Welcome to the latest eNewsletter from
Siemens PTI US  As the incoming General Manager, it is my pleasure to announce
a leadership change at Siemens PTI US. Since joining Siemens in 2005,
Siemens PTI has enjoyed much growth and success under the seasoned
leadership of Mike Edmonds. Those skills did not go unnoticed, as Mike now
transitions to Vice-President of Siemens Energy Management and Automation,
headquartered in Minnesota.  While I take on my new role, at Siemens PTI it is business as
usual. The challenges facing the energy sector in the current economic
climate challenges from NERC compliance, to outage issues and asset
upgrades, just to name a few offer Siemens PTI tremendously exciting
opportunities for continued growth in our areas of expertise network
consulting, software technology and T&D training. We have responded
and continue to respond to these challenges with dramatic improvements in
our products and services that benefit you, our customer. 
The Siemens PTI team is committed to meet your needs by keeping the
PSS® suite up-to-date with leading-edge advances in power system simulation
technology. The PSS® suite continues to evolve as we consistently increase
the capabilities and efficiencies of all the products in the portfolio.
Version 32 of our flagship PSS®E product represents the next generation
of PSS®E technology with a completely integrated graphical user environment
coupled with a powerful database engine. Due to be released in March
2009, Version 32 will include some major features including N-1-1 contingency
analysis for North American Electrical Reliability Corporation
(NERC) requirements, substation reliability analysis, PSS® DB database,
flexible short-circuit calculations, revised and updated documentation,
as well as backward compatibility with Version 30 and later versions.
Beyond these new features, PSS®E Version 32 will also provide updated
Graphical Model Builder (GMB) and small signal Eigenvalue and Modal
Analysis (NEVA) modules. Furthermore, we have significantly enhanced
our Model on Demand (MOD®) software product, which coordinates PSS®E
cases across an enterprise and may be used as an aggregator of regional
cases among member companies. MOD® offers model coordination in a time-based
“project oriented” model.
 In network consulting, 2008 was a significant year as we
brought our consultants closer to our customers with the opening of two
new offices. Our presence in the US grew with the opening of regional
offices in San Jose (California) and Minnetonka (Minnesota), as well as
with the expansion of offices in Schenectady (New York), Houston (Texas),
and Denver (Colorado). Network consulting also launched a new practice in
Energy Market Business Solutions, which has extended Siemens PTI’s unique
expertise to assess both the technical feasibility and the financial
viability of projects within a competitive market. 
In our education department, our Siemens Power Academy TD - USA,
2009 Siemens PTI Education and Training Catalog is now presented
in an entirely new design and format - we hope you like it! Our offerings
are now segmented by discipline, including power distribution engineering,
power systems engineering, power system software engineering, power
transmission engineering, and equipment-based training. We are now able
to provide curriculum programs which will guide students in building
a progressive learning plan toward an advance certificate program; offering
both the value of the course content as well as the recognition of achievement
with Siemens Power Academy and Siemens PTI.
 As demonstrated above, we are moving forward to address your
needs. Even greater activity is planned over the coming year in all three
of our areas of expertise network consulting, software technology and
T&D training as we continually strive to support your challenges and
lead our industry. Your continuous loyalty and support drives the
continued improvement of our products and services.  Inside this edition you will find, we hope, many interesting
articles for your reading pleasure. If you have any questions or
want further information, please do not hesitate to contact the author. If
you have any suggestions for articles, we would welcome those as
well.

A New Generic PSS®E HVDC Dynamic Simulation
Model - CDC7TThe PSS®E CDC7T model simulates a pole of
the 2-terminal HVDC transmission. There are significant
differences between this model and generic HVDC models, such
as CDC4T or CDC6T, available in the PSS®E library. |

 |

Generic Wind Models for PSS®E Stability
SimulationDevelopment of dynamic stability models in
PSS®E to simulate wind farms as elements of power systems
started with vendor-specific models. So far about 25
vendor-specific models have been developed. 
Many of these models have been used successfully for years
to study dynamic response of the systems with interconnected
wind farms. However, since these models contain proprietary
information, use of most of these models requires manufacturer’s
authorization, which in turn makes the process of incorporating
vendor-specific models into dynamic setups of utilities
and power pools difficult. In view of this, the idea of
publicly-available generic wind models that can be parametrically
adjusted to any practical implementation was well received
by the community of transmission planners. |

An Efficient Method for Planning Low Voltage
Secondary Distribution NetworksThe optimal selection of
distribution transformer size and low-voltage (LV) network
conductors for a given network configuration poses various
challenges to distribution utilities. This article proposes an
efficient planning methodology to select an optimal
combination of transformer size and the LV network conductor
that would minimize the Life of Asset (LOA) costs while taking
into account the voltage drop and the transformer loading
constraints for a period of 30 years including load
growth. |

"Understanding Financial Transmission Rights”
Web CastRobert de Mello recently presented "Understanding
Financial Transmission Rights" to the largest turnout of any
web cast offered by EnergyCentral. Using a very simple system
to illustrate the energy settlement of a load (the consumer)
and generation (the supplier), Bob gave the participants an
intuitive sense of the motivation behind financial
transmission rights without the complications that are found
in real power systems. The hour long web cast included a 15
minute question and answer segment that indicated people were
itching for more. At the end of the web cast, Bob signed off
with 22 additional questions requiring his expertise; he
followed up via email. |

studies. Thanks to PSS®SINCAL, we have grown enormously in
this area, domestically as well as internationally. For
distribution and industrial clients, the addition of
PSS®SINCAL modeling and simulation capabilities has enabled us
to expand our services offered from the Houston, Texas
regional office.  The purpose of this article is to bring to light
some accomplishments of Siemens PTI US in the field of medium
voltage distribution network planning studies in the past

NERC Reliability Standards Mandatory
ComplianceAs you seek to do more with less in the way of
financial and people resources, you no doubt are awakened
during the night with nagging issues of system reliability.
You do the maximum to “serve and protect,” however it’s not
painful enough that you may experience system repercussions if
problems are encountered; NERC has been given the teeth to
levy financial sanctions in the event that you haven’t been
appropriately diligent. You can increase your intake of
sleeping pills or, more positively, seek technical help from
folks who are acquainted with your pain and who can provide
calming technical relief to put your mind at ease. |
