Abstract
In applying knowledge based systems (KBS) to power system
operations the
solution
method was known first and the problem came later. This
meant that possible
uses for
expert systems in power system operations were
investigated, without a clear
target
being defined in the beginning.
Due to the rapid prototyping in KBS development, the
analysis of the problem
for a
KBS has been weak. In the switching planning project
called EKA, we faced
problems in knowledge acquisition and the design. The
problems were thought to
be
avoided by doing the problem analysis more clear and by
constructing documents
of
each phase of it.
This study introduces a systematic method for the
selection of power system
applications for KBSes. The method is based on the
assumptions that the role of
a
KBS is to support existing activities in the power system
control center and
that the
domain can be described with activities.
The study also presents a systematic approach to problem
analysis containing
two
phases:
- The role specification, in which the environment of the
problem domain and
the
modules within it are analyzed. Based on the analysis,
KBS modules are
specified.
- The KBS structure description, in which the contents of
the selected KBS
applications are described.
The proposed methods are illustrated with the
applications for switching
planning,
restoration, and fault diagnosis.
