Abstract
According to one embodiment, there is provided a variable-speed operation control apparatus of a hydroelectric power generation system including a power generator interconnected to a power system through a main circuit and a water turbine directly connected to the power generator. The apparatus includes a branch circuit branched from the main circuit and including a frequency converter which performs conversion between an output frequency of the power generator and a system frequency of the power system, wherein the power generator is interconnected to the power system through the branch circuit when a flow rate of water is less than a fixed level.
