Abstract

Electromagnetic transient processes in a network with a conventionally twelve-phase thyristor compensator designed to adjust the value of the starting transient current of the network in the case of direct start from the network of asynchronous motors of comparable power to the network with a jump-like change in the control angle of the thyristors in the bridges were studied. A comparison was made with such a change in the control angle of thyristors of transient currents in the circuits of a two-bridge controlled thyristor compensator with parallel connection of bridges with transient currents in a conventionally twelve-phase thyristor compensator, where these bridges are switched on in series with each other relative to the supply voltage. The advantages of the technical and economic and mass-dimensional parameters of the conventional twelve-phase converter and its operational characteristics when applied in practice in comparison with analogues are indicated.
