If a little reactive powers will be unreasonable by generator offer and Long Distant Transmit, generally also impossible.Reasonably
Method is exactly to generate reactive power in the place for needing reactive power, that is, increases reactive power compensating apparatus and device.
However, the application due to modem semi-conductor devices is more and more universal, power also bigger, but its negative effect is exactly
Prodigious non-sinusoidal current is generated, the harmonic voltage of power grid is made to increase, aberration rate increases, and grid supply quality degenerates.If for
There are larger harmonic voltage, especially 5 times or more in electric line, these harmonic waves will be amplified by compensation device.Capacitor group and line
Road series resonance makes the voltage on circuit, current distortion rate increase, it is most likely that cause equipment damage, mend in this case
It is unusable to repay device.
