Measurement system for power curve test and network quality in wind turbines, as well as electrical supply quality.

Measurement system for power curve test and network quality in wind turbines, and power quality. The present invention relates to a measuring system for testing the power curve and network quality in wind turbines, as well as quality of electrical supply in general comprising a measuring device that performs the test power curve and different assays power quality which enables the status of the test being performed at each time, wherein each of the turbines has a measuring device that can indicate the state of the test power curve at any instant of time and distance, plus analyzing the network quality in the wind turbine, which issues reports configurable by a user restricting the transit of data through a communication device to the outside.
