Offshore wind turbine environment parameter test device

Abstract

The present invention provides an offshore wind turbine environment parameter test device. The device comprises a wind test system, a wave test system, a flow test system and a main control system. The wind test system employs a laser radar wind meter to measure wind parameters of multiple points and send the wind parameters to the main control system; the wave test system is configured to measureparameters of waves and send the parameters of waves to the main control system; the flow test system is configured to measure water flow parameters in a range from a seabed to a water surface heightand send the water flow parameters to the main control system; and the main control system is configured to receive and process data measured by the wave test system and the flow test system. The technical scheme provided by the invention has many test physical quantities such as wind speed, a wind direction, flow rate, a flow direction, a wave height and a wave direction, many measurement work conditions, long test time, and high in precision and can provide accurate environment parameter input condition for following load simulation calculation, and each sub system and the main system are subjected to serial communication to allow the signals not to be easily interfered.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to an environmental parameter testing device for an offshore wind turbine. Background technique [0002] At present, China's offshore wind power has entered the stage of large-scale development, and has moved from the intertidal zone to the offshore and far seas, and the characteristics of wind resources are more diversified. The power and size of wind turbines are becoming larger, and at the same time, they need to deal with more extreme and severe weather and sea conditions. This requires wind turbines to have accurate environmental data during certification and testing, which is directly related to the quality of certification and testing and the safety of subsequent wind turbines. [0003] IEC (International Electrotechnical Commission) has promulgated the latest international standards for wind turbine testing (IEC61400-12-1:2017 and IEC 61400-13:2015). The new version o...
