Description
Technical field
The present invention relates to transformer DC magnetic bias current field, more particularly, to a kind of transformer DC magnetic bias current manager
Method and device.
Background technology
HVDC transmission system (HVDC) is national grid, the important component part of south electric network power transmission network, just
When often running, the path of DC current is positive and negative two polar curves.Actually it is by the monopolar ground return of two independent operatings
System is constituted.The sense of current in ground return circuit for the positive and negative polarities is contrary, and earth current is the difference of bipolar current.Appoint in bipolar
The one one pole transmission system that extremely all can constitute an independent operating, bipolar voltage and current can be unequal.Bipolar voltage
It is referred to as bipolar symmetrical operation mode when all equal with electric current, when unequal, be referred to as the asymmetric operation mode of voltage or electric current.When
In bipolar a pole break down stoppage in transit when, another extremely can with the earth constitute the monopolar ground return method of operation.Work as bipolar current
When equal, in ground, no current flows through, actually the out-of-balance current at only the two poles of the earth, typically smaller than the 1% of rated current.When bipolar
During electric current asymmetric operation, the electric current in the two poles of the earth is unequal, and earth current is the difference of bipolar current.When using one pole the earth time
During the line method of operation, DC current injects the earth by earthing pole, and the earth constitutes the part in loop, and earth current is straight
The electric current of stream transmission of electricity conveying.
After excitation current waveform is distorted, neither being symmetrical in initial point, also asymmetric in Y-axis, after Fourier decomposition, remove
Containing outside 1,3,5 ... odd harmonics, also contain 0,2,4 ... even-order harmonics.The change of exciting current amplitude and waveform is to transformation
The impact of device is mainly manifested in the following aspects.
1st, noise, vibration increase.The noise of transformator essentially from the magnetostriction of iron core, in periodically variable magnetic field
Under effect, stalloy changes the size of oneself, causes vibration and noise.The vibration that magnetostriction produces is non-sinusoidal, noise
Frequency spectrum contain multiple harmonic components.Because transformer noise frequency changes, may tie with transformator because of a certain frequency
Structure part occurs resonance so that noise is increased.When height starts direct current with monopolar ground circuit operation mode conveying power for 750MW, through scene
Test 220kV spring city substation transformer neutral point direct current is 34A, and noise reaches 94dB, increases about 19dB.
The problem that the high vibration that D.C. magnetic biasing causes is brought in itself to transformator is more serious than noise, may result in change
Inside and outside depressor, associated components loosen, for example, axial pressing plate, nail pressing, arm-tie, fang bolt etc..Coil insulation can be worn and torn, from long-term
From the point of view of, larger infringement is had to transformer insulated, resistance to shorting impact capacity.
2nd, voltage waveform degenerates.When iron core is operated in serious saturation region, leakage magnetic flux can increase, and makes electricity to a certain extent
Pressure crest flattens, and harmonic voltage, voltage total harmonic distortion factor increase.During Xingan direct current pole II is debugged, through on-the-spot test,
220kV woods benefit station #1 neutral point of main transformer DC current is when increasing to 25.7A by 1.6A, 220kV side voltage total harmonic distortion factor by
0.6% rises to 1.7%, close to the limit value of GB 2.0%.And in direct current transportation monopolar ground circuit operation mode run duration,
Repeatedly there is 35kV side capacitors bulge, explosion accident in Guangdong, through analysis precisely due to transformator is operated in zone of saturation and produces
So that capacitor bank is due to 6% reactor of connecting, actual be 5 filter branch to raw a large amount of harmonic waves, causes harmonic wave because resonance amplifies
Excessively stream and lead to.
3rd, copper loss, iron loss increase.In the presence of D.C. magnetic biasing, transformer magnetizing current may increase considerably, because
The basic copper loss of this transformator may be increased dramatically.In the same manner, because exciting current enters the saturation region of magnetization curve so that ferrum
The permeability of core and air is close, thus leading to the leakage field of transformator to greatly increase.Stray transformer flux leads to can be through connection sheet, folder
The components such as part, fuel tank, and produce eddy-current loss, i.e. additional iron loss wherein.
At present, DC current of the prior art management monitoring system is by having DC current monitoring device and monitoring main website
Constitute, only the data of DC current monitoring device is acquired and manages, single function, only relate to partial data statistics work(
