Abstract |
This paper describes an orthogonal arcsuppression
coil, which has wider adjustable range, less
harmonic and easier control. Regulation of the coil
inductance adopts dynamical orthogonal coil magnetic
control, and the respond of control is fast and accurate.
Working distance from the resonance point, the orthogonal
coil monitors the capacitive current of power net, and
immediately turns into full compensation state. When
instantaneous earth fault occurs, the arc suppression coil
compensates the fault arc automatically, while a permanent
earth fault occurs, it can detects and trips the faulty
immediately and using the thyristor switched capacitors to
tune arc suppression coil sensitively. It also discuses
dynamic arc suppression coil compensation system which is
effective and correct. |
