摘要： PROBLEM TO BE SOLVED: To easily obtain a proper power fluctuation compensation in a case that a plurality of power storing devices are arranged in a wind power generation device. SOLUTION: In this wind power generation facility in which the two power storing devices 4a, 4b are arranged in a wind power generator 1, an electric power value Pw1 supplied to the one power storing device 4a is taken in to the other power storing device 4b via a low frequency pass filter 12b thereby obtaining an electric power value Pw2 used for control in the storing device 4b. In this arrangement, a response characteristic of the lower frequency pass filter 12b is made to correspond to an electric power response of the power storing device 4a, whereby the input value Pw2 corresponds to a case that the computing in which a power control delay is simulated is applied to an electric power command value of a composite system consisting of the wind power generator 1 and the power storing device 4a. Accordingly, the proper power fluctuation compensation is obtained.

摘要： PROBLEM TO BE SOLVED: To restrain the fluctuating portion of effective power to be outputted to a system and to perform the stable charging and discharging operations of a power storing system, by letting the power storing system have the functions of absorbing or releasing the high-frequency component outputted from a wind-power generator when the power storing system is built in combination with a plurality of wind-power generating systems. SOLUTION: In a combined system of a wind-power generating system 19a and a power-storing power converting system 7a, a power storing device 4a operates in such a way as to remove the high-frequency component of the effective power Pw of the system 19a. Thus, an effective power Psvs becomes the value obtained by adding the effective power command value of the device 4a to the low-frequency component PwL of the output effective power Pw. As a result, because the effective power Pw of the system 19a is added to the effective power detection value Pc of the device 4a, the fluctuating portion of the effective power Pw can all be charged or discharged stably by the device 4a.
