The invention relates to a quick response magnetic control electric reactor suitable for
wind power field dynamic reactive compensation. The electric reactor is improved on the basis of a common magnetic control electric reactor in the prior art, and characterized in that a damping
resistor R and an insulated gate bipolar translator (IGBT) connected with the damping
resistor R in parallel are added. The damping
resistor R is connected between the
anode of a free-wheeling
diode D1 and the
tail end D11 of a first coil L1, the IGBT is connected with the damping resistor R in parallel, and a gate
electrode G is connected with an output end of an IGBT drive
chip. The turn number between a first tap K11 and a second tap K12 is n1, a first tap ratio of the first coil L1 and a second coil L2 is
delta1 which equals to n1 / 2N and equals to 1.5-3.0%, the turn number between a third tap K21 and a fourth tap K22 is n2, and a second tap ratio of a third coil L3 and a fourth coil L4 is
delta2 which equals to n2 / 2N and equals to 15-20%. The quick response magnetic control electric reactor has the advantages that by means of the damping resistor, fast demagnetization is realized, fast dynamic response of the magnetic control electric reactor is achieved, and the magnetic control electric reactor is simple, practical, high in reliability and low in cost.
