Technical guidelines for interconnection of electrical grids in Africa

Abstract

This document provides the guidance on technical
aspects of planning, design, and operation
of an interconnected power system (IPS). An IPS
is normally large and complex because it comprises
several system operators, spanning a
wide geographical area. Grouping these system
operators into Control Areas facilitates effective
delivery of such obligations as power frequency
and tie line control, keeping of reserves,
and continuous real time monitoring, necessary
for safe, secure, stable, and reliable operations.
The document presents processes for Control
Area operations, equipment maintenance and
outage management. An IPS is often exposed
to adverse conditions that may damage equipment
and endanger staff and the public. The
document gives guidelines on implementation
of protection systems necessary for clearing
faults and handling of power system emergencies.
Measuring power flows and the quality of
power supply on interconnectors is essential for
both commercial and technical management of
power systems. Further, telecommunication is
the enabler of many power system operations
systems such as SCADA systems. This document,
therefore, gives technical guidelines on
energy metering, power quality, and telecommunications.
The document recognises the
importance of grid codes, various power system
operations requirements set by such bodies as
regional power pools, and international electrotechnical
standards. These are referenced in
many areas. Application of this document promotes
technical compliance and performance
monitoring, as required by various authorities
in the power supply sector. Lastly, this document
focuses on AC power systems and is limited
to high level technical guidance.
