visualization platform needed to achieve the function of the system results in display the layer and online computing layer achieve way ; 2 . achieve a common visual graphics platform for the visualization results on the basis of data and calculation of grid support: the application of power system visualization technology , design and generic visualization graphics platform for part of the display of the results of the software , which can use a variety of visual display , including grid based data visualization and computational analysis results visualization, alarm information prompts ; 3 . distributed parallel computing platform : Consider to online monitoring system with higher requirements for computing speed , online calculation software layer using a distributed parallel computing platform based on a database , computational analysis can perform multiple tasks at the same time , replacing the original serial computing model time-consuming the lack of long , improve the speed of the software online analysis and calculation . Development results has been tested and successfully used in Tianjin power grid online analysis and monitoring , and achieved good results . Practice has proved that through real-time online , the software can calculate the state of the power grid operation , accurate and timely response to the user , to meet the requirements of the line power system analysis software .
