your instalation contains Examples folder. Go to the direction .......\PS cad\Examples\DieselEngine. This study contains nice example with diesel engine with induction generator. You can easy change induction generator to synchronous machine with exciter. Diesel engine (IC engine block) uses speed governor (Woodward gov. with Lead-Lag regulator), which is important for islanded grid. In islanded grid, you can set speed reference for diesel to 1 (for nominal frekquency) and set exciter reference voltage to nominal value 1 etc. In islanded grid diesel generator will feed loads with required P and Q and regulate frequency and voltage at nominal values. If you connect this model with this setting to the power grid, real power of generator will be 0. When you change speed refference from nominal (1), real power will increase.
