Combined Cycle Power Generation

T-Point 2 is located at Takasago Machinery Works in Hyogo Prefecture, Japan.

It is the only commercially operating power plant in the world that was specifically built for validation of power solutions.

Its uniqueness is the robust long-term validation process that minimizes risk for customers and gives assurance of product performance and durability for subsequent units of the same frame.

Purposes of the T-Point 2

To validate gas turbine technologies newly applied to achieve higher efficiency, allow operations at elevated temperatures, and reduce NOx.

To validate the reliability through long-term commercial operations of the highly efficient and environmentally friendly combined-cycle power generation.

Development of T-Point

The original T-Point demonstration facility began operation in 1997 with M501G (60 Hz), which was upgraded to M501J in 2010 and M501JAC in 2015 with response to the power industry’s demand for large-scale, high-efficiency power generation.

Since the original T-Point can not satisfy the further requirement for larger capacity and higher efficiency, we made a decision to build T-Point 2.

T-Point 2 entered full commercial operation with an enhanced JAC gas turbine from July 2020.Validation of Next Generation

Combined Cycle Power Generation

With its combination of gas turbine and steam turbine,T-Point 2 is cutting edge combined cycle power plant validation facility.

By developing next-generation technologies and validating them in T-Point 2 GTCC facilities, Mitsubishi Power helps its customers world-wide attain a stable electricity supply.

Long term demonstration of off-site plant control at T-Point 2 is conducted from the Mitsubishi Power Takasago TOMONI HUB (Analytics and Performance Center). Validation operations are run to increase the reliability of the entire plant including the main equipment such as turbines as well as auxiliary equipment such as pumps and fans. In addition, various applications of a suite of intelligent solutions TOMONI™ that serve to shorten start-up time and automatically optimize operation parameters are installed in T-Point 2. Mitsubishi Power will also be training its AI applications, allowing T-Point 2 to eventually become the world’s first autonomous combined cycle power plant.

High efficiency energy through combined cycle power generation

Gas turbine combined cycle (GTCC) power plants use natural gas to deliver the cleanest and highest efficiency power generation.

Plants employing state-of-the-art gas turbines of Mitsubishi Power have a 20% higher power generation efficiency than conventional coal-fired thermal power generation systems and the world’s highest level of efficiency of more than 64%. That enables CO2 emissions an approximate 50% reduction.

What is GTCC?

In the power generation method characterized by the standalone operation of a gas turbine, known as the simple or open cycle, releases exhaust gas at temperatures of around 600℃ into the atmosphere.

Combined cycle power generation improves the general thermal efficiency of the plant by recovering this high temperature exhaust gas. Many combined cycle power generation plants adopt a waste heat recovery cycle in which exhaust gas from the gas turbine is led to the waste heat recovery boiler to generate steam using recovered heat to drive the steam turbine.

Advantages and Features that Make the GTCC the Mainstream for New Thermal Power Generation Facilities

High level of thermal efficiency

In comparison with thermal efficiency of about 40% in steam power generation, combined cycle power generation features a thermal efficiency of at least 60% (with both figures on the lower heating value basis).

Environmentally-friendly

Carbon dioxide (CO2) is released in smaller quantities into the atmosphere.

Nitrogen oxides (NOx) and sulfur oxides (SOx) are released in smaller quantities into the atmosphere.

High temperature wastewater is discharged in smaller quantities into the sea.

Mitsubishi Power’s gas turbines utilize many key cutting-edge technologies.

The gas turbine is the core component of a gas turbine combined cycle (GTCC) power plant. Mitsubishi Power has been working on the development of gas turbines for many years

Mitsubishi Power has been working on gas turbine development for many years and has integrated the latest aerodynamic, cooling design and material technologies to create a wide range of products that realize high efficiency and reliability.

This was the dawn of the current era of combined cycle power generation. the DA Series incorporates F-Class technology into the D Series to improve overall performance.

Features

Integral Design

The gas turbine units are based on a basic structure adopted in the early 1970s www.abb-drive.com that has accumulated a track record of at least 40 years. Its main features are listed below:

Compressor shaft end drive reduces the effect of thermal expansion on alignment

Rotor with simple single-shaft double bearing support

Rotor construction with bolted discs, torque pins in the compressor section and CURVIC couplings in the turbine section to ensure stable torque transmission

Axial flow exhaust structure for advantages in combined cycle plant layouts

Horizontally split housing for on-site removal of the blades with the rotor in place

Compressors

The DA series utilizes high-efficiency compressors with a proven track record. The fixed vanes of the backstage are supported by vane rings to minimize tip clearance of the rotating vanes.

Variable inlet guide vanes ensure operational stability at start-up and enhance performance under partial loads in combined cycle operation.

Combustion chamber

Mitsubishi Power introduced the world’s first commercially available dry low NOx combustor to the D-Series gas turbine in 1984.

The premixed low NOx combustor consists of a pilot burner and eight main burners surrounding it. The combustion chamber has an air bypass mechanism to adjust the fuel-air ratio in the combustion zone.

Turbine

In response to the increase in turbine inlet temperature, the fixed blades of the first three stages and the rotor blades of the first two stages are air-cooled.

The rotor blades of the fourth stage are equipped with Z-shaped shrouds to enhance the vibration strength of the blades.

The fixed blades are supported by blade rings that are independent of each stage to protect the turbine housing from thermal expansion.
