POWER GENERATION FACILITY, OPERATION METHOD THEREFOR, AND CONTROL DEVICE FOR POWER GENERATION FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a power generation facility capable of suppressing voltage rise of a DC transmission path while suppressing influence on a power generator, an operation method therefor and a control device for the power generation facility.SOLUTION: A power generation facility includes: at least one motor; at least one power generator configured to be driven by each of the motors; a local grid to which each of the power generators is connected; a DC transmission path provided between the local grid and a grid; an AC/DC converter for converting an AC power from the local grid into a DC power and supplying the same to the DC transmission path; a DC/AC converter for converting the DC power from the DC transmission path into an AC power and supplying the same to the grid; a first converter control unit for controlling the AC/DC converter so as to keep a voltage in the local grid at a set value or more when abnormal increase in the voltage occurs in the DC transmission path; and a motor control unit for controlling the motor so as to reduce a mechanical input from the motor to the power generator at the time of the abnormal increase in voltage in the DC transmission path.
