Abstract: An electric power information acquisition unit (32) is provided for acquiring power supply-and-demand information including electric power acceptable to an electric power system (5) or information correlated with the electric power. A fluid information acquisition unit (17, 18) is provided for acquiring fluid information including information correlated with a physical quantity of a fluid flowing out of a channel (1). A controller (20, 30) is provided for controlling at least one of the physical quantity, the channel (1) or electric power generated or electric power to be generated by a generator (G) by using the fluid information so that the physical quantity becomes equal to a desired value, while controlling electric power to be supplied to the electric power system (5) to the electric power acceptable to the electric power system (5) or less, by using the power supply-and-demand information.

Abstract: A fluid apparatus includes a hydraulic machine, a rotary electric machine connected to the hydraulic machine, and a power conversion controller that converts power from the rotary electric machine. A non-normal operation is performed in a warning state that differs from a normal state in which a normal operation is continued and an anomalous state in which operation is stopped to continue a stopped condition.

Abstract: A hydroelectric power generation system (11) is included in a channel control system (1) including a command section (9) configured to output a command value of a flow rate or pressure of a fluid, an opening degree control unit (10) configured to calculate a target opening degree based on the command value output by the command section (9), and a motor-operated valve (7) installed in a channel (2) through which the fluid flows and configured to open and close in accordance with the target opening degree. The hydroelectric power generation system (11) is provided with a water turbine (15) disposed in the channel (2) in series or parallel with the motor-operated valve (7), a generator (16) configured to be driven by the water turbine (15), and a generator controller (17) configured to control a torque or number of rotations of the generator (16) with reference to opening degree information indicating a measured value of an actual opening degree of the motor-operated valve (7).

Abstract: A control device (20) estimates a flow rate (Q) and an effective height difference (H) of a fluid machine (W) based on a characteristic detectable with regard to a rotating electrical machine (G) and correlating with the flow rate (Q) and the effective height difference (H) of the fluid machine (W). A total flow rate (QT) in a pipe system (1) is estimated based on these values estimated by the control device (20) and a flow resistance characteristic line (S), and cooperative control of the fluid machine (W) and the flow rate control valve (6) is performed such that the estimated value of the total flow rate (QT) becomes close to a target flow rate (QT*) of the total flow rate (QT) in the pipe system (1).
