Charging station with regard to present domestic construction; The utilization of electric automobile charging station coordination charge control method does not make the voltage waveform distortion of points of common connection; Safety, high-quality, economical operation to electric power system constitute potential threat, and electric circumstance brings great pollution around giving.Specifically; Harmonic wave will make production, transmission and the utilization ratio of electric energy reduce; Make the electric equipment overload, generate heat even burn, cause local parallel resonance of electric power system or series resonance, cause relaying protection and automatics misoperation; Make electric energy metrical error etc. occur, seriously disturb and endanger the performance and the operate as normal of electronic equipment and protection control appliance.
Generally regulate charge power with the pulsewidth of regulating IGBT after the fixed-frequency of IGBT or with the frequency of the secured adjusted IGBT of the pulsewidth of IBGT, this way effectively harmonic wave of filtering generation can't be carried out dynamic adjustments according to mains frequency more.This electric automobile charging station is under the prerequisite of as far as possible meeting customer need, and the coupling system load condition is avoided peak of power consumption; Avoid circuit, transformer overload is realized the configuration of electric power resource economical and effective; And the harm that can avoid harmonic wave that electrical network is brought effectively, the stability of increase electrical network.
The utility model content
The purpose of the utility model provides a kind of electric automobile charging station that can administer according to demand and network load adjustment charge power harmonic.
For reaching above-mentioned purpose; The utility model provides a kind of electric automobile charging station; Comprise detecting unit, the control unit of electrical network, detection of grid parameter, the charhing unit and the external-connected port of connection electrical network; Detecting unit, control unit and charhing unit are linked in sequence through the CAN bus, it is characterized in that: external-connected port connects control unit; The dynamic adjusting device of mains by harmonics also is set, the dynamic adjusting device of control unit control mains by harmonics in the charhing unit.
External-connected port connects control unit, can send and control the dynamic adjusting device of mains by harmonics again after teleinstruction is given control unit.
As preferably, the dynamic adjusting device of said mains by harmonics is the IGBT inverter.Frequency and the pulsewidth that the IGBT inverter is regulated IBGT according to the grid power of detection makes and guaranteeing that charge power reduces the generation of harmonic wave in maximum; Thereby harmonic carcellation effectively; Increase the stability of network operation; Remove dangerous hidden danger, improve the work quality and the useful life of electrical network and power consumption equipment, increase user of service's fail safe.
Charge power is by the common influence of the frequency of IGBT and pulsewidth, and regulating frequency and pulsewidth simultaneously under the fixing situation of charge power make both reach balance.
The harmonic current of filtering is a triple harmonic current, and triple harmonic current is bigger to the impact of electrical network, is the harmonic current that at first should handle, and the harmonic current of other frequencies is comparatively limited to the influence of electrical network.
Control unit comes the further frequency and the pulsewidth of adjustment IGBT inverter according to the charge power of adjusted charhing unit.
As preferably, said external-connected port is selected from one or both among network interface and the GPRS interface.Do not get rid of other communication interfaces, for example mobile phone remote control.
After the technical scheme that employing the utility model provides, this intelligent charge station can be under the prerequisite of meeting customer need, combined charge station load condition; Avoid peak of power consumption; Avoid circuit, transformer overload is realized the configuration of electric power resource economical and effective; Operating state that also can the Long-distance Control charging station satisfies user's demand; And the harm that can avoid harmonic wave that electrical network is brought effectively, increase the stability of electrical network, further improve the stability of charging station; When filtering harmonic, reduce influence as much as possible, charge efficiency is maximized charge power.
