Description

technical field [0001] The invention relates to a hardware-in-the-loop experiment system and method for testing a main control system of a wind power generator. Background technique [0002] With the increasing complexity of the wind turbine control system, higher requirements are put forward for the real-time performance and flexibility of the simulation system. At present, the test of the main control system mainly adopts the following route: off-line algorithm simulation platform --> full power drag platform --> on-site wind turbine test. The disadvantage is that there is distortion and disconnection between offline simulation and actual operating conditions, and the limitation of real-time performance leads to low confidence of simulation results. At the same time, the offline simulation platform is not suitable for failure mode analysis. [0003] Although the full-power dragging platform can test the operability of the electrical system for various components su...

Problems solved by technology

The disadvantage is that there is distortion and disconnection between the offline simulation and the actual operating conditions, and the limitation in real-time performance leads to low confidence in the simulation results

At the same time, the offline simulation platform is not suitable for failure mode analysis

[0003] Although the full-power dragging platform can test the operability of the electrical system for various components such as gearboxes, generators, and converters, the dragging platform lacks testing for software and core algorithm performance, and the testing process for extreme conditions exists. Risk, may cause damage to large electrical components, while occupying a large area and high cost

[0004] The disadvantage of the real wind field is: due to the uncertainty of the weather conditions, the test of the functions of the main control will result in high wind field test costs, a lot of time and human resource consumption (for example, the test of extreme wind conditions may need to wait for one month. above time), the risk of accidents is also higher

Therefore, it is a huge challenge for the hardware-in-the-loop experimental platform to reflect the real response of the wind turbine as much as possible while ensuring real-time performance (for example, the minimum response time of the main controller of the wind turbine is 10ms).
