Research on hydraulic wind turbine semi-physical simulation platform

摘要

According to a research on the 30 kVA simulation experimental platform of hydraulic wind turbine,its basic structure,composition and operation principle are expounded in this paper.An inverter motor is used to simulate the wind turbine,while a similarity calculation method is applied between the small and large wind turbine.A fixed displacement pump-variable motor closed loop is used as the main transmission system,and a self-excited synchronous generator generates electricity through the grid connection.The experiment and simulation study on the speed and power control of the hydraulic wind turbine is conducted,based on the experimental platform,thus correctness and progressiveness of the experiment platform is further verified.The experimental platform study lays a foundation for further research on the characteristics of hydraulic wind turbine.
