Operation of new variable speed constant voltage and frequency generator connected to the grid

摘要

Wind is an uncontrolled and stochastic source of pwoer because its speed is continuously changing in magnitude and direction. In order to maximise the obtainable power, wind driven power systems must be able to generate pwoer at all wind speeds whether this speed is low or high. This not possible when conventional generators are used unless complicated control systems or electronic circuits are used. In this paper, the feasibility of using an AC commutator machine as a generator for wind power plants is experimentally investigated. The machine is connected as a shunt generator in parallel with the grid.
