Stream harmonic wave is the main cause causing voltage harmonic and power equipment to damage.Therefore, seek effectively to suppress the side of current harmonics
The focus of method research the most at present.
The method of suppression current harmonics mainly has two classes: one is actively to administer, by transforming power electronic equipment
Make it not produce harmonic wave, and power factor controlling is 1, typical such as power factor correcting.Two is passive improvement, installs humorous
Ripple compensation device carrys out compensation harmonic, typically has passive filtration unit and active filter.Traditional method is with passive
LC wave filter, simple in construction, can compensate for harmonic wave, it is possible to compensating reactive power, the scope of application is very wide, and shortcoming is to rely on electrical network and load
Parameter, compensation characteristic is easily affected by electric network impedance and running status, easily and system generation parallel resonance, makes wave filter mistake
Carrying and even burn, the weight of device is big simultaneously, and volume is the biggest.Active Power Filter-APF has perhaps compared with traditional passive filter
Many advantages: the harmonic wave that frequency and amplitude change can be carried out dynamic compensation；Harmonic wave can be optionally compensated for；Simultaneously by electrical network
The change impact of impedance and load is less, and resonance will not occur；Increase compensation capacity is convenient.It is based on these characteristics, has
The application of active power filter is more and more extensive.But what the active filter of existing market used is all the control of wired touch screen
Technology, in the device debugging stage, in order to ensure the safe operation of device, need to have people on the scene on duty, considerably increase manpower financial capacity；When
When it puts into scene operation, it is impossible to understand operation conditions in real time, remotely monitor.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, it is achieved remotely monitor active filter, the present invention provides the one can
The active filter of radio communication.
Technical scheme: a kind of can the active filter of radio communication, including soft-start module, filtration module, power mould
Block, energy-storage units, driving module, control module and wireless communication module, in circuit, being used for will for the series connection of described soft-start module
Starting current controls in safety range；The filtered module filtered of three-phase electricity is followed by power model；Described energy-storage units is connected in parallel on
On power model；Described control module is for Real-time Collection, process data and sends signal, described driving module to driving module
For driving power model；Described wireless communication module is connected with control module, for the wireless telecommunications of signal.
Beneficial effect: the present invention provide a kind of can the active filter of radio communication, be configured with wireless data transmission
Module, can carry out data interaction with wireless terminal, and this device controls flexible, easy to operate.When active filter puts into fortune
After row, user can be connected with the wireless communication module foundation of device by user terminal, is filled to active power filtering by user terminal
Putting and send control instruction, active filter performs corresponding order according to the control instruction that user terminal sends.User simultaneously
Can also be by the running status of user terminal long-distance monitorng device and relevant data message.Just can be complete without mobile subscriber
Become all working, also provide the user a comfortable noiseless working environment.The present invention has and reduces body, saves into
Originally, the features such as freedom, long-range monitoring are operated.
