Siemens promotes new technologies to help power plants improve power generation efficiency

Siemens is committed to developing HL class gas turbines to achieve a new generation of power generation efficiency. Recently, Siemens announced that it would verify its HL class gas turbine technology at the site of Duke energy in Lincolnshire, Northern California. Siemens developed this technology based on its mature sgt-8000h technology. Siemens' advanced HL class gas turbine combines a series of tested new technologies and the best design features derived from experience to achieve a higher level of efficiency and performance. The net power generation efficiency of HL gas turbine can exceed 63%, and the medium-term goal is to achieve a net power generation efficiency of 65%

in addition, Siemens is accelerating technological upgrading and enhancing technological competitiveness by applying newly developed key technologies to its existing gas turbine product portfolio. In the near future, customers will benefit from the further improvement of gas turbine efficiency and performance. This method is also one of a series of effective methods to help Siemens customers stand out in the rapidly changing market competition, that is, greatly shorten the delivery cycle and project construction time through standardization and modularization

Siemens' new HL class gas turbine includes three models: sgthl, sgthl and sgthl. Under single cycle operation mode, the power generation capacity of air-cooled sgt-9000hl gas turbine is 545 MW (50Hz market) and 374 MW (60Hz market) respectively. Sgthl generates 453 MW in single cycle operation mode. All three gas turbines can achieve a combined cycle efficiency of more than 63%

in order to achieve excellent performance, these three gas turbines need to work under high combustion temperature. To this end, Siemens experts have developed advanced combustion technology, innovative multi-layer coating, ultra-high efficiency internal cooling technology and water steam cycle that eventually makes plastics brittle after optimization. In addition, the optimized sealing technology can minimize the leakage of cooling medium and air. At the same time, the innovative 3D printing blade can bring higher aerodynamic efficiency to the compressor. Predefined and prefabricated solution components and pre selected suppliers and products can greatly shorten the construction time of the project and enable the project to be put into production quickly. The new gas turbine can be seamlessly connected to Siemens' digital products for power plant operators and power companies, and connected to Siemens' cloud based IOT operating system mindsphere. Through mindsphere, we can obtain valuable data analysis capabilities from Siemens and its partners, and use our insights into gas turbine operation and decision support to bring practical benefits to customers

driven by digitalization, the speed of Technological Development in the field of power generation is accelerating. Willi meixner, CEO of Siemens power generation and natural gas group, said that it took Siemens 10 years to increase the power generation efficiency of combined cycle power plants from 58% to 60% from 2000 to 2010, and 6 years to further increase it to 61.5% in 2016. Now we are breaking through the efficiency level of 63% or higher. However, we know that only the speed and efficiency of cross-border grafting of materials are not enough. The reliability and cost-effectiveness of Siemens' solutions and the support of sincere cooperation, financing and risk control are equally important for customers

in order to minimize customer risks, Siemens has comprehensively and thoroughly verified and tested HL level technology. After the component test and prototype test in Siemens, the technology is currently being tested and verified under the actual conditions of the customer's site. With the new HL class gas turbine, our customers will be ready for the digital future. Meixner added

we see the rapid development of renewable energy around the world in the International Building Exhibition held in Las Vegas, but gas-fired power plants will still play an important role in the energy structure in the coming decades, said meixner. Due to the increasing volatility of renewable energy, flexibility will become a key feature of gas turbines. Siemens' HL class gas turbine can achieve a climbing efficiency of 85 MW per minute in single cycle mode. Therefore, efficient and flexible gas turbines such as Siemens HL class are ideal for energy systems with a rapidly rising proportion of volatile renewable energy
