Starting in 1969 Siemens has incorporated several competitors to improve the own market position as a reaction on the market development. In consequence the Siemens product portfolio has increased. Now with the Enhanced Platform concept Siemens finalized these company associations by combining all well proven technical features from the several product lines in one common product line basis. Learn more about the Enhanced Platform concept in this paper.

The paper shows different approaches for power plants for combined heat and power. These different concepts consider the degree of utilization of fuel, different thermodynamic concepts and economic criteria of plant layout. The thermodynamic investigations include variances of steam extractions and the realization of these extractions in the water-steam-cycle.

This paper describes the need of efficiency optimization over a broad load range and the need for using the large reserve of power capacity by focusing on the comparison of the present and the expected future market. Those arguments are based on expertise and high-tech products as well as a cleary formulated strategy/plan. This also implies a highly developed design that requires measures to additionally improve operating flexibility.

Despite the current economic crisis and the increasing share of renewable energy, the long term perspective predicts an increasing global demand for nuclear and fossil fired power generation applications. In response to the growing demand of new nuclear power plants, Siemens is implementing and further developing a modular platform of half speed steam turbines and generators covering the most relevant power range from 1000 MWe up to 1900 MWe. The following product will be described in this paper: Siemens Steam Turbine Generator Packages: SST-9000 series for nuclear power plants; 1000…1900 MW.

Siemens has more than 40 years field experience with combined HP/IP steam turbines. Today, as part of the SST-5000 series the combined HP/IP steam turbine is applied in single- and multi-shaft combined cycle power plant (CCPP) configurations and in steam power plants (SPP) of up to 700 MW. Steam parameters such as temperature and pressure required for CSP plants are lower than those of fossil fired power plants and higher than the parameters of nuclear power plants. As a supplier of both fossil and nuclear steam turbines Siemens experience covers also the CSP thermodynamic range. This paper describes technology and performance of the SST-5000 series optimized for application in CSP of the 250 MW class.

A typical feature of modern generator-drive steam turbines for industrial applications in the power range up to 60 MW is the use of a gearbox between the steam turbine and the generator. The technical concept of Siemens’ SST-400 turbine, which is a modern and at the same time well-proven product, is environmentally-friendly due to the high efficiency, and the decreased materials and fabrication energy demand. In this paper the SST-400 is presented by references from Thailand, Malaysia and Turkey.

Liberalization/deregulation of the electricity market continues to expand in many parts of the world. This requires that power producer owners and operators deliver electricity more efficiently and at competitive pricing. In parallel with these market demands, the operation of the complete power plant – turbine, generator, boiler and auxiliaries – must improve reliability, availability and utilization/efficiency.

One way to achieve the objective of a flexible and short termed outage planning and to reduce the transactional costs is to establish Service Contracts between the utilities on the one side and the manufacturers on the other. These tailor made contracts should be the basis to leave the transactional business behind and to enter value based and success depending business models or contracts. Critical factors for the success were the alignment of the objectives and the definition of benchmark matrices (Score Cards) to measure the level of success. The range of this Strategic Contracts can vary from simple parts availability programs or Operating Plant Service Agreements (OPSA) to Long Term Programs (LTP) with risk sharing elements and the value based payment mentioned above.
In addition these aims could be achieved more efficiently by using intelligent condition monitoring strategies for the power plant and its key components using a supervisory on-line diagnostic system. The use of comprehensive on-line data acquisition, internet data transmission systems, task-related data analysis and an expert background knowledge base at newly founded Remote Diagnostic Center enable detailed diagnosis of the actual plant condition.

A reliable source of low-cost electricity is fundamental to a healthy economy. The current market supports both the development of new generating resources and the retrofitting of the existing infrastructure to meet the increased electrical demands. These technology retrofit solutions represent an opportunity for generating companies to quickly and cost-effectively improve their competitive position by improving the operation, performance and reliability of existing equipment. This paper describes the design and the results of the Steam Turbine Replacement Components that were supplied by Siemens Power Generation to Dairyland Power Cooperative.

Power plant market requirements have changed in recent years. The tendency for highly flexible and efficient power plants with long revision intervals, life times ≥200,000h as well as low investment costs have resulted in an increased effort in the improvement of design and materials. One possible way to meet high efficiency requirements is to install sub-critical steam power plants with live steam temperatures of T ≥565 °C and an optimized steam cycle path. As a result, new challenges have arisen for the design of a two cylinder steam turbine line for a capacity up to 700 MW.

Turbine and generator rotors undergo high stresses and, from a safety aspect, are the most significant components of a turbine generator system. Depending on the appropriate operating temperatures, the shafts can be fabricated out of low/high alloy heat resistance material or of low alloyed, highly toughened material for low pressure application.
