The world’s largest and most efficient gas turbine Grid-connected validation de-risks equipment purchases, ensures reliability and insurability
M
itsubishi Hitachi Power Systems’ T-Point 2 combined cycle power plant validation facility has entered full commercial operation with an enhanced JAC gas turbine that sets the record for output and efficiency. MHPS’ most advanced JAC gas turbine, designed for maximum efficiency and
lower emissions, is now integrated with MHPS-TOMONI® digital solutions for verification and validation at T-Point 2. The gas turbine is entering commercial operation at record-setting combined cycle efficiency greater than 64 percent and a world’s first turbine inlet temperature of 1650°C.
This gas turbine reduces carbon emissions by 65 percent compared with coal-fired plants. In addition, it has the capability for conversion from natural gas to a blend of natural gas with 30 percent renewable hydrogen to reduce emissions further. Eventually it will be capable of running on 100 percent renewable hydrogen to completely eliminate carbon emissions. MHPS demonstrates new gas turbine capabilities at its own combined cycle power plant before shipping to customers. This enables the company to provide unmatched performance, such as the 99.5 percent reliability of its J-Series gas turbines The T-Point 2 plant was commissioned in March at Takasago Works in Japan, to replace MHPS’ original T-Point plant and to continue MHPS’ approach advance the limits of technology while minimising risk to its customers. To do this, MHPS validates its new gas turbine
technologies and digital solutions under long-term grid-connected operation for a minimum of 8,000 operating hours, which is equivalent to nearly one year of normal operation and is a key insurance industry criterion for fleet reliability. The digital building blocks of the autonomous power plant being validated at T-Point 2 include an advanced Automatic Plant Startup package that is closely linked to the advanced analytics and diagnostics that continuously monitor the total plant. To validate complete remote operation, operations will be transferred from the local control room to the Takasago Remote Monitoring Center. Operations and maintenance building blocks under evaluation include an advanced array of acoustic, video, and thermographic data acquisition sensors monitored by advanced analytics that are being trained to identify pattern changes. T-Point 2 is also evaluating the first ever Netmation 4S Digital Control System to be used on an advanced class gas turbine combined cycle plant. Netmation 4S adds additional reliability, redundancy, and enhanced operator experience to the well-proven family of control systems. “This project positions us years ahead of any manufacturer in putting the latest generation of 1650°C gas turbine technology into commercial operation,” says President and CEO of MHPS Americas Paul Browning. mhps.com twitter.com/MHPS_Global linkedin.com/company/ mitsubishi-hitachi-powersystems
