Technical Field
The utility model relates to the technical field of complete machine noise test of wind turbine generators, in particular to a portable signal tower for a complete machine noise test system of a wind turbine generator.
Background
In recent years, the noise problem of wind turbines is more and more prominent, and the emphasis on the noise problem is also increased. The reliable noise test can reflect the noise propagation characteristics of the wind turbine generator, standardizes the noise level of the wind turbine generator, and provides reliable theoretical basis and data support for noise design and noise reduction work of the wind turbine generator.
In the conventional IEC 61400-11-based wind turbine generator complete machine noise test, an acoustic signal station, a wind measuring tower signal station, a main control signal station and an acquisition base station are located at 4 different positions, and the mutual distance is 100-300 meters. The signal transmission can only adopt a wireless transmission mode.
Acoustic signals, anemometer tower signals and master control signals need to be in good signal communication with the acquisition base station. At present, the installation mode of the signal base station is fixed by a higher equipment mechanism (such as a cooling fan) through a binding belt and a rope, and the material taking, the installation and the disassembly are very inconvenient. When the wind condition is large, vibration of the acquisition base station is caused, and communication disconnection or signal instability can be caused by self vibration and heat dissipation of the equipment mechanism.
In order to enable the signal communication of the complete machine noise test system of the wind turbine generator set to be stable and the data acquisition to be efficient and accurate, a portable signal tower is urgently needed.
