I March-April 2008 Issue
IN THIS ISSUE
22 Replace Existing Normal?
Whenever I make fundamental changes to a word processor document – i.e., changes that
affect the basic structure; not just content changes – and get ready to quit the appplication, I
sometimes get a message that says, “Do you want to replace the existing Normal?”
26 Mining the Corporate Data Domain Safely and Securely Across
the Enterprise
In these times of increasingly stringent regulatory compliance reporting by utilities, the
most rigorous of which being Sarbanes-Oxley for publicly-held corporations like Entergy,
the transmission and distribution (T&D) departments requires an auditable and reliable
source of historical data with no gaps.
34 The 2008 automation/it leadership series
In this issue, we are privileged to be able to share the thoughts and insights of two key
executives from ABB’s North American Power Products and Power Systems divisions.
44 Key issues for Implementing a Prudent Control System Cyber
Security Program
The goals of a prudent control cyber security program should be to help make the
utility/entity more secure, maintain and when possible, improve system reliability and
availability, and meet regulatory requirements.
50 Data Refresh: Breathing New Life into a GIS Database
Geographic Information Systems (GIS) are the latest evolution of spatial technology, with
their origins in simpler systems such as Computer Aided Design (CAD) and Automated
Mapping/Facility Management (AM/FM) systems.
53 Making Substations More Intelligent by Design PART TWO: Bringing It All
Together at a Northeast Utility
Building on part 1 of this article in the previous issue, this second installment illustrates
the issues and impacts of implementing substation integration in harmony with the
utility’s organization and operations using a standards-based approach.
64 Getting a charge out of service optimization
For decades, electric utilities have invested millions of dollars in computer technology
and human resources to reliably forecast future demand.
68 Providing High Speed Relay Fault Protection between Substations
Serial communications has been the mainstay for communication systems for more than
a decade using RS 3 and RS485 as the physical layer.
74 An Integrated Utility Network
The business case for business service management (BSM) at Ontario’s Independent
Electricity System Operator, commonly referred to as IESO, started out as a proposal for
solving a traditional IT management problem.
79 Prevention of Oil-Filled Transformer Explosions
Power transformers are one of the most dangerous electrical equipments because of the
large quantity of oil they contain which is in direct contact with high voltage elements.
