Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
The present invention's electricity drives the electric power system of oil special-purpose vehicle and is made up of power supply unit, charhing unit; Power supply unit comprises well site transformer 1, rectifier 2, power model 5 etc.; Well site transformer 1 (90kVA) is connected with rectifier 2 (800A full-wave rectification bridge module), and rectifier 2 is connected with dc bus; Batteries 4 is parallelly connected with dc bus, and batteries 4 is composed in series by 40 12V, 100A.h storage battery; Dc bus is connected with power model 5.The charging system of batteries 4 is, charhing unit 11 is connected with frequency converter 10 respectively, after inversion energy feedback unit 12 connects, is connected with batteries 4 through dc bus, is that batteries 4 is charged.
The present invention's electricity drives the batteries 4 of oil special-purpose vehicle electric power system configuration series connection; Well site transformer 1 is expanded; Its output voltage is identical with DC bus-bar voltage after rectifier 2 rectifications; After 5 inversions of inverter power unit,, realize the operation operating mode of oilfield construction through out put reactor 7 drive motors 8.The special use series connection batteries 4 that disposes in this electric power system, frequency converter 10 dc buss charge through charhing unit 11 through the well site to utilize industrial electrical network.Under the condition that the energy feedback is arranged, like drilling and repairing machine, transfer in the tubing string process, through inversion energy feedback unit 12 mechanical energy that descends is become electric energy, and charge through 11 pairs of batteries 4 of charhing unit; Under the condition that does not have the energy feedback, can adopt the periodic charge mode, guarantee enough supplies of electric power.
It is following to discharge and recharge control principle: the transformer out-put supply is through the frequency converter rectifying and wave-filtering; At the dc bus end; Through filter inductance, battery charging and discharging management Monitoring and Controlling circuit link to each other with batteries (because frequency conversion and inversion meeting generation circulation, the main effect of filter inductance is to prevent that circulation from causing short circuit).System limits its input current; Maximum input current 200A carries out batteries charging after the system start-up, keep it at floating charge state; DC bus-bar voltage is limited in 480V; When the power-supply management system control battery discharging during of the required electric current of load greater than limit value (settings is 180A), with the offset supply undercurrent, and through frequency converter inverter (IGBT power model) through reactor filtering after the supply load motor.All the other time dc buss come the loss of balancing battery group local action with little current, and promptly batteries discharges and recharges with busbar voltage fluctuation and load work done state.
Drive in the circuit of oil special-purpose vehicle electric power system at the present invention's electricity, insert filter inductance 3, electric capacity 9, electric capacity 6, reactor 7 etc., improve the stability of frequency conversion system.
For the transformer that remedies the well site power supply network can not satisfy the deficiency that electricity drives oil special-purpose vehicle electricity consumption needs; The present invention's electricity drives the electric power system of oil special-purpose vehicle and adopts energy to merge mode; Export jointly by batteries 4 and industrial electrical network; Supply with motor 8 and drive the special-purpose constructing device of oil special-purpose vehicle, improve the matching performance of apparatus for work and well head transformer capacity.
