Research On Dynamic Monitoring And Adjustment System Of Transmission Section Based On D5000 Platform

Dynamic monitoring of power grid is an important research content in power system.Through the dynamic monitoring of power grid and the use of auxiliary decision system,it is necessary to provide real-time grid information and decision-making plan for dispatchers,which will improve the control ability of dispatchers,Greatly enhance the efficiency of scheduling accident handling,and enhance the safe and stable operation of the system level.It is for this reason,the National Center has issued a "online safety and stability early warning system functional norms" and many other related documents,many power companies are currently building and research dynamic monitoring and emergency decision-making system.The purpose of this paper is to solve the problem of dynamic monitoring of the tidal current,and can make self-adjustment,so that the system power flow can be normal operation.This paper first introduces the architecture of the system platform,studies the standardization of the communication protocol required by the system,and then establishes the expert system database system model and the dynamic monitoring system model of the transmission section,and realizes the automatic identification,adjustment and cross-section flow Dynamic monitoring,and applied to the central power grid system.Finally,this paper uses the sensitivity analysis method,establishes the sensitivity matrix model,puts forward the reverse equalization matching method of the security correction strategy,and studies the automatic adjustment of the trend.Small-scale network structure,according to the power system network topology and system parameters,the application of matlab to the formation of the sensitivity matrix programming,and the sensitivity matrix as the basis for adjusting the power grid to determine the adjustment method to achieve the auxiliary operation of power grid decision-making function.In this paper,the IEEE118 bus typical power network system is used to verify the above model.The method is expected to be applied to the Central China Power Grid.
