Abstract: A condition monitoring system includes a monitoring terminal, an acceleration sensor, and a data processor. The data processor calculates a diagnostic parameter from data measured by the acceleration sensor, determines a degree of damage to a bearing or a gear included in a wind turbine generator based on the diagnostic parameter, and controls the monitoring terminal to show information indicating a degree of suppression of electric power generated by the wind turbine generator in accordance with the degree of damage to the bearing or the gear.
