DWC Wind Turbine Load Test System Scheme

DWICH wind turbine load test system can be applied to verify the design load of wind turbine, optimize the design scheme of wind turbine, detect the quality of wind turbine, and curb the occurrence of safety accidents. It has strong practicability and flexibility. The load test system of DWC wind turbine is a distributed test system, which mainly consists of the following parts:

• Tower bottom main acquisition system

• Hub sub acquisition unit

• Cabin sub acquisition unit

• Anemometer sub acquisition unit

At the bottom of the tower is the main data acquisition system of DVC. It communicates with the sub data acquisition units distributed in other parts of the fan by means of CAN bus. The functions of the main acquisition system include system initialization, operation monitoring, real-time storage of collected data, test data processing and other functions.

The configuration of the main acquisition and sub acquisition units of DVC is as follows:

• 2 strain sensor signal channels

• 1 active power transmitter signal channel

• 1 reactive power transmitter signal channel

• 4 spare signal input channels for unit operation parameters or strain measurement parameters

• 8 digital signal input channels of wind turbine operating parameters

• 4 wind turbine operation parameter coding signal input channels.

• 3 strain sensor signal channels

• 1 yaw position sensor signal channel

• 2 acceleration sensor signal channels

• 10 reserved input channels for wind turbine parameters or other strain sensor signals

3. Hub sub acquisition unit (including 16 analog signal channels)
