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: 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
