An automatic switching equipment for the control of two 20,000-kw. frequency changer sets using the Scherbius method of load and power factor control has been in successful operation at the Page Avenue station of the Union Electric Light and Power Company of St. Louis, for almost a year. This equipment contains several new features in the automatic control of machines of this type. Besides being the first completely automatic switching equipment applied to machines of this type, it is unique in…

Generation of Wind Power using Doubly Fed Induction Generator

Due to independent controlling mechanism for the active and reactive power, doubly fed induction generator (DFIG) is still culled by the wind turbine companies. The control strategies are

The frequency changer era-interconnecting systems of varying cycles

At the start of the 20th century, the five different frequencies of 25, 30, 40, 50, and 60 cycles were in use, to a greater or lesser degree, in the United States. There was also a smattering of
