Microturbine engine system

A microturbine engine system operable to provide electrical power to a load, the microturbine engine system comprising:

• a compressor operable to produce a flow of compressed air;
• a fuel delivery system operable to deliver a flow of fuel;
• a recuperator in fluid communication with the compressor to receive the flow of compressed air, the flow of compressed air being preheated within the recuperator to produce a flow of preheated compressed air;
• a combustor receiving the flow of preheated compressed air and the flow of fuel, the combustor combusting the flow of compressed air and the flow of fuel to produce a flow of products of combustion;
• a turbine driven by the flow of products of combustion from the combustor;
• a synchronous generator coupled to the turbine, the synchronous generator driven by the turbine at a speed, the synchronous generator outputting an electrical power having a frequency;
• an energy management system including a variable electric load, the variable electric load absorbing at least a portion of the electrical power, the remainder of the electrical power being delivered to the load;
• and
• a control system operable to vary the flow of fuel and the variable electric load to maintain the portion of the electrical power absorbed by the variable electric load and the frequency of the electrical power within predetermined ranges.
