But most of area of China and big city also are faced with the pressing issues of power supply shortage at present, and power supply quality can not be guaranteed especially.Obviously; the reliability of the whole electrical network in the impossible left and right sides of user; but can carry out the electric power protection of self subenvironment energetically; therefore; user's self-protection is the current act that solves the reality of enterprise's electrical problems; and uninterruptible power system (UPS) can solve power outage and power quality problem of unstable effectively, progressively is used widely in every profession and trade.

Existing UPS generally is made up of battery system, when current grid cut-off, is electric by storage battery.Storage battery is the heart of UPS, no matter how advanced the UPS circuit is, its performance finally depends on its battery, in case battery failure, good again UPS also can't provide uninterrupted power supply.The battery system of UPS is made up of lead-acid battery at present, and the battery system volume is big, and the failure rate height need regularly discharge and recharge; Useful life is short, needs periodic replacement (every 3-5), the maintenance cost height; Its performance and reliability can descend in time simultaneously; And power supply is held time and is difficult to above 8 hours; Can't adapt to too high or too low ambient temperature (be lower than 0 or be higher than 20 degrees centigrade).Itself has toxicity lead-acid battery, can produce environmental pollution.

Summary of the invention

At problem set forth above, the utility model purpose is to provide that a kind of reliability height, efficient height, energy density height, charging rate are fast, long working life, ambient temperature required the uninterrupted power supply electric power system of the flywheel energy storage low, that anti-overload ability is strong.

The utility model is realized by following technical measures, a kind of uninterrupted power supply electric power system of flywheel energy storage, comprise UPS, be connected electrically in that UPS goes up and by the load of UPS power supply, it is characterized in that: described UPS also is electrically connected with and switches cabinet and accumulated energy flywheel, this switching cabinet is electrically connected with civil power and diesel generating set, this switching cabinet can be respectively flows to UPS with the power supply of civil power or diesel generating set, carries out two-way electric energy transmitting between accumulated energy flywheel energy and the UPS.

Wherein civil power, diesel generating set, accumulated energy flywheel and switching cabinet all can be connected electrically on the supervisory control system; Supervisory control system can be mounted in the supervising device that switches in cabinet or the UPS.

The preferred magnetically levitated flywheel of above-mentioned accumulated energy flywheel.

The mode that the utility model adopts magnetically levitated flywheel, UPS to combine with diesel generating set provides voltage control and power-failure protecting, and the power supply of good stable is provided, and can protect under critical loads, line voltage decline, fluctuation or power-off condition.Because the utility model has been eliminated the least reliable storage battery part among traditional UPS, the maglev reliability of flywheel is up to 99.9%; Efficient is up to 98% (traditional UPS is up to 93%); Maintenance workload is little, cost is low; Floor space only is 1/4 of storage battery type UPS, the energy density height; Extensibility is strong: single system 120KVA-3.6MVA; Unlimited number of times discharges and recharges, charging rate fast (15 second); Long working life: it is 20 years that product useful life surpasses; Ambient temperature is required low (start-up temperature :-20 ℃ of-40 ℃/operating temperatures: 0 ℃-40 ℃); Anti-overload ability is strong; Pollution-free, environmental protection.This system has high efficiency, high reliability, and characteristics such as high-energy-density and long-time continuous electric power safeguard can solve the problem that traditional UPS exists.

Description of drawings

Fig. 1 is a structured flowchart of the present utility model.

Embodiment

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

A kind of uninterrupted power supply electric power system of flywheel energy storage, comprise UPS3, be connected electrically in that UPS3 goes up and by the load 4 of UPS3 power supply, described UPS3 also is electrically connected with and switches cabinet 2 and magnetically levitated flywheel 7, this switching cabinet 2 is electrically connected with civil power 5 and diesel generating set 1, this switching cabinet 2 can be respectively flows to UPS3 with the power supply of civil power 5 or diesel generating set 1, carry out two-way electric energy transmitting between accumulated energy flywheel 7 energy and the UPS3, in the switching cabinet 2 supervising device 6 is installed, civil power 5, diesel generating set 1, magnetically levitated flywheel 7 all are equipped with supervising device 6 monitoring by switching in the cabinet 2.

Working method:

1, input civil power (flywheel energy storage)

Connect civil power 5, utilize vacuum pump magnetically levitated flywheel 7 state that is evacuated.Add electricity heating for magnetically levitated flywheel 7, when magnetically levitated flywheel 7 temperature reach normal value, power up startup work promptly for magnetically levitated flywheel 7, civil power 5 this moment (three-phase alternating current) is supplied with magnetic through rectification and is encouraged coil, direct current after the rectification is simultaneously supplied with magnetically levitated flywheel 7 actuating coils generation rotating magnetic field through inverter again and is made flywheel rotor work, reaches 18000 rev/mins (energy storage end) up to magnetically levitated flywheel 7 rotating speeds.At this moment magnetically levitated flywheel 7 works online and is in unloaded holding state.

2, civil power switches (instant cut-off)

When civil power 5 is switching in the power supply process (during the reclosing), be that civil power 5 inputs are can breakpoint occur the time, because magnetically levitated flywheel 7 is on-line operations, this moment, the magnetically levitated flywheel 7 of high speed rotating changed generator work output at once over to, therefore breakpoint does not appear in output, has satisfied uninterrupted power supply fully.3, (, change the diesel engine generator power supply then over to) during municipal power failure at first by the flywheel power supply

When civil power 5 breaks down, load 4 is earlier by magnetically levitated flywheel 7 power supplies, drop at 85% o'clock up to magnetically levitated flywheel 7 capacity, supervising device 6 sends instruction and starts diesel generating set 1 automatically, 3-5 changes diesel generating set 1 power supply second immediately over to, in diesel generating set 1 power supply, magnetically levitated flywheel 7 has stored energy again, and the time of magnetically levitated flywheel 7 bringing onto loads 4 will be decided according to the size of load 4.

4, the city power recovery is normal

When standby diesel-generator unit 1 operate as normal, meeting civil power 5 again, at first there is supervising device 6 will determine whether civil power 5 is normal.After confirming that civil power 5 recovers normal 120 seconds, automatically switch to civil power 5 power supplies.Diesel generating set 1 is awaited orders through 120 seconds cooling back autostops.

When 5, civil power is interfered to the protection of load

When unusual fluctuations take place in civil power 5, switch cabinet 2 with civil power 5 input automatic disconnections, change magnetically levitated flywheel 7 power supplies immediately over to, to avoid civil power 5 overtensions to cross low and to influence load 4.Therefore can reach load 4 good protective effects.

More than be that the uninterrupted power supply electric power system and the working method of the utility model flywheel energy storage are set forth; be used for helping to understand the utility model; but execution mode of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
