Abstract
The utility model relates to a variable frequency speed-regulating power feedback energy-saving test system which comprises a variable frequency regulating and controlling motor, a synchronous phase modulation and load modulation motor and a tested electric generator that are sequentially connected in series; and the system also comprises a testing control platform which is communicated with the variable frequency regulating and controlling motor, the synchronous phase modulation and load modulation motor and the tested electric generator. The variable frequency speed-regulating power feedback energy-saving test system feeds back the energy sent out when the tested electric generator is tested into the motor which drives the tested electric generator and is connected with the tested electric generator in a coaxial way, so that full-load test of the electric generator with high power can be completed with low power, a great deal of production cost is saved for enterprises, and the system is energy-saving and has high efficiency.
Description
Technical field
The utility model relates to a kind of performance detecting system of generator, relates in particular to a kind of frequency control type power back off saving energy test system.
Background technology
Generator is a kind of device that mechanical energy is converted into electric energy, the size of the power of its output and the height of efficient are the cardinal tasks that each purchaser is concerned about, after a generator designs is finished and is produced product, in order accurately to measure its power supply capacity under full load conditions, usually traditional method is with an enough powerful prime mover generator drive to be generated electricity, the electric energy that sends generates heat by making heaters such as resistance wire, form with heat energy loses, consumed a large amount of energy (as: fuel oils in the whole process, electric energy etc.), the electric energy of output is also by in vain waste, be unfavorable for energy-conserving and environment-protective, also increased the production cost of enterprise.
The utility model content
The utility model is in order to overcome the above problems the frequency control type power back off saving energy test system that a kind of energy-conservation, efficient, environmental protection is provided.
The technical solution of the utility model is: include the frequency conversion control motor of series connection successively, synchronous phase modulation accent live motivation and tested generator, also include monitoring and control unit, monitoring and control unit is connected with former three.
The energy that the utility model sends by with tested generator test the time feed back to drive it and with its coaxial motor that is connected, frequency-conversion and speed-regulation motor is by its rotating speed of Frequency Converter Control, speed adjustable range can be applicable to the generator that drives different rated speeds from 500～5000r/min.Tested generator and the loss of phase modulation accent live motivation are synchronously supplied with by compensation frequency conversion control motor.So just can realize, just finish the full load of very powerful generator with very little power and test,, greatly save the energy as just can finish the full load test of 1000KW generator with the frequency conversion control motor of 100KW.If the generator calculations of producing 50 100KW every day according to my company average, but work in 8 hours is saves energy 50*100*8=40000 degree just, economize on the use of funds every year: ten thousand yuan of (annual 52 weeks of 40000*0.7*5*52=728, calculate by work in 5 days weekly), save a large amount of production costs, efficient energy-saving to enterprise.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is the frequency conversion control motor among the figure, the 2nd, and synchronous phase modulation is transferred live motivation, the 3rd, tested generator, the 4th, monitoring and control unit.
Embodiment
Frequency control type power back off saving energy test system includes the frequency conversion control motor 1 of series connection successively, synchronous phase modulation accent live motivation 2 and tested generator 3, also includes monitoring and control unit 4, and monitoring and control unit 4 is connected with former three.After system's starting, after frequency conversion control motor 1 drives synchronous phase modulation simultaneously and transfers live motivation 2, tested generator 3 to reach rated speed as original power, tested generator for electricity generation is normal, phase modulation transfers live motivation 2 by the external direct current power supply excitation synchronously, also begin generating, regulating this exciting current size makes synchronous phase modulation transfer live motivation 2 voltage swings and tested generator 3 to keep identical, regulate synchronous phase modulation simultaneously and transfer the phase place of live motivation 2, make itself and tested generator 3 keep identical.This moment, phase modulation transferred the voltage of live motivation 2, tested generator 3 all identical from size, phase sequence, phase place synchronously, possessed the parallel operation condition, with the two parallel operation.Continue to regulate the phase place that synchronous phase modulation is transferred live motivation 2 after the parallel operation, the phase angle difference of itself and tested generator 3 is increased, be equivalent to the power of tested generator 3 is passed to synchronous phase modulation accent live motivation 2, regulate synchronous phase modulation again and transfer the excitation of live motivation 2, keep COS φ (power factor) value of tested generator 3 to be ratings, so just equal to transfer live motivation 2 to be transformed into synchronous motor synchronous phase modulation, energy comes from tested generator 3, by frequency conversion control motor 1 and the tested generator 3 of phase modulation accent live motivation 2 common drivings synchronously, the load that synchronous phase modulation accent live motivation 2 is tested generator 3 is again the power of its driving, and the transmission of whole power is all write down automatically and formed by monitoring and control unit 4 computer test systems and reports.
Claims (1)
1. frequency control type power back off saving energy test system is characterized in that: include the frequency conversion control motor of series connection successively, synchronous phase modulation accent live motivation and tested generator, also include monitoring and control unit, monitoring and control unit is connected with former three.
