LIFING AND PERFORMANCE OPTIMIZATION LIMIT MANAGEMENT FOR TURBINE ENGINE

摘要

A control for a multi-shaft turbine engine system using electrical machines seeks optimal system performance while accommodating hard and soft component limits. To accommodate the component limits, the control may generate a number of possible operating point options reflecting potential trade-offs in performance, lifing, efficiency, or other objectives.

主权项

1. A control for a turbine engine system comprising a plurality of components including a multi-shaft turbine engine and one or more electrical machines coupled to the shafts of the turbine engine, the control comprising:
a constraint analyzer to determine applicable component limits based on current operating conditions of the turbine engine system, wherein each of the component limits defines an operating region in which, if the component limit is exceeded, the life or safety of the component may be compromised; and a limit management optimizer to generate a desired operating point and one or more possible operating points for the system based on the current operating conditions, the applicable component limits, and an optimization objective, wherein the one or more possible operating points each represents a functional trade-off involving a reduction in a component function to maintain the component limits, an objective trade-off involving a modification of the optimization objective to maintain the component limits, or a modification of one or more of the component limits.
