ABSTRACT
There are more and more production and management data collected and produced in power information systems, their procession and calculation play an important role in the operation and decision of power companies[1-2]. As data structure in the information system is dierent from each other, it always needs to develop specific g function module to realize data procession which is dicult to extend or reuse [3], the solution is to design a configurable tool to do the data procession and make sure it isn’t limited to the data structure[4].
