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.
High power density: power density is increased by 30%, which improves the
flexibility of unit design
Platform design: the size and structural layout of the entire series of converters
are kept consistent, reducing unit design work
Spare parts normalization: the key components of the full range of converters
such as grid-connected contactors, fans, etc. are designed to be unified, reducing
the types of spare parts
Optimized heat dissipation design: Optimize the heat dissipation layout in the
cabinet, and add external cooling fans to improve the environmental adaptability of
the converter
Improve converter efficiency: optimize filter design, reduce grid side and rotor
excitation current, and reduce converter loss
Remote monitoring and intelligent diagnosis: realize the intelligent diagnosis of
fan faults through the remote networking system of the converter
