However, at present, this property is rarely considered in the design of key components of wind turbines. The harmonics in the air gap of the generator are large and the temperature rises. In addition, the stator lead wires of the wind turbine generator are densely distributed on the stator side, which increases the welding and insulation of the lead wires. Craft Difficulty

Abstract

The stator winding connection line structure is used for a generator stator, the generator stator comprises a stator iron core, a stator punching sheet of the stator iron core comprises a plurality of tooth poles, stator grooves are formed among the tooth poles, stator coils are arranged on the stator grooves, one end of each stator coil is provided with a stator coil outgoing line, and the other end of each stator coil outgoing line is provided with a stator winding. And the stator coil outgoing line is connected with the conducting ring. According to the stator winding connection line structure of the wind driven generator, the influence of a stator tooth part on air gap flux density is reduced through the arrangement of semi-open slots, the temperature rise of a motor is effectively reduced, the service life of the motor is prolonged, and when one set of stator winding breaks down, the other set of winding reduces power and can still generate power to a power grid through the arrangement of two sets of windings. And the stability of double-winding grid-connected power generation is highlighted.

Description

technical field [0001] The invention belongs to the technical field of wind power generators, and relates to a stator winding wiring structure of a wind power generator. Background technique [0002] According to the requirements of grid-connected guidelines for new energy grid-connected power generation systems, wind turbines must meet the requirements of power quality before they can be connected to the grid for power generation. In order to meet this requirement, some control strategies are used to suppress power harmonics before wind turbines are connected to the grid, which plays a significant role in optimizing power quality. However, at present, this property is rarely considered in the design of key components of wind turbines. The harmonics in the air gap of the generator are large and the temperature rises. In addition, the stator lead wires of the wind turbine generator are densely distributed on the stator side, which increases the welding and insulation of the l...
