Product Center >> Power Automation Systems >> Power Dispatching Automation System

Brief introduction
Dispatch system is developed with new thought, new technology and new strategy based on the comprehensive analysis of the defects and limitations in domestic traditional SCADA system. The system applies to the county electric power dispatch system, railway water and electric dispatch system etc, can also be used in other fields such as telecommunications, transportations, petrol, chemical industry, environmental protection and water conservancy etc with a wide applicability.
The system adopts various latest technologies of computer fields, such as the technology of object – “Object Oriented Programming” and Opening Data Base Connectivity etc., fully distributed architecture, and it can implement the functions of plug-in application program expansion, external data base access and calling other commercial software as system tool software, which makes the system to have a great extended compatibility with a strong professional characteristic.
Typical application
These drawings are only as a reference for the system structure, the detailed dispatch automatic system is determined by the scale and function requirement.
