Introduction

Aligning plant operations with frequently changing market demands

Optimizing processes in the power plant is one of the most demanding tasks of all. Especially if it is to be achieved without costly mechanical modifications such as major conversions to a steam generator and turbine.   With Siemens Plant Optimizer, part of the Omnivise Digital Services portfolio, we use a software-oriented approach with more than ten years of proven success. Already being used in many new plants, Siemens Plant Optimizer is also being implemented during scheduled plant modernization, where operators are looking to bring plants into line with current demanding market environments.

Plant Optimizer for Steam Power Plants

High flexibility is increasingly demanded especially in the liberalized markets. Siemens Plant Optimizer enhances flexibility to enable optimal reactions to changing power demands. The basis for simultaneously flexible and stable operation are advanced control concepts.

 

Achieveing high efficiency through optimized controls is well proven strategy in power plants of all types all over the world. Siemens Plant Optimizer optimizes the overall cycle efficiency thanks to better utilization of the power plant unit. For example, by reducing throttling losses and optimizing the combustion air, the steam temperatures or the circulating water temperature, plants achieve higher performance.

 

High availability through less stress. Thanks to its predictive feedforward control and mobilization of stored energy, Siemens Plant Optimizer solution enables stable and precise load changes with minimum fuel overshoot. This minimizes wear and tear on the plant components.

 

Low emissions are achieved through an increase in efficiency which yields a simultaneous reduction in CO2 emissions.

Plant Optimizer for Combined Cycle Power Plants

High efficiency by optimized controls is well proven in power plant of all kinds all over the world. Siemens Plant Optimizer optimizes the overall cycle efficiency thanks to better utilization of the power plant unit, e.g. by the optimal trimming of the gas turbines and the supplementary firing, the increase of steam temperature or optimizing of the cold end of the steam turbine.

High flexibility is increasingly demanded especially in the liberalized markets. Siemens Plant Optimizer for enhancing flexibility allows optimal reactions to changing power demands. Basis for the simultaneously flexible and stable operation are control concepts with the respective increments for the increase of maximum load. Additionally Siemens developed Flex-Power Services™ for a wide range of changed operational requirements.

High availability through less stress. The feedforward control consistently implemented in the Siemens Plant Optimizer allows fuel overfiring to be reduced and the number of control actions to be kept to a minimum. This helps to reduce service life consumption effects on components.

Low emissions: Plant Optimizer continuously measures emissions and reduces these by precise adjustment of fuel and air flow together with optimum settings for the separate burners.
