摘要： PROBLEM TO BE SOLVED: To provide a hydraulic power generation speed controller, which can avoid the output reverse response at sudden increase of load while enabling the high-speed load following property in hydraulic power generation, and a control method, and a control program. SOLUTION: The speed controller 1 is equipped with a rotational speed setter 11, a regulator 12, an integrator 13, a setting rate operation part 14, a delay filter 15, subtractors 1a-1c and an adder 1d. The subtractor 1b is used as a means which calculates an output deviation signal 23 by the difference between the generation output command signal 21 from an output controller 2 and the real power generation signal 22 from a water-wheel generator 4. The delay filter 15 is made a primary filter which generates a delay, with an output deviation signal 23 as input. The time constant of the delay filter 15 is set to several seconds or thereabouts so that it may enable high-speed load following property. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To eliminate steady difference caused by mismatch of characteristics by subtracting an r.p.m. difference from an r.p.m. command value of a pump turbine, generating a control signal for eliminating the difference thus obtained, adding the control signal to a power command value and subtracting an actual input power from the a power command value. SOLUTION: An r.p.m. command value operating section 12 calculates an r.p.m. command value of a pump turbine based on the power command value of a generator motor and the actual head of a pump turbine and a subtractor 13 subtracts the substraction results of a subtractor 14, i.e., the difference of r.p.m., from the calculated r.p.m. command value. An r.p.m. controller 15 generates a control signal for eliminating the difference of r.p.m. produced through subtraction and an adder 16 adds the control signal to the power command value of the generator motor. A subtractor 17 subtracts the actual input power from the added results of the adder 16 and outouts the power difference to the excitation control system for the motor generator.

摘要： PURPOSE:To make the output follow a generation output command smoothly without lowering generation efficiency so as to improve the stability of a power system by controlling the output directly, according to the ' output command, and also, inputting the rotational speed goal signal of an inductor to be inputted into a water supply means together with a water level signal. CONSTITUTION:The output of an inductor 1 is kept at a output command PO, using rotational operation energy first so as to make the output P follow the change of the output command Po. Furthermore, the optimum rotational speed command Na is supplied wit rotational operation energy required for adjusting the rotational speed N on the other hand by controlling a guide valve 11. Therefore, it becomes possible to settle the rotational speed N to the optimum rotational speed Na by making the output P follow the change of the output command Po quicker than the response of the guide valve 11. Accordingly, the stability of the power system can be raised by making the output follow the output command smoothly without lowering the generation efficiency.

摘要： PURPOSE:To achieve a stable AFC drive regardless of the kind of target input/ output signals by inputting a target input/output signal to a filter circuit having a determined band eliminating characteristic, and reducing frequency components as inducing the hydraulic fluctuation of a line. CONSTITUTION:A target input/output signal P* is input to a filter circuit 8. A control signal P** is used in the actual control is output from the filter circuit 8 to a variable speed control device 7. In the variable speed control device 7, the rotating speed N of the main machine in controlled based on the deviation with the actual shaft input/output P in a generator motor 6, changing the shaft input/output P of the generator motor 6. Then, in the filter circuit 8, a determined frequency characteristic is possessed, and the determined frequency component in the target input/output signal P* is attenuated to a determined gain. Hence, the frequency components as inducing the hydraulic fluctuation of the line in the target input/output signal P* are reduced.

摘要： PURPOSE:To prevent a trouble caused in use of an electric power system in advance, by producing a rotating speed increase command or a rotating speed decrease command when outputs from respective generators are greater than a set upper limit output or less than a set lower limit output. CONSTITUTION:A generator output sensor 11 provided with a generator 10 produces a rotating speed increase command or a rotating speed decrease command when an output from the generator 10 is greater than a set upper limit output or less than a set lower limit output. With the arrangement, a turbine is prevented from being in motor operation or in excessively loaded operation when operation of the other generator is changed so that the turbine and facilities provided with it are prevented from being damaged by an abnormal operating condition, whereby a trouble caused in use of an electric power system can be prevented in advance.
