Parallel operation of Brayton cycle alternators. I. Formulation of mathematical model

The development of dynamic power system models for space applications which use multiple generators operating in parallel is presented. The system will include a mathematical model of the Brayton cycle alternator with voltage and active power control in both single operation and a multiple generator in parallel operation. Multiple generators operating in parallel at the same bus and connected to the system network each have a single parasitic load speed control. Coordination of the control actions of a single alternator and a group of alternators sharing the common system load demand is formulated, and mathematical models and control are developed. The more general case of complex system control and coordination of control actions with the parasitic load controllers is presented, and the mathematical model is formulated. The subject of the parallel operation of Brayton cycle alternators is treated from the point of view of system formulation and mathematical model definition
