Problems solved by technology
[0003] In the prior art, the meteorological signal acquisition unit for the load test system is mostly designed based on the installation of a wind measuring tower or the use of a ground lidar. No matter which method is used, it involves the problem of temporarily occupying land near the wind turbine, and the installation The wind measuring tower also involves breaking ground, which greatly increases the detection cost and construction period

[0044] A specific embodiment of the present invention is as follows:
[0045] In the wind turbine load test, the main power supply of the load test system is connected to the tower bottom test unit S1 from the 220VAC outlet of the wind tower bottom platform, and then connected to the tower top test unit S2 from the tower bottom test unit, and then connected to the tower top test unit S2 from the tower bottom test unit. One way from the top test unit is connected to the engine room test unit S3, and finally one way is connected to the wheel hub test unit S4 through a slip ring from the engine room test unit to form a series circuit. The main switch is located in the tower bottom test unit. Each test unit contains a 24VDC switching power supply, which converts 220VAC to 24VDC for use by instruments and equipment of different voltage levels. The communication signal of the load test system is formed by the data acquisition instruments in the four test units through the CAN commun...

The invention discloses a wind turbine generator load test system based on integrated measurement engineering and a wind turbine generator, and belong to the field of wind turbine generators. The windturbine generator load test system is used for being mounted on a wind turbine generator to be tested, and comprise a tower bottom test unit, a tower top test unit, a cabin test unit and a hub test unit which are in communication connection, the wind turbine generator load test system further comprises a cabin laser radar connected with the cabin test unit, and the tower bottom test unit furthercomprises a CPU and a storage medium. According to the wind turbine generator load test system, the cabin laser radar is used as a meteorological acquisition sensor, and signal conditioning, real-timeanalysis and network compatibility of standard configuration are provided on the basis of low cost of each channel on the basis of a unified platform, so that restriction of external conditions on measurement engineering is avoided; and dependence on an anemometer tower is eliminated in meteorological data acquisition, the maximum flexibility and economy are provided on the basis of ensuring thestability of the test system, the test cost is saved, and the test period is shortened.
Description
technical field [0001] The invention relates to the field of wind turbines, in particular to a wind turbine load testing system based on integrated measurement engineering and the wind turbine. Background technique [0002] Load testing is one of the key testing items for wind turbines. It is generally carried out when the first newly developed wind turbine goes off the production line. The test results are used to verify the degree of agreement between the finished product and the simulation design. It is a method to evaluate the safety performance of wind turbines. The load test system is a set of detection devices used to implement the load test of wind turbines. According to the requirements of IEC and relevant national standards, load testing needs to collect various types of signal data, including strain signals of key structural components, status signals of wind turbine operation itself, and meteorological signals such as wind speed, wind direction, air pressure, tem...
