Research On The Data Visualization Of Power System’s Transient Stability Based On CIM Model

The complexity of power grid and the continued expansion of the scale provide a strongsupport to the construction and the development of China’s economy. In order to ensure thesafty and stablity of power grid, production scheduling and substation operation managementhave brought great challenges to us. Establishing and improving the safe monitoring whichdefenses the grid safty and stablity, has become our country’s pressing matter of the moment.However, the current real time stability analysis system of power grid in china, especially forthe transient stability analysis, can not calculate optimistically. Because of the large amount ofdata input and the complexity of calculation, the existing servers used can not calculatetransient stability results timely. The data format of stability analysis system is varietious. Themodel of it is not uniform, and the integration between the system upgrade and the gridbecomes more difficult. Therefore, establishing imminent and real-time transient stabilityanalyze platform which according to IEC61970standard is very important.In this paper, the author firstly focused on the complicated data formats and the disabilityof basic data merging of the power system’s transient stability analysis and then gave severaldata models and those data formats for components of transient stability analysis used, whichare based on CIM of data to solve this problem. Secondly, the author focused on the problemthat the efficiency of multi-node transient stability analysis calculations was very slow. Theauthor used Hadoop technology and implemented the concurrent algorithm of transientstability analysis to solve the problem of low efficiency. And then the author verified thehigh-efficient of it through doing contrast experiments. Finally, the author gave a systemdesign and implement method to solve the problem of data visualization for transient stabilityanalysis, based on the stability analysis in multi systems cannot real-time display calculateresults, using HBase database storage technology. And then the author verified the usability ofthis implementation through using other paper’s actual data.
