Wind power supervisory control and data acquisition system is an automatic system which used for control and shift of the producing process based on computer. By site supervision and control of running equipments, it can achieve all the functions as data acquisition, equipments control, measure, parameter regulation and various types of signals alarm.

SCADA system aims at establishing a platform for wind power farm supervision data sharing, exchanging and transforming. It can provide remote real-time condition supervision of the distributed terminal, failure diagnosis and maintenance. By diagnosing the failure remotely, maintaining the information supervision and working-state control of every wind farm and machine, transformer substation and anemometer tower all over the country, to bring about industrialization. This system uses the distributed structure of client browser + application server + web server + database server. With layered architecture, the SCADA software design based on 3-layer structure, divides the system into 3 layers as data service layer, business logic layer and data presentation layer.
