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 - CDC7T

The 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 Simulation

Development 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 Networks

The 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 Cast

Robert 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.

The Growth of Siemens PTI US in Medium Voltage Distribution Network Solutions in the Past Year has been Remarkable, Thanks to PSS®SINCAL

Siemens PTI US, and our PSS®E product suite, are widely recognized as a world leader in steady-state and dynamic studies for power transmission systems. We are also well equipped with the consulting expertise and software tools required to perform FACTS and HVDC studies.
 
The success of Siemens PTI US after our acquisition by Siemens in 2005 can’t be discussed completely without mentioning our work in medium voltage distribution 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 year. In addition to transmission related projects, consultants at the Houston, Texas, regional office have been actively involved in these distribution planning studies.

NERC Reliability Standards — Mandatory Compliance

As 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.
