Application of Data Mining Theory in Power Grid Equipment Defect

n order to meet the structural and functional demands of power grid planning research simulation laboratory for application data processing, a set of application data subsystem serving the power grid planning research simulation laboratory is designed according to the actual demand of power grid planning simulation work. Not only the overall framework but also the specific functions are described in this article in order to present the design thought for the data subsystem serving the power grid planning research simulation laboratory, wherein the data bus based integration method is adopted for the application data subsystem, and CORBA is adopted to solve the problem regarding the interoperability of the distributed objects of different heterogeneous systems, and open structure is adopted to provide the network architecture with key function redundancy and able to support distributed processing environment in order to meet the demands for expandability, safe reliability, openness and easy maintenance. Specifically, the main functions realized thereby include: data exchange platform, data center, graphic center, data query, information service, WEB, uniform information maintenance platform, uniform platform support for accessed/ embedded third-party application functions and other basic functions, and these functions aim at improving power grid planning simulation level and verifying more reasonable planning scheme in order to create greater benefits.
