After successfully designing and manufacturing the first 376 MW hydrogen-cooled Class F generator, MAPNA Generator Engineering and Manufacturing Co. (PARS) has unveiled this major achievement in a ceremony.
MAPNA PARS managed to overcome numerous supply chain and production challenges by relying on the expertise of its specialists and robust production infrastructure. Throughout the manufacturing process, rigorous quality tests and evaluations were conducted in compliance with international standards and a meticulously defined Test Plan, ensuring the generator met all required quality certifications.
The generator, model MGS72-SH2 50Hz, adheres to IEC standards and utilizes hydrogen gas for cooling, a feature that significantly enhances its performance. Compared to traditional air-cooled generators of similar size, the hydrogen-cooled design boasts an 88% higher output capacity. This innovative cooling method also allows the generator to be integrated with both gas and steam turbines, making it a versatile solution for modern power plants.
However, the use of hydrogen gas introduces unique challenges, particularly in ensuring the generator’s sealing integrity. To address this, MAPNA PARS conducted extensive air and water leakage tests, in addition to employing advanced sealing techniques, including the use of oil.
The generator’s rotor dynamics were designed in accordance with ISO standards, focusing on minimizing vibrations during operation. Additionally, the unit meets all other relevant standards for thermal generators, further solidifying its position as a state-of-the-art power generation solution.
This breakthrough underscores MAPNA’s commitment to innovation and its ability to deliver high-performance, sustainable energy solutions.
