Abstract
The state of combustion oscillation in the combustor of a turbine of a power plant is monitored from a remote monitoring center. To monitor the combustion oscillation state, combustion oscillation data on the combustor is separated into two types of data: the first data obtained on a real-time basis, and the second data including representative values within a predetermined period of time obtained from the first data. In the normal state, a low-speed communications mode is used to send the second data, which is monitored at the monitoring center. If an abnormal state is predicted as a result of monitoring the second data, the high-speed communications mode is used to send the first data, and more detailed combustion oscillation data is monitored at the monitoring center. When a critical state is predicted, an instruction is sent to the local site to switch the operation mode over to the low load operation mode.
