Optimum Operation of In-Plant Cogeneration Systems

Show full item recordAbstract
Selecting the best way to run large
in-plant cogeneration systems to meet
site electricity and steam demands at
minimum cost is a highly complex
problem. With typical annual fuel bills
of several tens of millions of dollars,
even small percentage changes in
operating efficiency can have a large
cost effect.
An advisory system which
incorporates a detailed power plant
simulation model and a mathematical
optimization package can determine the
optimum settings for control variables
of the power plant and eliminate
uncertainties associated with achieving
the minimum cost operation.
TENSA Services and their parent
company, ICI PLC, have developed and
applied systems to achieve these
optimization objectives. Both on-line
and off-line systems have been
installed. These systems can solve the
optimization problem quickly and in real
time, yielding operating costs savings
of two to six percent with short
paybacks.
An overview of these systems is
presented. Their application is
illustrated by a case study.
