A multi-injector combustion system in which a brake resistor is utilized to provide a minimum load for the combustor system during idle or low power operation of the permanent magnet turbogenerator/motor and also to absorb power during transients to prevent flame out of the combustor. In addition, during single injector operation, a relighting method and system are provided to relight the combustor and prevent the necessity of a complete shutdown of the system. The method and system includes switching between the multiple injectors to find the most stable injector in single injector operation.
