ABB built 3 x 220 kV turnkey GIS substations for EWA*, including IEC 61850-compliant substation automation systems and a modern telecommunications system**
The Electricity and Water Authority of Bahrain (EWA)* entrusted ABB with the realization of three new 220kV substations within a turnkey project:
Maximum operational safety and environmental friendliness of compact GIS with state-of-the-art substation automation, control and protection Optimal life cycle management and low life cycle cost through future-proof SA systems based on key features of IEC 61850 High reliability and security of the communication network to the National Control Centre (NCC) for telecontrol and of the equipment for teleprotection**
These are the first 220 kV
GIS substations that
ABB has built for EWA.
The latest technologies
implemented in these
projects go a long way in
helping EWA to reinforce
its grid and support it in
achieving reliability and
efficiency improvements
in daily operation. ABB’s
state-of-the-art portfolio
as well as the long expe-
rience in the substation
domain has convinced
EWA fully.

Structure of ABB’s SAS 690 Advanced Substation Automation System
* Electricity and Water Authority of Bahrain (EWA) ** Telecommunications system supplied via main contractor Japan AE Power Systems Corp.
The kingdom of Bahrain
comprises an archipelago of
665 km2 in the Persian Gulf
and has around 700’000
inhabitants. The country
is striving on petroleum
processing and refining,
aluminium smelting as well
as on its sizeable international
banking sector. It is also a fine
tourist destination. The Bahraini
Electricity and Water Authority
(EWA) takes care of the
country’s power system and
ensures that it meets the
growing demands for a high
quality energy supply. EWA
continuously invests in the ex-
pansion and stabilization of its
transmission and distribution
grid.
On the primary side, ABB supplied the compact GIS type ELK-14, which saves space
and offers immunity to harsh environmental conditions. Owing to its reduced footprint,
GIS is highly suitable for dense urban areas and meets the most exacting aesthetic
demands. Its inherent operational safety and maintenance efficiency is further enhanced
by the SAS 690 advanced Substation Automation System. The proven
functionality including interlocking and automatic sequences provides high-quality operator
support for control and monitoring of the entire stations. The systems are based on the
verified implementation of IEC 61850 to ensure their openness for functional and hard-
ware extensions at any time. The use of the scalable REC670 bay control unit on all three
voltage levels simplifies local control and maintenance. A fully redundant station level
ensures high availability. System integration of third party protection IEDs is efficiently
handled via a COM581 gateway for protocol conversion between IEC-103 and IEC 61850.
The Customer The Challenge
ABB’s solution
Reliable turnkey implementation of three new 220 kV
GIS substations including the entire secondary
equipment needs to be performed. The stations are
located at the Bahrain Financial Harbour, Sitra Power
Station and the town of Buquwwah. Each shall com-
prise seven switching bays in a double busbar con-
figuration. Most modern systems for central control
and monitoring as well as bay protection and control
shall be based on the new global standard IEC 61850.
Telecommunication and auxiliary systems shall allow
efficient operation and data exchange
between the substations and the
National Control Centre.
The existing communication network, with STM 1 rings formed using the integrated
SDH/PDH platform of ABB FOX 515, provides redundant communication channels to the NCC
and shall be extended to seamlessly integrate the three new stations. The same applies to the
teleprotection, where the state-of-the-art NSD 570 will again be used and can be configured
for both optical and electrical communication media.
Within the turnkey projects, ABB realized the entire value chain,
i.e. project management, design, engineering, manufacturing, testing, installation
and commissioning.
