摘要： A method for detecting a water induction in a steam turbine is provided to be determined with a reliability when an inflow of water is generated at the steam turbine. A method for detecting a water induction in a steam turbine includes the steps of: starting at anyone of a DWATT(102), a Temp Tag(104), and a TTSSH(106), wherein the DWATT detects an output power of the steam turbine, the Temp Tag detects a temperature of a steam line, and the TTSSH detects a temperature of a steam seal system; performing a logical summation process at an AND block(110) for input values from a block(108) and a block(116); progressing to a block(118) when both of the blocks are determined as "yes" and determining as the water introduction is estimated in the steam turbine, wherein the water induction is detected by using data from the Temp Tag only or using data from the Temp Tag and the DWATT together, using data from the TTSSH only, or using data from the Temp Tag, the DWATT, and the TTSSH altogether; and determining whether the TTSSH temperature is dropped below a prescribed temperature at a determination block(120) or the TTSSH temperature is maintained stably during a prescribed time.
