Doubly-fed Converter-690V-Liquid Cooling

Hopewind Electric HWDF069 series doubly-fed converters are mainly used in 

wind power systems with doubly-fed generators to obtain the best power 

generation efficiency and power quality. When the generator speed changes 

with wind speed, the converter changes the rotor magnetic field 

by controlling the excitation of the generator rotor, so that the frequency, phase, 

and amplitude of the generator output voltage are consistent with the grid, so as 

to realize the speed change of the wind power system Constant frequency power

generation. By changing the frequency, amplitude and phase of the rotor excitation 

current, the generator frequency, active and reactive power can also be adjusted.

Hopewind Electric provides 690V rated voltage, 50Hz/60Hz rated frequency 1.5MW, 

2.0MW, 2.5MW, 3.2MW, 3.6MW, 4.2MW, 5.6MW and other specifications of wind 

power double-fed converters. The products include many patented technology 

with completely independent intellectual property rights. According to different cooling 

methods, doubly-fed converters can be divided into air-cooled and water-cooled. 

According to different application environments, doubly-fed converters can be divided

into standard type, high prototype, low temperature type, and coastal type.

Performance characteristics

High power density: the maximum single machine power reaches 5.6MW, 

and the power density is increased by 100%

High reliability design: high protection level, especially suitable for high salt 

spray, high pollution and high humidity environments

Flexible layout: building block design, flexible placement, can be extended 

to master/water-cooled integrated machine

The weight of spare parts is small: the weight of a single power module is

11kg, and the maximum weight of wearing parts does not exceed 20kg. 

It is convenient and quick to maintain by one person

Customized cable entry and exit methods: the grid, stator, and rotor exit

positions can be customized to meet different requirements of tower base 

and engine room

Remote monitoring and intelligent diagnosis: realize the intelligent diagnosis

of fan faults through the remote networking system of the converter
