The invention is a design based on an intelligent design platform application system, belonging to the field of the application of the calculation analysis module of a power grid decision. The system adopts the hardware environment of a regional power grid dispatching decision support system, support platform software and data platform software, wherein the hardware part can be divided into computer network, data acquisition, real-time monitoring and control, historical data storage, network safety equipment, dispatcher workstation, maintenance workstation and the like, and the software of the system adopts a WINDOWS system, a database system Oracle, an advanced support platform and application software. Real-time data collected by a computer network and a data acquisition module is sent to a real-time monitoring and controlling module by being communicated with a communication server and is variedly processed and transformed; relevant parameters are stored in a historical data storage module; finally, a machine operating the advanced application software of an operation power grid serves as a terminal workstation which also doubles as a client; and a man-machine conversation window provides a handling means for operation personnel and dispatchers.
