Disturbance Detection
& Analysis for Power System
Director of the Consultaon Center, Faculty of
Engineering, Ain Shams University, Cairo, Egypt.
When a major power system disturbance
occurs, protection and control actions are
required to stop the power system degradation,
restore the system to a normal state
and minimize the impact of the disturbance.
The present control actions are not
designed for a fast-developing disturbance and
may be too slow. Local protection
systems are not able to consider the overall
system, which may be affected by
the disturbance.

Course Objectives
The fault recording equipment used in monitoring power systems
evolved from a wet trace and light beams writing on special photo
sensitive paper or film oscillograms to digital, microprocessor-based
technology. Some of the old records took days to develop, as in the case
of the wet trace and recurring problems with sensitive papers.
As a result, some key records were lost, making the analysis of power
system disturbances extremely difficult. In addition, starting recording
equipment was a hassle, causing unreliable oscillograph operations.
A digital fault recorder (DFR) is considered an intelligent electronic
device that can be accessed via communication links to send fault
records automatically to remote operating centers and engineering offices
immediately following a disturbance. This allowed a rapid analysis
to make it possible to restore the system. Accurate root-mean-square
measurements as well as a host of software packages can be executed to
verify the system model and to assess the impact of disturbances on
power system equipment.
Analysis of power system disturbances is an important function that mon-
itors the performance of a protection system. It can also provide a wealth
of valuable information regarding correct behavior of the system. Under-
standing power system phenomena can be simplified, and adoption of
safe operating limits and protective relaying practices can be enhanced.
Review of DFR and numerical relay fault records for system operations
can help to isolate incipient problems so that corrections can be imple-
mented before the problems become serious. Understanding power sys-tem oscillations and system relaying response during a power swing con-
dition can be enhanced, thus avoiding system blackouts. In addition, un-
derstanding power system engineering concepts and the use of symmet-
rical components in the analysis of power system faults can be enforced
and enhanced through DFR analysis.
Course Overview:
ogically organized, Disturbance Analysis for
ower Systems begins with an introduction to the
ower system disturbance analysis function and
s implementation. This course will guide partic-
pants through the causes and modes of clearing
f phase and ground faults occurring within pow-
r systems as well as power system phenomenand their impact on relay system performance.
The course will demonstrate how protection sys-
ems have performed in detecting and isolating
ower system disturbances in:
Generators
Transformers
Overhead transmission lines
Cable transmission line feeders
Circuit breaker failures
Language: Who should attend?
This beneficial course for Electrical Engineers and
Senior Technicians specialized in the fields of Pow-
er Quality, Operation, Design, Instrumentation, and
Analysis. In addition, the course is suitable for those
who want to get deep understanding of Power
Systems monitoring, and mitigation techniques.
The Presentation, supplied documents, and
orkshop exercises of the course are in English.
However, based on the trainees desires, use of
ilingual (English and Arabic) for oral
xplanation is available.
