Peaking Power, Chapter Twenty: F-Technology and Beyond

Published on December 26, 2012 By dlucier

General Electric began offering the MS7001FA around the turn of the 21st Century.  The most obvious distinguishing feature of the 7F technology was the “cold-end-drive” design.  The generator is connected to the compressor end of the turbine rotor, a departure from GE design concept for over 50 years.  Also, unlike the MS7001EA design, the 7F [...]

Peaking Power, Chapter Sixteen: Computerized Control Systems

Published on May 21, 2012 By dlucier

In the early 1980s, General Electric introduced the Integrated Temperature System (ITS) version as an option for Speedtronic™ Mark II.  It was GE’s inaugural venture into the use of computers to control gas turbines, abandoning some of the standard integrated circuitry of Mark II from the previous decade.  ITS dealt primarily with exhaust temperature signal [...]

Peaking Power, Chapter Thirteen: Speedtronic™ Control and Protection Systems
