To meet with the ever-enhancing load demands, new transmission lines should be bolted-on in the existing power system but the economic and environmental concerns are major constraints to this addition. Hence utilities have to rely on the existent power system infrastructure with some modifications. To enhance controllability and boost power transfer potential of the existing power system the us...

In the modern world, electric drive has tasks of different nature, depending on application and technological process. At moment, induction drives, which operate by direct start, are widely used. This method negative factors: high starting currents at launch; impact loads mechanical system. During continuous running mode motor with its resource system is reduced. Thyristor voltage regulators us...

− Power quality measurement analysis of the electrostatic precipitator in thermal power plant under different working conditions is presented in the paper. Control of electrostatic precipitator is realized by digitally controlled antiparallel thyristors. In the first regime (continual) the constant firing angle of thyristor is set in dependence of the reference current. In other regime (intermi...
