| In recent years, with the xinjiang power grid spatial scale is constantly expanding,theoperation state of power grid becomes more and more complex, the role of the online securityearly warning and auxiliary decision system of the xinjiang power grid becomes more andmore important, the reliability of the system is the guarantee of the safe and stable operationof power grid, Data source of high quality is the system give full play to the role of thepremise, and the quality of the data source depends on the effective combination of three parts,which is the power network construction and state estimation and data integration, Therefore,the study of grid network construction, state estimation, data integration of these three parts isvery important and meaningful work.Firstly, for the online security early warning and auxiliary decision system of xinjiangpower grid is studied, and the function of the software platform support system are analyzed,at the same time, the function of the application of the system are analyzed. Secondly,according to the characteristics of the xinjiang power grid, the construction scheme ofxinjiang power grid network are studied, and the proposed scheme has carried on thesimulation analysis by PSASP software the scheme proposed by PSASP software, and verifythe feasibility of xinjiang power grid network construction scheme, Xinjiang power gridnetwork construction scheme greatly simplifies the scale of network building. At the sametime, a method of Improve the qualified rate of state estimation debug was put forward, And anew ring circuit parameters estimation based on matrix computation practical method and thecorresponding verification can improve the precision of estimation of power grid. Finally,studied Xinjiang power grid online security early warning and auxiliary decision system dataintegration solution, and presents an improved data integration solution based on thecharacteristics of Xinjiang grid. |
