Introduction of SCADA system
 

The SCADA (Supervisory Control and Data Acquisition) system is computer-based, wind farm operating control system. The operator of wind farms can monitor and control the wind turbine by data acquisition, data storage, equipment Control, parameter measurement, data adjustment, fault alarm, automatic generation of operation reports etc. SCADA system can guarantee the completeness of wind turbine information, provide the information of the status of the turbine ,conduct rapid diagnostic of equipment failure and increase production efficiency, so the whole wind farm can be operated in a safe, reliable and economical way.
 

The SCADA system wind farm monitoring solution is shown as below.
 

Remote Monitoring
 

 
Wind farm remote monitoring system can collect and supervise the wind farm real-time operation information , so the operator will get the wind farm information without going to the site, and the abnormal and alarm signal will be realized timely, so the safety and reliability of the wind farm will be guaranteed. This system can also compare and analyze the operation data of different wind farm so the decision making process will be supported by this information and the enterprise profit will be increased.
 

Vibration monitoring
 

Wind turbine is the most important equipment in wind farm. In order to guarantee the safety operation of the turbine, vibration monitoring of the key parts is very critical. Real-time wind turbine vibration monitoring system uses vibration sensors fixed on the main shaft, generators, gear box and other locations to collect signals received by the sensor, and these vibration information will be upload to the host computer for analysis and display by data acquisition system, so the safety operation of wind turbine is guaranteed.
 

Diagnosis Expert System
 

Diagnosis expert system will not be influenced by the time, location or environment, it can diagnose the wind turbine operation condition correctly and completely, so the operating efficiency of the wind turbine will be increased, the downtime of the wind turbine will reduced and the profit of the wind farm will be increased. At present the diagnosis expert system composed of basic information acquisition, knowledge database, information storage database, knowledge database management etc.
 

Audio & Video monitoring system
 

the operating information of the wind turbine can be supplemented by the video monitor system, the operator can adjust the angle and focus of the video camera freely, so he can hear the abnormal sound of the gearbox, generator yaw system and blade in the control room, so the potential failure can be found .The voice conversation can also be made among the wind turbine, wind farm control room and company headquarter office by IP voice gateway.

Wind farm power management platform

Wind farm power management platform can provide the high quality electric power by adjustment of the active and reactive power generation .the power generation can be limited by intelligent and fast adjustment without shutdown of the wind turbine. The output voltage of the wind farm can be adjusted by reactive power adjustment.
