The Solution
The Challenge
China National Offshore Oil Corporation (CNOOC) and
Shell Petrochemicals Company Limited (CSPC) are
building and operating a $4.3 billion USD
petrochemicals complex in Daya Bay, Huizhou
Municipality, Guangdong Province, China. It is the
largest capital investment for a Sino-foreign joint
venture project to date in the People's Republic of
China.
The Plant will be an integrated chemical complex
including steam and electricity generation, storage and
handling, shipping facilities, as well as effluent treatment
and environmental protection facilities. Many of the
production facilities are world scale, and all are
designed to international standards.
The design and construction of the power transmission
and distribution system for the plant was awarded to
Siemens Pte Ltd, the representative company of
Siemens AG in Singapore. Siemens AG (NYSE:SI),
headquartered in Munich, is a leading global electronics
and engineering company. It employs some 430,000
people in over 193 countries, and reported worldwide
sales of more than $75 billion in fiscal year 2004
(10/01/03 – 09/30/04).
To ensure continuous fail-safe operation of the power
production and distribution system, Siemens Pte
required a field-proven solution capable of integrating
the various IEDs and protection relays.

To provide fail-safe operation, Cooper Power Systems
specified a redundant architecture of SMP Gateways.
The SMP gateways are used to integrate the devices in
the substations, perform protocol translation and make
the data available to the control centers.
The Soft PLC option is used to implement sophisticated
power management functions, including the capability
to switch to auxiliary power generators in an orderly
manner in case of external power failure.
The SMP Gateways are configured for hot standby, and
switchover occurs within seconds in case of failure. To
ensure continuous data access, each SMP Gateway is
connected to the control center using dual Ethernet
connections through a fully redundant network.
By using the advanced capabilities of SMP Gateways,
Siemens Pte was able to deliver a sophisticated failsafe control and data acquisition system well within the
allocated project schedule.
