Description
Technical field
The present invention relates to locomotive crane tool power set, particularly the net electricity is powered, and utilizes the locomotive crane tool power set of accumulator reclaiming energy.
Background technology
The locomotive crane tool is port and pier forward position and part building hoisting machinery commonly used, and it utilizes the net electricity, moves in orbit by road wheel.The locomotive crane tool is compared with the rubber tired crane tool, has with the net electricity to drive, and is pollution-free, can add big elevating capacity and lifting velocity, but advantages such as the quick walking of cart hoisting.
Its operating feature is periodic batch operation, and the frequent goods with several tons to tens of tons rises and descends, starts and braking.And operation Once you begin, just require continuously to carry out, and reach desirable loading and unloading, handling efficiency.In short several seconds, finish starting and braking, need very big power.Under so huge load variations, require to rise in short-term braking, bring some disadvantages for the locomotive crane of net electricity power supply:
1. the regenerated energy of locomotive crane tool is not rationally utilized.Before Application of frequency conversion technique, the decline potential energy of locomotive crane tool and other mechanisms can only make it satisfy the requirement of the urgent wind prevention braking of gradual braking under the various operating modes and high speed shaft by the dynamic braking mode because of the regenerated energy of braking feedback.Resistance heating consumes regenerated energy, promptly wastes energy and increases the thermal pollution of complete machine.
2. impact is very big, and the operation of locomotive crane tool complete machine is steady inadequately.Because powerful Fraquent start in short-term impacts very big to unit load.After the AC frequency conversion control technology was implemented, the locomotive crane tool of major part net electricity power supply to electrical network, brings very big impact to whole electrical network with Way of Regenerating Energy Feedback, and was also very big to the electric power system impact of complete machine, causes electric equipment to damage easily.
Chinese patent " hybrid electric tire gate-type is hung the ship machine " (patent No. is ZL200410012876.4) constitutes hybrid power system by generator and batteries, use the performance of improving power set to reduce its exhaust emission by the coordination of generator and batteries, but do not reclaim the regenerated energy that hangs a large amount of feedback potential energy formation that exist in the ship machine course of work, regenerated energy is not still rationally utilized.
Super capacitor is a kind of novel energy-storing element, thermal energy storage process is reversible, the capacitance of electrochemical capacitor can be up to farad level even farad up to ten thousand, can realize that rapid large-current discharges and recharges, and have higher power density than storage battery and (can reach 1, the 000W/kg order of magnitude) and longer recycle the life-span (discharging and recharging number of times can reach 100,000 times), can in exceedingly odious environment such as utmost point low temperature, use simultaneously, and non-environmental-pollution.
Chinese patent " utilizes the super capacitor tire type gantry container crane ", and (patent No. is 02151021.0) is connected into super capacitor in the tire type gantry container crane dynamical system of diesel-electric set electric supply, utilize the regenerated energy of the fast charging and discharging characteristic recovery operation mechanism action formation of super capacitor, this dynamical system has reduced toxic emission to a certain extent, but diesel engine noise was big when still there was startup in it, fuel combustion is incomplete, and the deficiency of discharging black smoke, aspect environmental protection, need to improve greatly.
Summary of the invention
The object of the present invention is to provide a kind of pollution of the configuration minimizing of locomotive crane tool power set of passing through to improve, utilize the locomotive crane tool novel power device that utilizes accumulator that reaches energy-conservation by accumulator reclaiming energy again environment.
To achieve these goals, technical scheme of the present invention is: comprise net electric installation, rectifying device, accumulator, inverter, energy consumption resistance, electric capacity of voltage regulation and work drive motor.The net electrical propulsion unit is connected to rectifying device, and rectifying device connects energy consumption resistance by dc bus, and energy consumption resistance connects inverter again, and inverter connects work drive motor, will convert the controlled alternating current of frequency from the direct current of dc bus to and supply with work drive motor.Be connected with electric capacity of voltage regulation on dc bus, the two ends of electric capacity of voltage regulation connect the positive and negative level of dc bus respectively.Accumulator connects two-way DC/DC converter, and two-way DC/DC converter is parallel to dc bus electric capacity of voltage regulation place again.
Two-way DC/DC converter is made of the parallel connection of two individual event DC/DC converters, realizes the energy two-way flow.
Accumulator can select for use super capacitor separately as accumulator, also can the combining super capacitor fast charging and discharging, the characteristics of high-power characteristic and the big specific energy of storage battery, constitute by the super capacitor multiple-connected battery.
NetTone Communicator over commutation device becomes direct current, again by the inverter conversion, converts direct current the AC power AC of frequency and voltage controlled to, is used to drive work drive motor.
Be connected in parallel on the DC power bus after accumulator connected two-way DC/DC converter, utilize DC power bus monitoring voltage excursion, when direct voltage rises owing to operating mechanism's motor regeneration feedback electric energy causes, accumulator enters charged state, along with accumulator constantly charges, its terminal voltage rises, and DC power bus voltage and then rises, and accumulator has absorbed the regenerated energy of all mechanism's feedbacks.
Need energy supply when action when operating mechanism is in, operating mechanism's machine operation causes dc bus voltage to descend, the accumulator discharge, and along with accumulator constantly discharges, its terminal voltage descends, and DC power bus voltage descends thereupon.
The utility model has following advantage owing to adopted accumulator reclaiming energy:
1. the regenerated energy of utilization accumulator recovery all working mechanism feedback is saved energy as work institute energy requirement, effectively improves the stationarity of locomotive crane tool power set.
2. reduce the complete machine capacity;
3. the recycling of regenerated energy has reduced because the feedback of recuperated energy to the impact of electrical network and electric power system, has reduced the thermal pollution that environment is caused simultaneously.
