The Solution
The Challenge
Created in 1944 by the Québec government, its only
shareholder, Hydro-Québec supplies electricity to nearly
4 million customers across the province of Québec. The
company also does business with dozens of power
companies in northeastern North America, and
participates in energy-related infrastructure projects on
several continents.
With assets of over $66 billion, annual sales of $12.7
billion and a work force of 19,297 people, HydroQuébec ranks among the leaders of the North
American energy industry.
No longer able to purchase new units or find
replacement parts for its distributed substation
automation system, Hydro-Québec needed to upgrade
a large number of aging RTUs. Unwilling to completely
replace their existing equipment base, Hydro-Québec
turned to Cooper Power Systems, with which it had a
longstanding business relationship, to provide an
alternative solution.
In large substations, Hydro-Québec uses a
sophisticated distributed automation system where
each RTU is based on MULTIBUS hardware running an
INTEL iRMX application. Up to 40 RTUs can be
connected to a common communications processor
using the INA-960 protocol. While originally quite
innovative, the system had become obsolete by the
lack of replacement parts and the evolution of
technology.
Instead of completely replacing the existing hardware,
Cooper Power Systems proposed an RTU
modernization solution that preserved the existing I/O
modules and cabling while providing a source of
compatible devices for new projects.
The solution is based on the SMP Gateway. To
upgrade existing RTUs, the development group
designed a custom SMP I/O module that replaces the
current processor modules while preserving the existing
I/O modules and cabling.
For new projects, Cooper Power Systems proposed a
replacement RTU based on an SMP and PAC (Parallel
Acquisition and Control) module manufactured by
Gentec, a Cooper Power Systems partner. The SMP
Gateway provides implements all the communications
and automation functions for this advanced RTU.
Finally, the original communications processor is
replaced by an SMP Gateway.
The main advantage of this modernization solution is to
provide a step by step approach where old and new
equipment coexist, thus reducing cost and total system
downtime.
