Abstract
A reciprocating engine system includes a turbocharger system including a mechanically driven compressor, an electrically driven compressor, and a compressor bypass valve. A control system is programmed for generating control signals for: under nominal full load operating conditions, minimizing gas flow through the compressor bypass valve and compressing gas within the electrically driven compressor to maintain a speed set point or a full load power set point of the reciprocating engine system, under off nominal full load operating conditions wherein an efficiency of the mechanically driven compressor is reduced, compressing gas within the electrically driven compressor to compensate for the reduced efficiency of the mechanically driven compressor and to maintain the speed set point or the full load power set point of the reciprocating engine system, and under partial load operating conditions, partially diverting the gas flow through the compressor bypass valve in response to the reduced load.
