Abstract
Volume 3 (Preparation of Specification) comprises three Modules:
 Module 4 includes the following documents:
 500 & 400 kV AC Sub-Stations – Preparation of Technical Specifications
Provides general description on the three substations (Mandaya, Kosti and Nag Hammadi) involved in the regional interconnection project between Ethiopia, Sudan and Egypt.
 Kosti Sub-Station SVC - Preparation of Technical Specs
Guideline for a turn-key specification of a complete Static Var Compensator (SVC); connected at the Kosti Substation.
Telecommunication, SCADA and Metering
Details the proposed design for telecommunications, metering and control systems; describes the functional aspects and the general specifications for remote and centralized supervision and control for Egypt-Ethiopia-Sudan inter-connection.
 500 kV AC Lines “ Design Report
Provides particular technical requirements regarding the design of the 500 kV AC overhead transmission lines from Mandaya (Ethiopia) to Kosti (Sudan).
 600 kV DC Lines – Design Report
Provides general technical considerations regarding the design of the 600 kV DC overhead transmission line from Kosti (Sudan) to Nag Hammadi (Egypt).
HVDC Main Equipment Description
Provides useful information concerning the main equipments of a HVDC station, typical HVDC losses, and a typical layout for Kosti (Sudan) and Nag Hammadi (Egypt) HVDC Stations.
 HVDC Preparation of Specifications
Provides general description on the two HVDC stations (Kosti and Nag Hammadi) involved in the regional interconnection project.
 Module 5: Operation and Maintenance
The purpose of this document is to introduce O&M strategy for all interconnection infrastructures located on the three countries Egypt, Ethiopia and Sudan. The report is divided into four sub-modules relating to the different equipment types involved by the regional interconnection project: i) O&M for 400 and 500kV substations (including SVC); ii) O&M for HVDC converter stations; iii) O&M for Overhead Lines; iv) O&M for Control systems, SCADA and metering.
Module 9: Training Final Report
This document proposes the training activities for interconnection operation. It is a complementary document, in addition to the previous technical modules. The module gathers training principles for the different infrastructure parts of interconnection. The intent is to provide operational and maintenance guidelines for future operator management and staff, in order to organize training activities before and during interconnector operation. These specifications cover alternative current substations, static var compensator facility, direct current converting stations, physical transmission lines, control centers (main and back-up) equipment and system operation teams.
