Natural gas fuel starvation at large power plants in the U.S. and the effect of gas delivery arrangements on reliability

Power plant failures are correlated with each other

Planners use historical data to anticipate the amount of power plant capacity needed.

• They previously assumed that power plants fail independently.

• In 2018, Murphy et al. showed that this assumption was violated in most regions

• This could lead to increased risks of blackouts.

• They did not identify why there were correlated power plant failures.

NERC Training Announcement - GADS Conventional and Wind Training

by ronfluegge 4. August 2018 13:41

The NERC Generating Availability Data System Working Group (GADSWG) implements a uniform approach to reporting and measuring North American generating plant availability, performance and other related reliability data.

Conventional GADS training will include items such as how GADS data is used, events and performance, combined cycle component versus block reporting, the case for event reviews, review of cause codes, examples of poorly reported events to NERC, understanding Data Reporting Instructions (DRI) Appendix F: Equations and the data submittal process at Open Access Technology International (OATI).

Wind GADS training will include the reporting implementation timeline, entity registration, processes and reports. Additionally, the data submittal process through the NERC GADS Wind reporting application will be covered.

The GADSWG will offer training at the following location:

Week of October 15th at SERC Reliability Corporation, Charlotte, NC
Click here for Training at SERC in Charlotte, NC

Training classes conducted are:
•    An introductory session for new conventional GADS reporters on Monday
•    Conventional GADS material will be covered on Tuesday
•    Appendix F  and analytics in conventional GADS will be covered on Wednesday
•    GADS Wind material will be covered on Thursday and Friday

Training Schedule:
•    Monday | Noon – 1:00 p.m. Registration | 1:00 p.m. – 4:00. p.m. Introductory Session
•    Tuesday | 9:00 a.m. – 4:00 p.m. | Conventional GADS
•    Wednesday | 9:00 a.m. – Noon | Conventional GADS Appendix F Equations and Analytics
•    Thursday | 9:00 a.m. – 4:00 p.m. | Wind GADS
•    Friday | 9:00 a.m. – Noon | Wind GADS

Although registration is required, there is no fee for this training.  Continental breakfast and lunch will be included.

For more information or assistance, please contact NERC via email: gads@nerc.net for conventional units or gadswind@nerc.net for wind plants.

A NERC Wind GADS Solution End-to-End

by ronfluegge 27. July 2018 07:48

Versify’s NERC Wind GADS management software is integrated with the Versify Generation Outage Management Enterprise System and automates the NERC Wind GADS reporting process to insure data accuracy and consistency with reported outages.  To meet the GADS-W reporting instructions, Wind Generation Owners may require an automated tool to manage the data volumes and complexity.

The reporting requirements specified by NERC Wind GADS require detailed operational data for each turbine in a generator’s portfolio.  NERC Wind GADS reporting is much more data intensive than traditional fossil plant reporting that has been required by NERC for many years.  For example, a 200 MW wind site may have data for as many as 200 turbines that must be reported.

Versify’s NERC Wind GADS software can be configured to automatically identify turbine fault codes from various turbine manufacturers and assign them to the NERC Wind GADS system and component codes.  The module generates the required NERC GADS files based on the automated events captured along with key performance indicators.   These KPI’s provide visibility into the wind fleet, wind farm, and turbine performance and reliability.
