Novel hybrid load-adaptive variable-speed generating system

L.M. Grzesiak , Włodzimierz Koczara , M. Ponte


Light loading of generator sets has long been the cause of accelerated aging and premature engine failure. This problem is exacerbated by impact and nonlinear loads because generator sets are oversized to cope with this condition whilst maintaining the voltage within the specified limits. A new hybrid engine-friendly load-adaptive variable speed generating system has been developed which decouples the engine from the load by means of a decoupling converter. The engine load torque can be precisely controlled independently of the load so that optimal engine operation is achieved for a wide range of load power demands. Test results show outstanding performance under the worst load conditions, superior to that of comparable systems
