Commissioning Results of Mitsubishi Hitachi latest 50 Hz Gas Turbine Fleet (Room Rheinsaal 4)

The first M701J Gas Turbine started commercial operation on January 2016 and the second one in June 2016. With 470 MW, this is the largest gas turbine in operation in the world. These units were designed based on the successful experience of nineteen 60Hz units in operation with over 300,000 hours. The latest 50 Hz F upgrade, featuring 1,500 ⁰ C Class Turbine Inlet Temperature (TIT) for 500MW in a 1:1 combined cycle configuration has also started commercial operation at a combined cycle plant in Japan. The higher turbine inlet temperature was applied to the upgraded F design by incorporating J technology to the first two turbine stages. Two additional units were commissioned in Thailand bringing the fleet to four units in operation. A 50Hz of the H-100 gas turbine has also gone commercial in Japan. This paper presents the commissioning results of all three 50Hz frames and presents an update of the commercial operation records.
