Brief description of the drawings
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of hybrid power system using at three-phase alternating current source, comprise the first filter 1, rectification feedback device 2, two-way inverter 3, battery pack 4, the second filter 5 and transformer 6, described the first filter 1 is electrically connected with rectification feedback device 2, described battery pack 4 is electrically connected with rectification feedback device 2, described two-way inverter 3 is electrically connected with rectification feedback device 2, described the second filter 5 is electrically connected with two-way inverter 3, described transformer 6 is electrically connected with the second filter 5, described rectification feedback device 2 is made up of the series-parallel switching tube group of at least three groups, and every two of switching tube in every group of series-parallel switching tube group is to be relatively oppositely electrically connected, described two-way inverter 3 is made up of at least two group switching tube groups, described battery pack 4 is via in reactor access rectification feedback device 2.
As shown in Figure 1, between generating set or external power source 7 and crane power consumption equipment 8, add the technical scheme of hybrid power system of the present utility model.Battery pack 4 is connected between rectification feedback device 2 and two-way inverter 3, the three-phase alternating current of generating set or external power source 7 becomes direct current after rectification feedback device 2, now battery pack 4 is connected on this direct current, common release or storage power, two-way inverter 3 effects are to crane work equipment and auxiliary equipment power supply, in the time that crane has excess energy, can be oppositely by the energy of crane to battery storage.Arrow represents the flow direction of energy under different conditions.Battery pack 4 parts are also furnished with independent battery manager, on figure, do not represent.
Energy flow (1): in the time that crane needs energy, be mainly crane while slinging weight, generating set or external power source 7 provide electric energy to crane jointly with battery pack 4.
Energy flow (2): in the time of crane feedback energy, be mainly crane while transferring weight, crane charges to battery pack 4, if what use is not generating set 7, can also be by rectification feedback device 2 by energy feedback to electrical network.Therefore this rectification feedback device 2 is the controlled self adaptation rectification feedback device of special research and development.
Energy flow (3): in the time that the energy content of battery is not enough, can charge to separately battery pack 4 by generating set or external power source 7.
Energy flow (4): this device also can be realized battery pack 4 outside is released energy, but on crane, this energy flow does not use.
Energy flow (5): when enough or self-shield, the energy of crane feedback will consume through energy consumption equipment 9 on resistance 10, prevent that noenergy from flowing back to road and causing equipment damage in the energy content of battery.
