In view of the disadvantages of PSD-BPA software in text interaction between provincial and regional dispatching

such as large amount of data transmission

lack of checking mechanism

difficulty in authority management

complexity in parameter conversion

this paper proposes a management strategy for the integrated provincial and regional equipment parameters of power systems. According to an analysis of data which will be stored in a database

a complete parameter checking mechanism based on the flyweight pattern

pre-defined and self-defined formulas

typical parameters

and actual measured parameters is developed. Furthermore

depending on detailed recorded logs

strictly controlled verification and approval process

conversion between various types of parameters throughout modeling

and assigning management authority according to dispatching institutions

a unified management platform is developed for achieving refined and intelligent management of integrated provincial and regional equipment parameters．Actual application in Yunnan power grid and its 17 regional dispatching departments shows that the proposed method and platform are practical while able to greatly improve work efficiency.
