| description | PROBLEM TO BE SOLVED: To provide a reactive power compensation device in which an entire distribution system holds a voltage within a constant proper range.SOLUTION: A reactive power compensation device 31 stabilizes a voltage of a distribution system by controlling a reactive power that is injected into the distribution system, based on a voltage command reference value 14 and measurement information of the distribution system. The reactive power compensation device 31 further includes a voltage command correction circuit 21 which has a power current calculation function that uses a distribution line model of the distribution system. The measurement information of the distribution system at a point different from the installation point of the reactive power compensation device 31 is inputted into the voltage command correction circuit 21. The power current calculation is made based on the measurement information of the distribution system. In order that the voltage of the entire power system comes to be within a constant range, the voltage command reference value 14 is corrected with the output of a voltage command correction amount of the voltage command correction circuit 21. |
