In the "Isochronous" mode, the 2301E-ST controls plant/unit frequency control by maintaining turbine speed. The engine governor controls engine speed, and in some generator applications, generator load. The meaning of ISOCHRONOUS GOVERNOR is a governor that maintains the same speed in the mechanism controlled regardless of the load. One isochronous controller is attached to each generator, the inverter, and the static switch. Each of these systems has pros and cons for simplicity and operational characteristics, and when engineering a generator paralleling system, the engineer must carefully consider these characteristics so that the system provides power that is suitable for the connected loads. " This assumes the governor to be set for speed droop operation. A liquefied natural gas facility in the United States is being expanded to allow the liquefaction of natural gas and exportation of liquefied natural gas while keeping intact its existing import facilities. Isochronous Random frequency variation: ± 0. A commercial isochronous generator control system has been used for system control, monitoring, and display, and has been adapted to incorporate the energy storage inverter. The Cat® C1.
