METHOD FOR REMOTE MONITORING OF GAS TURBINE |
摘要 |
The present invention is characterized in that the state of combustion oscillation in the combustor of a turbine of a plant such as a power plant is monitored from a remote monitoring center. To monitor combustion oscillation state, combustion oscillation data on the combustor is separated into two types of data; (1) the first data obtained on a real-time basis, and (2) the second data consisting of 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, whenever required. |
