Technical field
The utility model relates to a kind of full power convertor power test platform.
Background technology
Current transformer, as the interface of wind-power electricity generation and electrical network, should be controlled aerogenerator, carries the high-quality electric energy to electrical network again, therefore guarantees that the test job of its superperformance seems particularly important.
Existing power test platform as shown in Figure 1, by motor, motor side adapter transformer, direct motor drive for, current transformer, generator, generating pusher side adapter transformer, tested current transformer, control desk and the controller switching equipment of being correlated with form.Start prime mover operation by current transformer for prime mover driven during test, the moving blade of simulation wind and the generator that causes rotates, the electric energy of generator is fed back to electrical network through current transformer and isolation adapter transformer.In current transformer full power test process, need motor to possess equal capacity, the equipment needed is many, and the occupation of land space is large, and equipment investment cost is high.And after going into operation with the product mass, still use the test of being dispatched from the factory of this platform, accelerated the aging speed of platform device, improved testing cost.
The utility model content
The purpose of this utility model is to provide a kind of full power convertor power test platform of equivalence, has both met the power test demand, has reduced equipment investment cost again and place takies demand, and is conducive to the mass product test.
The utility model is comprised of isolating transformer, reactor and isolating switch.The first reactor is connected with the first isolating transformer through the 4th isolating switch, and the first isolating transformer is connected with external electrical network through the second isolating switch, forms a set of power path of the motor side of full power convertor to be measured; The second reactor is connected with the second isolating transformer through the 5th isolating switch, and the second isolating transformer is connected with external electrical network through the 3rd isolating switch, forms the another set of power path of the motor side of full power convertor to be measured; During test, the grid side of full power convertor to be measured is connected with external electrical network, the motor side of full power convertor to be measured is connected with the second reactor with the first reactor respectively, energy is passed to the grid side of full power convertor to be measured by the motor side of described full power convertor to be measured, be back to the motor side current transformer via isolating switch, isolating transformer, isolating switch and reactor again, form the power cycle loop, saved expensive motor device.
The utility model is applied to full power convertor ground debugging and testing process, can carry out full power test, temperature rise test, overload test and stability running test.
The accompanying drawing explanation
The existing full power convertor power test of Fig. 1 platform schematic diagram;
The test platform electrical block diagram of Fig. 2 a kind of embodiment of the present utility model;
Embodiment
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, the utility model comprises: the first isolating transformer T1, the second isolating transformer T2, the first reactor L1, the second reactor L2, and five circuit breaker Q 1～Q5 of the first isolating switch to the five isolating switch.
Reactor is connected with isolating transformer through isolating switch, and isolating transformer is connected with external electrical network through isolating switch.During test, the grid side of full power convertor to be measured is connected with external electrical network, the motor side of full power convertor to be measured is connected with reactor, energy is passed to the grid side of full power convertor to be measured by the motor side of full power convertor to be measured, then is back to the motor side of full power convertor to be measured via isolating switch, isolating transformer, isolating switch and reactor.As shown in Figure 2, the first reactor L1, the 4th circuit breaker Q 4, the first isolating transformer T1 and the second circuit breaker Q 2 are followed in series to form a set of power path of the motor side of full power convertor to be measured, and the second reactor L2, the 5th circuit breaker Q 5, the second isolating transformer T2 and the 3rd circuit breaker Q 3 are composed in series the another set of power path of the motor side of full power convertor to be measured successively.Two cover power paths are connected in parallel on the both sides of full power convertor.The first circuit breaker Q 1 is connected between the grid side and external electrical network of full power convertor to be measured.
Tested object of the present utility model is the wind power generating set full power convertor, the pusher side of full power convertor adopts double winding more, and for the electric current of designing requirement can be provided, the circuit structure of test platform as shown in Figure 2, pure meritorious circulation can meet power test, without Reactive Power Device.Active current is along pusher side → net side → isolating transformer → reactor circulation, and active current can be passed through the pusher side programmed control.
The effect of isolating transformer is the circulation of blocking-up net side and pusher side.Because net side and pusher side brachium pontis are to control separately, there is zero vector in the PWM control procedure, make machine net side brachium pontis standard-sized sheet in a certain switch periods lead to and formation circulation.Circulation has increased device loss, also may produce harmonic distortion, therefore needs to use isolating transformer to eliminate circulation channel on hardware.
Reactor has the effect of transferring energy, restriction harmonic wave and balance isolating transformer secondary and pusher side inverter bridge terminal voltage.
Isolating switch is as the circuit controls switch.
The utlity model has following characteristics:
During test, first supply with the net side 690V power supply of full power convertor to be measured, the soft net side converter that opens, set up DC bus-bar voltage; Resupply the pusher side current transformer power supply of full power convertor to be measured, by the pusher side current transformer, control active current, be loaded on gradually rated current.
In a specific embodiment, take the 2MW full power convertor as example, pusher side list cover winding active current is 1000A under normal circumstances, consider that surplus the first isolating transformer T1, the second isolating transformer T2 choose 690V/690V capacity 2MVA, the 4th circuit breaker Q 4, the 5th circuit breaker Q 5 are chosen 1600A, the second circuit breaker Q 2, the 3rd circuit breaker Q 3 are chosen 2000A, and the first circuit breaker Q 1 be connected with electrical network is selected 2000A.
The selection principle of reactor L, when inductance value hour, in electric current, the higher harmonic current amplitude can be larger; When inductance value is excessive, dynamic response is fast not again, affects current tracking speed, and volume and cost all can increase.Consider two aspect factors, it is 0.15mH/1500A that this test platform list cover pusher side winding is selected the first reactor L1, the second reactor L2.
