ACTIVE AND REACTIVE LOAD CONTROL FOR CONVERTERS INTERCONNECTING 50 AND 16 2/3 HZ SYSTEMS, USING A STATIC FREQUENCY CHANGER CASCADE

The article describes a converter interconnecting two power systems operating at different frequencies and with different numbers of phases, the ratio of whose frequencies may also vary within certain limits. In general such converter stations are employed in countries where the railways employ a frequency of 16 2/3 Hz and obtain some or all of their power from the industrial 50 Hz system, as they do in Switzerland, The Federal Republic of Germany, the German Democratic Republic, Austria and Norway are discussed. The basic principles of system interconnection, with a 16 2/3 Hz synchronous generator, a 50 Hz slipring motor, a static frequency changer cascade and the electric control system are discussed. The mode of operation of the drive motor, the controlling frequency changer and the main components of the control system is outlined. Special attention is paid to the characteristics of the interconnection and to means of detecting faults in the electronic equipment.
