Abstract: The original cause of starting up of level F gas turbine generation unit with frequency conversion was introduced. Taking the S109FA unit as example, the different points between the typical connection of generator PT and the conventional connection were analyzed. The improvement scheme for PT typical connection was put forward, which is helpful for ensuring safe operation of the unit.
