Two Single Point of Failure Case Studies, Implementation of TIL 1524 and 1275: what you need to know, and Control Hardware Field Updates

Thursday, November 12, 2020 @ 3:00pm and 3:30pm EST

Presentation Synopsis

Controls: Operational Tips through Case Studies, Lessons Learned from Implementing TILs

  • Single point of failure resolution case studies
    • Ambient Temp Thermocouple differential causes Not Ready to Start
    • Speed pick up spike trips the unit during start
  • Implementation of TIL 1524 on Gas Turbines – modified sequence (no software simulation)
  • Implementation of TIL 1275 on Gas Turbines – modified valve sequence
  • Control Hardware News: Mark VI and Mark V

1. Mark VI bad batches of semiconductors. GTC identified bad batches of specific components. The symptoms include randomly going off-line, failure to operate after a firmware download and subsequent reboot.

2. Mark VI sub-standard components on VSVO cards. Several batches of VSVO cards were released with sub-standard components.

3. Mark VI cards failure modes missed in the OEM’s TIL. GTC identified cards missed in the OEM’s Technical Information Letter about Analog to Digital Converters (ADC).

4. Mark V Critical cards released by GTC. GTC identified two critical cards in the Mark V panel that are becoming difficult to obtain, the TCPS and the PTBA. The GTC versions of these cards enable the life extension of the panel.

Key Takeaways for Users

Main Takeaway: A better understanding of the factors that determine a “Single Point of Failure” and how to identify them, and the “not-so-evident” aspects of the TILs that can only be learned after implementation.

Mark VI Takeaway: Participants will learn about previously unknown/undisclosed failure modes, how to detect if their Mark VI is potentially susceptible to it, and what their options are for avoiding future occurrences.

Mark V Takeaway: Participants will learn about two new GTC critical cards that will enable them to extend their Mark V panels lives.

About GTC Control Solutions

Founded nearly 20 years ago, GTC Control Solutions (GTC), formerly known as Gas Turbine Controls, positioned itself as the premier technology supplier of Spares, Repairs, Training, Field Services and Asset Recovery for all versions of General Electric (GE) power plant controls systems. Since then, we have expanded our support infrastructure to include several manufacturers, such as, ABB, Alstom, Bently Nevada, Fanuc, Honeywell, Ovation, Rolls Entronic, Siemens, Triconex, Westinghouse and Woodward. GTC is a pioneer in the industrial controls industry providing a vast inventory of original and re-manufactured control boards and spare parts. We are built on a foundation of unrivaled customer service and value, allowing the end user to get the most life out of their equipment, even when “end-of-life” notifications have been issued by the original equipment manufacturer (OEM). GTC Control Solutions is based out of Hawthorne, New York, with additional international service and operations in Argentina, Denmark, India, Malaysia and United Arab Emirates.

Products and Services

GTC expanded our scope to include more of the makes and models of systems you have in your plant. We have more of what you need in, ABB, Alstom, Bently Nevada, Fanuc, General Electric, Honeywell, Ovation, Rolls Entronic, Siemens, Triconex, Westinghouse and Woodward. Testing & Repair – Our Test & Certification and Repair Services, available for many of the product lines we sell, include a detailed Technical Report and Warranty Certificate, with an unmatched certification period of up to six years. Training – A variety of courses carried out by knowledgeable instructors and practicing field engineers. You have the option of predefined seminars or fully customized classes to suit your specific requirements. Field Services – Health Checks for Turbine Control Panels, Excitation & LCI, Troubleshooting & Outage Support, TIL Review & Implementation, HMI or <I> Replacement-in-Kind, EEPROM Backup Service and NERC Compliance. Asset Recovery – If your original system doesn’t have the current features you require, GTC can upgrade your technology to a more recent legacy system for a fraction of the cost of a new system from the OEM. However, if you decide upon an OEM upgrade, GTC can help you defray the cost by acquiring your pull-out system and spares.
