Problems solved by technology

However, since the direct-drive generator works at a low speed of tens of revolutions per minute, in order to ensure its output voltage and frequency are within the normal range, the generator needs to adopt a larger diameter of the stator and rotor and a larger number of pole pairs. Large and heavy, which adds great difficulty to the design, manufacture, transportation and installation of the generator

Embodiment Construction

[0037] The invention provides an electric excitation magnetic flux switching generator. The system mainly includes a wind turbine, an electric excitation magnetic flux switching generator and a controller; the wind turbine is connected to the electric excitation magnetic flux switching generator, and the electric excitation magnetic flux switching generator On the one hand, it is connected to the controller, and on the other hand, it is connected to the step-up transformer through an uncontrollable rectifier bridge and a three-phase inverter. The three-phase inverter outputs a feedback signal to the controller; the controller then controls the electric excitation flux through the excitation Switch the generator.

[0038] The two ends of the open winding of the field winding of the generator are directly powered by two multilevel inverters. Two sets of windings are embedded on the stator, namely the armature winding and the field winding. The field winding end is designed as an ope...

Abstract

The invention provides a wind power generation-used modular electro-magnetic flux switching power generator. The inner part of the wind power generation-used modular electro-magnetic flux switching power generator is composed of a shell, a stator assembly and a rotor assembly. Two sets of windings, that is, an armature winding and an excitation winding, are embedded and placed on the stator assembly; the excitation winding is located at the outer side of the armature winding; the excitation winding is connected with a controller and is connected with a power grid via the controller and a transformer to serve as AC excitation; an electro-magnetic flux switching wind power generator is on one hand connected with the controller and is on the other hand is connected with a boosting transformer via an uncontrolled rectifier and a three-phase inverter to be connected into a power frequency power grid to serve as electric energy output, and the three-phase inverter outputs inversion control signals to the controller; the controller controls the electro-magnetic flux switching wind power generator via excitation current, the stator module is composed of an excitation winding and an armature winding, the excitation winding embedded inside soft iron is arranged above the armature winding, the position of the excitation winding is movable, and an excitation field is changed through controlling the magnitude of the current inside the excitation winding.

Description

Technical field [0001] The invention relates to a wind power generation equipment, in particular to an improvement of the internal structure of a generator. Background technique [0002] As the whole society continues to pay attention to energy and environmental issues, the development and utilization of renewable energy is showing a trend of accelerated development. Wind energy, as one of the most mature renewable energy sources in the development and application of technologies currently mastered by mankind, plays an important role in sustainable social and economic development by virtue of its large exploitable quantity, wide distribution area, safety and environmental protection and other advantages. According to data released by the Renewable Energy Professional Committee of the China Resources Comprehensive Utilization Association, China's total installed capacity of 41800MW has been put into operation in 2011, surpassing the United States to become the country with the lar...
