【 摘 要 】

The developments in power electronics are offering new opportunities in operation of hydro power generating units. The applied load in pump and turbine operation cannot be changed easily. By using of frequency converters, the speed of the units can be changed in a defined range, without losing much efficiency. An additional benefit of such kind of concept is the improved transient performance of the entire system. In the presented paper the advantage of speed variable power generating system equipped with frequency converters are shown.
