Abstract
A power conversion device is connected to a power transmission line which is connected to a generator. The power conversion device includes a frequency detector that detects a system frequency, the system frequency being a frequency of an AC voltage on the power transmission line, a controller that generates a reactive power command value to compensate for a variation in the detected system frequency, and a power converter that outputs reactive power in accordance with the reactive power command value to the power transmission line.
