Problems solved by technology

However, the electrical part of the fan cannot realize the transmission of the high-precision permanent magnet synchronous PMSM model and the FPGA electronic circuit hardware solver netlist model to the chip of the FPGA simulation lower computer, so as to realize the real-time simulation of the motor with nanosecond step size and the three-level topology. solve

[0007] Combining the existing simulation technology solutions, it can be seen that there is still a lack of comprehensive real-time simulation platform for large-scale wind turbines, and the hardware-in-the-loop real-time simulation of the comprehensive control system for the mechanical, pneumatic, and electrical systems of wind turbines has not been fully realized. In particular, there is no simulation platform with technical characteristics such as nanosecond-level refined simulation model and high-precision nonlinear motor body model for the electrical part of the fan
