Motoring control for hydraulic pump-turbine |
摘要 |
A prime mover control apparatus for controlling a primer mover including a pump turbine or a water turbine driving a generator to be synchronously connected to a power system, is disclosed. In this control apparatus, immediately after the synchronous connection of the generator to the power system, the opening of the guide vanes of the turbine is increased to exceed a predetermined value at which the turbine is not placed in the motoring mode, and then, the speed governor is controlled to drive the turbine at the speed corresponding to the standard frequency of the voltage in the power system.
