The invention discloses a magnetically controlled reactor capable of rapid excitation and demagnetization, an improvement of traditional magnetically controlled reactors. The magnetically controlled reactor includes a first coil, a second coil which wind around a first iron core, a third coil and a fourth coil which wind around a second iron core, wherein the first, the second, the third, and the fourth coil separately introduce a tapped point. Two tapped points of different coils on the same iron core are connected therebetween through a working circuit. Different coils on the same iron core are connected therebetween through an excitation circuit. The same coil is connected to a demagnetization circuit. The magnetically controlled reactor also includes a controller which is intended for transmitting a control signal to control the working states of the normal working circuit, the excitation circuit and the demagnetization circuit. According to the invention, the magnetically controlled reactor has multiplied winding turns when operated at the rapid excitation mode or the rapid demagnetization mode than the winding turns when operated at the normal working mode, by increasing or reducing the current in a DC loop, realizes rapid excitation and demagnetization, and greatly increases responding speed of magnetically controlled reactors.
Description
technical field [0001] The invention relates to a magnetically controlled reactor capable of rapid excitation and demagnetization. Background technique [0002] Magnetically controlled reactor, referred to as MCR, is a shunt reactor with adjustable capacity, which is mainly used for reactive power compensation of power system. The basic working principle of MCR is to change the magnitude of the DC excitation current by changing the firing angle of the thyristor, and then control the saturation degree of the iron core to achieve smooth adjustment of reactance, and finally achieve the purpose of smooth adjustment of reactor reactive power. [0003] In 1986, scholars from the former Soviet Union proposed a new structure of magnetron reactors, which made a breakthrough in the development of controllable reactors. The new controllable reactor can be applied to the power grid of any voltage level up to 1150KV as a continuously adjustable reactive power compensation device, so it ...
