Black Start, Chapter Thirteen: Speedtronic™ Control and Protection Systems

Published on January 30, 2012 By dlucier

  General Electric unveiled its first electronic control and protection system in 1970.  It was called Speedtronic™.   Other manufacturers similarly introduced electrical and electronic controls on gas turbines at the about same time.  The name for GE’s system came from the combination of Speed control by elecTronic.  I’ve had difficulty confirming who came up with [...]

Black Start, Chapter Twelve: The Mighty MS5002 Gas Turbine

Published on November 25, 2011 By dlucier

  The two-shaft gas turbine was first introduced in the 1950s.  They showed some popularity in gas pipelines and chemical process plants in the 1960s, where variable-speed load compressors (made by manufacturers other than GE) were required.  These load compressors were designed to operate at speeds different than the gas turbine’s own axial-flow compressor.   [...]

Black Start, Chapter Eleven: The Long-awaited Frame 7

Published on October 17, 2011 By dlucier

  In 1971, General Electric finally offered a power plant of the size that most electric utilities wanted 6 years earlier after the Northeast Blackout of 1965.  It was called the model series MS7001 package power plant.   Also known as the Frame 7, it was rated approximately 40 megawatts, making it nearly three times [...]

Black Start, Chapter 8: Compressor Drives for the Industrial and Gas Pipeline Industry

Published on July 2, 2011 By dlucier

  In the 1950s, General Electric designed, constructed and installed hundreds of 2-shaft gas turbines.  The units had two, mechanically-independent turbine stages.  The high-pressure (HP) turbine powered the turbine’s own 15-stage, axial-flow compressor.  The low-pressure (LP) turbine drove another manufacturer’s load compressor (Cooper-Bessemer, Nouvo Pignone, Dresser).  These turbines were used primarily in the gas pipeline [...]

Black Start, Chapter 7: The Fuel Regulator

Published on May 15, 2011 By dlucier

The first control system used on GE gas turbines in the late 1940s was manufactured by Young & Franklin (Y&F) of Liverpool, NY.  It was called the Fuel Regulator, although fuel does not actually flow through the device.  It is a mechanical-hydraulic control (MHC) device that has an electric governor and pneumatic temperature control element.  [...]
