The invention relates to a semi-physical simulation platform of a variable pitch motor of a wind turbine generator, which comprises a real-time simulator, a controller, a load module and an oscilloscope, the real-time simulator is respectively connected with the controller, the load module and the oscilloscope, and an inverter model and a variable pitch motor model are stored in the real-time simulator; a wind turbine generator pitch control algorithm is stored in the controller, a signal of the controller is transmitted to the inverter model, and the controller adopts the wind turbine generator pitch control algorithm to control the inverter model so as to control the pitch motor model; the load module is used for providing load data of the variable pitch motor model for the real-time simulator; and the oscilloscope is used for displaying the data waveform of the real-time simulator. Compared with the prior art, the method is more economical and convenient; non-real-time performance of offline simulation is overcome, time synchronization can be achieved, and real feedback data can be obtained; and the advantages of variable pitch bearing load data under different working conditions and different wind models and the like are considered.

Description

technical field [0001] The invention relates to the field of simulation simulation of pitch motors of wind turbines, in particular to a half-physical simulation platform of pitch motors of wind turbines. Background technique [0002] With the rapid development of wind power generation technology, the capacity and size of wind turbines are getting larger and larger, so there are higher requirements for the design and testing of wind turbines. When testing the pitch algorithm of wind turbines, there are generally the following methods: build a real wind turbine test platform for testing, build an offline simulation model in Matlab / Simulink software for testing, and build a drag motor platform for testing. [0003] When testing the pitch algorithm of wind turbines, if a real wind turbine test platform is used for testing, although the test results obtained are convincing, the cost of building a real wind turbine test platform is relatively expensive, and it is easy to be damage...
