Abstract: The use of Knowledge-Based Systems (KBS) in Power System Control Centres is today recognised as a good way to
provide Control Center operators with decision support tools. Power Systems can be considered as an important field of application of
Knowledge-Based Systems not only because of the high number of applications but also because of the challenge that Power System
application usually represent to the development of this kind of applications. This is perhaps the right time to make a balance of the success of
these applications and to use the acquired experience to learn some lessons for the future.
In this paper, we present the experience of developing SPARSE, a Knowledge-Based System for assisting Portuguese Transmission Control
Center operators in incident analysis and power restoration. Based on our experience, the reasons that contribute for the success or for the failure
of such a project are discussed.
Keywords: Control Centers, Experts, Knowledge, Knowledge-Based Systems, Real time
1. INTRODUCTION
Modern Power System Control Centres (CC) operate and
control medium and large electrical networks using real-time
information acquired trough a complex SCADA (Supervisory
Control and Data Acquisition) system. Some years ago, a new
generation of computer applications started to be included in
these Control Centres in addition to the traditional computer
applications as load flow, state estimation, contingency analysis
and short-circuit analysis. This new generation of computer
applications is based on Artificial Intelligence techniques and its
main goal is to support operators in decision making.
The use of these intelligent applications is especially
important under incident conditions when a huge volume of
information can arrive to the Control Center making Control
Center operator tasks very complex. Among intelligent
applications, Knowledge-Based Systems (KBS) play a very
important role corresponding to some important and successful
achievements.
More than a decade after the first intelligent applications has
been proposed for Power Systems [Wol-86], a lot of other
applications have been developed all over the world [Cig-93]
and Power Systems can be considered an important field for intelligent applications, especially for Knowledge-Based
Systems and Expert Systems [Dur-96].
This is perhaps the right time to make a balance of the
success of these applications and to use the acquired
experience to learn some lessons for the future [Val-96b].
In this paper, we present the experience of developing
SPARSE, a Knowledge-Based System for assisting
Portuguese Transmission Control Center operators in incident
analysis and power restoration. Based on our experience, the
reasons that contribute for the success or for the failure of such
a project are discussed.
2. KNOWLEDGE AS THE MAIN PROBLEM OF KBS
KBS are recognised as having many advantages when
compared to traditional computer applications but their most
