Honeywell is currently working on several projects utilizing high-reactance permanent magnet machines (HRPMM) to develop advanced, high-performance power generation systems (HPPGS). These power generation systems (PGS), offer greatly increased safety and reduced operating costs compared to previous hardware. The approach utilizes an HRPMM that presents reduced short-circuit currents with simplified power topology and specifically developed control algorithms. These architectures offer inherent fail-safe features in that the maximum possible short-circuit current is not significantly higher than the normal operating current. Control approaches are discussed. Methodologies for system optimization to achieve top performance and robust operation are included. These power generators support implementation of on-shaft integration with the plant.
