<p>The invention is characterized in that a remote monitoring center monitors the combustion vibratory state of the combustor in a turbine installed in a plant, e.g. a power plant. In order to monitor the combustion vibratory state, combustion vibratory data of the combustor is divided into first data acquired in real time and second data comprising representative values, in a specified period, determined from the first data. The second data is normally transmitted in a low-speed communication mode and monitored at the monitoring center. When an abnormal state is predicted as a result of monitoring the second data, the first data is transmitted in a high-speed communication mode to the monitoring center where the combustion vibratory data is monitored in detail. When a critical state is predicted, switching to a low-load operation is commanded to the site as required.</p> |
