GAS TURBINE CONTROL APPARATUS AND CONTROL SYSTEM

摘要

It is described a gas turbine control apparatus (502) comprising: first and second terminals (T1, T2), connectable to a flame sensor device (501) associable with a gas turbine (200), and structured to selectively provide a flame presence detection signal (S0N) in a flame configuration and a flame absence detection signal (S0FF) in a flame absence configuration; a status decision module (503) configured to detect a switching from the flame configuration to the flame absence configuration and produce an extinguished flame signal (SDET); and a switch module (504) operable by a test signal (STS) to simulate a switching from the flame configuration to the flame absence configuration. The gas turbine control apparatus further incudes an anomaly sensing module (505) configured to generate said test signal (STS) and sense the extinguished flame signal (SDET) to detect anomalies of the status decision module (503).
