The isochronous Generator inclu-des a powerful graphical editor to specify what isochronous ‘blocks’ should be sent for up to 64 chan-nels simultaneously. It depends on the governor manufacturer, and if the governor is capable of both then there must be a method for switching between the two (since both governors modes cannot be active at the same time in the same governor). Isochronous Load Sharing with a Fixed Bias Speed – permits a GTG connected to an external grid to maintain speed while the GTG output MW varies. An asynchronous Generator is a maker in which the parts are largely autonomous. Nah dari governor valve inilah jadi ada 2 jenis operasi turbin, yaitu : 1.
