Abstract

The invention relates to a distributed measuring system for the noise of a wind turbine. The system comprises an acoustic measuring end machine, a wind turbine operation parameter measuring node, a wireless communication base station, an acoustic signal processing center, a meteorology and wind turbine data processing center, and a system control, display and interaction center. The acoustic measuring end machine is installed on a noise measuring position, and the wind turbine operation parameter measuring node is installed on a wind turbine; the acoustic measuring end machine and the wind turbine operation parameter measuring node carry out data communication with the wireless communication base station through a wireless mode, acoustic data reaches a first processing center via the wireless communication base station, and the first processing center processes the acoustic data; wind turbine data is transmitted to a second processing center via the wireless communication base station, and the second processing center processes the wind turbine data; and the system control, display and interaction center is used for realize control and data transmission of other modules in the measuring system, interaction with users, and display measuring data and a processing result.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a distributed measurement system for wind turbine noise. Background technique [0002] Wind energy is an important renewable energy source, and wind power generation has become the most mature type of new energy application in my country. [0003] Noise will be generated during the operation of wind turbines. The country has strict regulations on the noise during the operation of wind turbines to avoid its impact on the surrounding environment. Therefore, it is necessary to detect the noise of wind turbines. According to the requirements of "GB / T 22516-2008 / IEC 61400-11:2002 Wind Turbine Noise Measurement Method", the noise test of wind turbines needs to measure the A-weighted sound pressure level and apparent sound level of wind turbines under specified geographical conditions. Power level (integer wind speed, in the range of 6-10 / ms), 1 / 3 octave analysis and other acoustic measu...
