Background technology
Frequency converter is important component essential in wind power generating set.Frequency converter passes through to double-fed asynchronous wind-power electricity generation
The rotor of machine carries out excitation so that and the amplitude of the stator side output voltage of double-fed generator, frequency and phase are identical with power network, and
And active and idle independent uneoupled control can be carried out as needed.Frequency Converter Control dual-feed asynchronous wind power generator realize it is soft simultaneously
Net, reduce grid-connected dash current and adversely affected to caused by motor and power network.
Existing frequency converter is made up of main circuit system, distribution system and control system.Including stator it is grid-connected switch, it is whole
It is flow module, inversion module, input/output wave filter, IGBT, PLC, JCE1000-AXS current sensor, blower fan, active
The parts such as Crowbar circuits, controller, monitoring interface.Main circuit of converter system includes rotor side inverter, dc bus list
Member, power network side rectifier.Distribution system is made up of grid-connected contactor, main circuit breaker, relay, transformer etc., and itself is integrated with
Grid-connection control system, user need not be reconfigured at grid-connection cabinet, improve level of integrated system, saved cabin space, can also have been carried in cabinet
For the 220V power supplys of field adjustable.Control system is by high speed digital signal processor (DSP), man machine operation interface and programmable patrols
Controller (PLC) is collected to collectively form.Whole control system is equipped with uninterrupted power source (UPS), is easy to system during Voltage Drop to have
Uninterrupted operation ability.
Above-mentioned each function distribution is into switch board, power cabinet, grid-connection cabinet.
Switch board：Switch board is mainly analyzed the various analog and digital signals gathered back, sends control instruction, control
The running status of current transformer.Switch board is mainly made up of Main Control Tank, PLC, wave filter, power module etc..
Power cabinet：The transmission of main responsible rotor slip energy.Power cabinet mainly by power model, IGBT, PLC,
JCE1005-FS current sensors, blower fan, active C rowbar etc. are formed.
Grid-connection cabinet：Be mainly used in current transformer be connected with generator system and power network control, the collection of number control signal with
And the configuration of secondary circuit.Grid-connection cabinet is mainly by breaker, contactor, signal collecting element, UPS, heater, signaling interface portion
Grade composition.
Wind-power electricity generation frequency conversion device power cabinet is closing at work, therefore installation power cabinet door plate is needed before work,
And door-plate surrounding and power cabinet are fixed.At present, the installation of power cabinet door-plate is lifted door-plate simultaneously by multiple staff
It is corresponding with the screw mounting hole on power cabinet, then there is special people to carry out screw and fix.Because power cabinet door-plate size is larger, tool
There is certain weight, and it is higher to the status requirement of mounting hole, need manpower relatively more when lifting door-plate, and waste time and energy,
The installation inconvenience of power cabinet door-plate.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of simple in construction, power cabinet door can be realized
The Fast Installation of plate, and installation is laborsaving convenient, saves the wind-power electricity generation frequency conversion device power cabinet door-plate Fast Installation knot of human resources
Structure.
