How to Start a Frequency Converter for a Gas Turbine Generator?
A static frequency converter serves to bring a large gas turbine generator up to near its operating speed as it is being brought online (put into service), at which point the turbine takes over power generation and maintains its speed. You must take care to use a static frequency converter only to the point where it is no longer needed, then shut it down.
1. Open the generator circuit breaker.
2. Connect the static frequency converter to the generator bus duct.
3. Switch the static frequency converter to "on". Turn the static excitation switch to "on".
4. Raise the speed of the turbine to approximately 70 percent of synchronous speed.
5. Switch the static frequency converter and static excitation switches to "off".
