Abstract

A system for commissioning a wind turbine is provided. The system includes a test wind turbine, one or more additional wind turbines coupled to the test wind turbine, and a control system. The control system includes a first control module for controlling the one or more additional wind turbines to act as a power source and provide power to the test wind turbine. The control system also includes a second control module for controlling the one or more additional wind turbines to act as a load for dissipating test power generated by the test wind turbine.

First claim

What we claim is:

1. A system for commissioning at least one test wind turbine, the system comprising:
one or more additional wind turbines coupled to the at least one test wind turbine; and
a control system operatively coupled to the at least one test wind turbine and the one or more additional wind turbines, wherein the control system is configured to:
control the one or more additional wind turbines to act as a power source and provide power to the at least one test wind turbine; and
control the one or more additional wind turbines to act as a load for dissipating test power generated by the at least one test wind turbine,

wherein the one or more additional wind turbines provide power to the at least one test wind turbine during a field commissioning acceptance test, wherein the field commissioning acceptance test comprises an energized testing of one or more components of the at least one test wind turbine.

2. The system of claim 1 , wherein a wind turbine of the one or more additional wind turbines comprises an integrated energy storage element.

3. The system of claim 2 , wherein the integrated energy storage element provides power to the at least one test wind turbine.

4. The system of claim 1 , wherein the one or more additional wind turbines act as the load during a validation of a power curve.

5. The system of claim 1 , wherein the control system is configured to control exactly one of the one or more additional wind turbines to act both as the power source and the load.

6. The system of claim 1 , wherein the one or more additional wind turbines comprise a line side power converter, and wherein the line side power converter is configured to supply a voltage to the at least one test wind turbine.

7. The system of claim 1 , wherein the one or more additional wind turbines and the at least one test wind turbine are coupled to a common feeder.

8. A method for commissioning at least one test wind turbine, the method comprising:
coupling the at least one test wind turbine to one or more additional wind turbines;
controlling the one or more additional wind turbines to act as a power source for providing power to the at least one test wind turbine, during an earlier stage of commissioning;
controlling the one or more additional wind turbines to act as a load for dissipating test power generated by the at least one test wind turbine, during a later stage of commissioning; and
performing a field commissioning acceptance test, wherein performing the field commissioning acceptance test comprises performing an energized testing of one or more components of the at least one test wind turbine.

9. The method of claim 8 , further comprising performing a validation of a power curve.

10. The method of claim 9 , wherein controlling the one or more additional wind turbines to act as the power source for providing power comprises controlling the one or more additional wind turbines to act as the power source during the field commissioning acceptance test.

11. The method of claim 8 , wherein controlling the one or more additional wind turbines to act as the power source for providing power comprises controlling an integrated energy storage element in the one or more additional wind turbines to provide power to the at least one test wind turbine.

12. The method of claim 11 , further comprising controlling a line side converter of the one or more additional wind turbines to provide a voltage to the at least one test wind turbine.

13. The method of claim 9 , wherein controlling the one or more additional wind turbines to act as the load comprises controlling the one or more additional wind turbines to act as the load during the validation of the power curve.

14. The method of claim 8 , wherein controlling the one or more additional wind turbines comprises controlling exactly one of the one or more additional wind turbines to act both as the power source and the load.
