Study On The Development And Application Provincial And Regional Coordinated Intelligent Computing And Stability Analysis System

With the increasing scale of power grid,the structure is becoming more and more complex.The new voltage level and the emergence of power grid control equipment makes the operation of the power grid showing unprecedented complexity..At present,power grid security and stability analysis mainly rely on offline means,that is,using BPA,PSASP,PSSE and other computing softwares to irregular calculation by multiple sets of offline data files.In order to solve the power grid construction project is put into operation,the adjustment of equipment modification,equipment maintenance and operation mode of power grid brings the computational complexity of the problem,the establishment of the system,combined with the power grid construction project is put into operation,equipment modification,equipment maintenance and operation mode adjustment,strengthen the power grid structure management,and obtain the information generation and load operation mode from automatic system for quasi foundation provide real-time analysis calculation.This paper describes the province collaboration framework system,internal network security partition,system hardware architecture and software architecture.The security and stability of power system and analysis of the application of technology principle,including the design,management and development of the hierarchical model of the thermal stability limit calculation,correlation analysis,automatic maintenance flow balance calculation,based on the multiple fault set static security self generated,and the voltage stability assessment model and method..The power output,load and other operating mode information is obtained from the automation system,which provides a basis for real-time calculation and analysis.This system show "safety and stability guidelines","calculation standard","power grid operating standards" and other provisions of the standard on a unified platform in order to ensure the standardized calculation of professional personnel.The unified platform can improve the professional management of the county transfer system,realize the process management Monthly of security and stability analysis,annual operation mode analysis and rolling analysis of 2 ~ 3 years.The professional level of city and county dispatch get synchronous lifting.After the system realizes the standardization,the process and the fine management,intelligent operation mode analysis is implemented through a variety of means.All the calculation results can be optimized by a certain optimization program to obtain a satisfactory conclusion,which can be used to assist the personnel decision analysis.Through the in-depth analysis of the demand,limit of the automatic calculation,correlation analysis of maintenance,automatic flow balance and static security check based on multiple fault sets are used as the objective of optimization.
