Examples for the regimes of operation for a solarthermal power plant, with a power output of 50 MW:
As market leader in industrial steam turbines, Siemens commands a comprehensive product portfolio for solar thermal plants, covering the full range from 1.5 MW to more than 250 MW.
CSP plants require steam turbines which are optimized for their complex and challenging cycle conditions. Bearing in mind that efficiency and total cost of ownership are key to any investment decision, Siemens incorporates its operational experience into extensive R&D and engineering activities to adapt the turbines to the specific requirements of the CSP technology.
Day and night cycle often requires a large number of starts and fast daily startup capabilities from CSP steam turbines. When focusing on annual power production, the short start-up times of the turbines are of great benefit to the CSP plant owner. Daily cycling and temperature variations require special attention.
Reheat solutions improve efficiency and reduce problems with erosion/corrosion and moisture in the LP turbine. Siemens steam turbines meet all customer requirements for economic installation and operation and provide excellent flexibility for all cycling conditions. The turbines are suitable for higher steam parameters and can be operated in non-reheat, single reheat and double reheat cycles.
Siemens steam turbines are tailored to the customer requirements and shipped assembled for easy installation at site. This reduces time and manpower in the installation phase. All steam turbines are available with axial or radial exhaust and suitable for air- and water-cooled plants.
Siemens provides optimal instrumentation and controls (I&C) design for CSP & Hybrid-PV plants for achieving the full dispatchability of solar energy power plants. With start-up and shut-down 365 days a year, high demands are placed on your plant even on the sunniest of days. Thanks to Siemens’ I&C’s integration expertise in steam turbine controls, balance-of-plant, and solar fields the plant’s performance is optimized and long-term reliability is maintained.
Siemens industrial steam turbines for solar solutions are ordered by customers all over the world and provide energy at CSP plants in the US, Spain, Germany, India and Northern Africa.
