Background The DSP is a digital signal processor for short, is a microprocessor with a special structure, is specially used for processing digital signals in real time, and has the characteristics of high operation speed, high precision, high integration level and the like. The magnetically controlled reactor is one kind of reactive power compensation equipment with dynamically regulated inductance via altering the magnetic saturation of iron core. In the operation process of the power system, the balance of reactive power is a key factor for guaranteeing the power quality and the system stability. The magnetic control reactor is widely applied in the reactive compensation field by virtue of the characteristic that the inductance can be dynamically adjusted by changing the magnetic saturation of the iron core. However, once the device with a strong magnetic field exists around the magnetically controlled reactor, magnetic interference is very easy to be generated on the magnetically controlled reactor, and thus the control accuracy of the magnetically controlled reactor is reduced, which needs to be improved.
