Abstract

The invention provides a full-power converter for a wind turbine generator set. The full-power converter comprises an engine room converter system, a direct-current energy transmission unit and a tower bottom converter system, wherein the engine room converter system is located on an engine room platform of the wind turbine generator set and is configured to a structure for converting low-frequency alternating current energy generated by the wind turbine generator set into direct current energy; the direct-current energy transmission unit is located in a tower barrel of the wind turbine generator set and is configured to a structure for transmitting the direct current energy to the tower bottom converter system from the engine room converter system; the tower bottom converter system is located on a tower bottom platform of the wind turbine generator set and is configured to a structure for converting the direct current energy into work-frequency alternating current energy meeting power grid requirements.

Description

technical field [0001] The invention relates to the field of wind power generation, and more particularly relates to a full power converter for a wind power generating set. Background technique [0002] With the intensification of the energy crisis, the development and utilization of new energy has become a research hotspot. A wind turbine is a power device that converts wind energy into mechanical energy, which drives the rotor of the generator to rotate, and finally outputs alternating current. Due to the unstable air volume of the wind turbine, the voltage of the low-frequency AC output is also unstable. Usually, the low-frequency AC energy output by the wind turbine is converted into DC power through rectification, and then the DC power is converted into AC mains power through an inverter circuit. , to ensure stable use. [0003] The current wind turbines use centralized layout and integrated full power converters for energy transmission and conversion. The converter ...
