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.
In 1997, Hydro-Québec wanted to control dynamic
voltage surges on its 735KV transport network, and
turned to Cooper Power Systems for a solution. Cooper
Power Systems had already participated in numerous
major Hydro-Québec projects and proven to be a highly
valuable resource.

In response to Hydro-Québec's requirement, the
custom software and consulting group designed an
automatic shunt reactor control system and included its
Substation Modernization PlatformTM (SMP) as part of
the solution. The SMP Gateway performs all real-time
data acquisition and implements a sophisticated signalprocessing algorithm to control the shunt reactors in
less than 25 milliseconds.
All communications protocols used for the project are
proprietary and were specifically defined to meet the
stringent requirements imposed by the customer. One
of these protocols is used to acquire real-time data
from the field over a redundant high-speed serial link
(10 Mbps). A second is used to remotely send and
receive parameters, real-time data, application code
and PLC functions from a maintenance console. A third
is used to communicate with a master station for the
purpose of dynamically changing the system's
behavior.
