Retrofitting utility power plant motors for adjustable speed: Field test program
- Bechtel Corp., San Francisco, CA (USA)
EPRI recognized there was a need for converting large power plant induction motors to adjustable speed for fuel conservation. When this project started, only the synchronous motor ASD was available which required a new synchronous motor to replace the existing squirrel cage motor. The retrofitting of large power plant induction motors offered an opportunity to develop and refine a technology for large induction motor ASDs. Prior to 1984 no high horsepower induction motor ASDs were installed on utility or industrial fans or pumps, but there were 57 LCI synchronous motor systems. By mid-1986 the market evolved such that more induction motor ASDs were being installed in the US than synchronous motor ASDs. The major US induction motor ASD suppliers now offer water cooling which greatly simplifies the cooling of large thyristors in power plant environments. Included in the report is a copy of a sample ASD specification developed during the field test program. The other major output of this study, ASCON II, and IBM PC compatible computer program for technical and economic applications of ASDs to power plants, has been improved as a result of these field tests and will be made available from the Electric Power Software Center.
