Steam turbine retrofitted governing systems are being designed with today's technology to operate a turbine in a safe and reliable manner. The design is completed with an extreme amount of effort being concentrated in the system operation and system interface areas. There are numerous control and supervisory equipment manufacturers who are capable of producing a system, which may be utilized to operate over the complete line of steam turbine applications. Many areas must be investigated prior to placing an order, installing the system, and operating the retrofitted governing equipment. This paper will aid the end user in this investigation.
