论文已在中国上海举行的2013年CIMAC大会上发表，论文的版权归CIMAC所有。Mitsubishi Heavy Industries, Ltd.(MHI) developed a 1100℃ turbine inlet temperature D-type gas turbine in the 1980s and constructed the world's first successful large-scale combined cycle power plant. Since then, MHI has developed the F and Gtype gas turbines with higher turbine inlet temperature and has delivered these units worldwide accumulating successful commercial operations. Since 2004, MHI has been participating in a Japanese Government funded project called the Japanese National Project. This project is still ongoing and targets combined cycle efficiencies in the 62 to 65% range through the development of innovative technology. The gas turbine for this National Project is expected to operate at a Turbine Inlet Temperature of 1,700℃. MHI recently developed a 1600℃ turbine inlet temperature J-series gas turbine (M501Jand M701J for 60Hz and 50Hz respectively), utilizing some of the advanced technologies developed in the Japanese National Project. This new frame is expected to achieve higher combined cycle efficiency and will contribute to reduce CO2 emissions. The target combined cycle efficiency of the J series gas turbine will be above 61.5%(gross, ISO standard condition, LHV) and the lon1 combined cycle output will reach 470MW for 60Hz engine and 680MW for 50Hz engine. This new engine incorporates:1) A high pressure ratio compressor based on the advanced M501H compressor, which was verified during the M501H development in 1999 and 2001.2) Steam cooled combustor, which has accumulated extensive experience in the MHI G engine (>1,356,000 actual operating hours).3) State-of-art turbine designs developed through the 1700℃ gas turbine component technology development program in the Japanese National Project for high temperature components. The M501J started commissioning in February 2011 at the MHI demonstration plant, T-Point, in Takasago, Japan. Upon completion of numerous commissioning tests including measurement of more than 2,300 temporary data points, and a thorough inspection of the hard-ware, the unit went commercial on July 1,2011. As of March 2012, M501Jat T-point had accumulated more than 5300 actual operating hours and 62 starts. The first of six M501J for a Japanese project was already shipped in Dec.2011, and scheduled to go commercial operation in 2013. An additional ten M501J have been sold in Korea.M701J is a 50Hz version of J series gas turbine. It was designed as a full scale of M501J with useful feedback from M501Joperation and test result at T-point.M701J will be ready for de-livery in 2014. This paper discusses the technical features and the updated status of the J series gas turbine, especially the operating condition of the M501J gas turbine in the MHI demonstration plant, T-Point.
