New Information Shared Power Automation System

An advanced distributed electric automation system was proposed, whose information will be shared in enterprise level. The new system includes management level and substation controller level. Substation controller plays a very important role in the system. Sampling, dealing, storing data from the device and exchanging data with other substation controller or upper level system are its main task. Management level is divided into substation controller and special management center such as dispatch center. Management software can be installed in management center or in substation controller. All the substation controller and management center are connected by wide area network, while in the substation controller communication is based on local area network.
