| As the electric grid becoming complicated gradually, with the traditional method to make decision on running mode of district electric grid, workers may bring more mistakes in their daily work and desire to gain the assistant help for their decision through the intelligent software. This paper introduces the ideas of software bus-mastering into the present multilayer power system software architecture of Component-Based Reusage and designs its relevant interface protocol. Thus a integrated and automatic power system software will appear more quickly and it can be sure that the software system studied by this paper could be programmed to be a Advanced Application Component. Aimed at the real substance of workers'work, through intelligent technology imitating the thinking process of workers, this paper gives the theoretic ideas of making decision on running mode by intelligent technology and programming methods, implements its assistant help for professional workers on logic reasoning aspects. What it studies can achieve to make decision on running mode by intelligent technology, reduce the labor amount of workers, guard against their mistakes while they face much more information data to handle and will be very practical. |
