Based On Minimum Information Base Grid Data Integrated Application System

With the progress of electrically industry, the power system technology based on the modern computer and communication technology is improving rapidly, and the information system construction is more and more important. The merit of information system is rest with the integration of the information. The higher the integration degree is, the bigger the value in use of information is, which requires increasing the relationship of information of EMS and DMS. So we can compare the running parameters of many correlative components or systems in some districts according to the relationship of net components from history database, and calculate the datasheet reflecting the running state of power system.The compositive application system based on the minimum information of power net database is brought forward to solve this problem. It is independent with original information database, and completes three functions through analyzing and calculating: (1) Analyzing the network topology relationship between components and stations according to the connection and running state of components of power network. So we can combine the data of EMS with data of DMS in a certain extent, and set up the foundation of minimum information extraction and datasheet construction. (2) Extracting the minimum information state. The minimum information state indicates the information state reflects the security,reliability and economy of power supply system. The minimum information of components includes geometry information, physical parameter, real time information and reliability information. (3) Constructing the datasheet system. These datasheet systems include the voltage report forms, power report forms, network loss report forms and reliability report forms.From above we know, the mainly merit of the compositive application system based on the minimum information of power net database consists in that it can combine the conelative data of EMS with DMS based on their logistic connection through network topology and data mining. It can analyze running data of power...
