System structure
The KW-2000 intelligent power distribution monitoring system adopts three layers network distributed structure, which includes the station control management layer, network communication layer and field device layer.
1 Management
Station control management for distribution system management, is a direct window of human-computer interaction. Its composition is mainly composed by the system software (including Windows operating system and KW-2000 system) and the server (or workstation), the auxiliary equipment also includes printer, UPS uninterrupted power supply and other related equipment. KW-2000 has a friendly man-machine interface, the collection of all kinds of data information through analysis and processing, and graphics, form, sound and other forms to reflect the operation of the scene.
2 communication layer
The communication control layer is mainly composed of the communication management machine and the bus network. The data layer is a bridge for the exchange of information, for the acquisition of equipment information, classification and storage, and forwarding device layer data to the superior system, and in response to the higher system equipment control instruction.
3 device layer
Device layer is a multi-function instrument, relay protection device for the control of the terminal switch equipment. Through these control systems, can directly control the situation of the field power supply, display, data acquisition.
