摘要： An on-site power plant (24) has a controller (40) that selectively controls operation of prime movers (26, 28, 30). In one example, the controller (40) changes the number of operating prime movers responsive to a transient in a load (22) requirement while continuing to operate at least one of the prime movers. One example includes prioritizing the prime movers (26, 28, 30) for operation based upon the needs of a cogeneration unit (32, 34, 36) associated with the prime movers for providing a temperature control function within a facility. Another example includes controlling operation of the prime movers based upon a capacity for fueling the prime movers.

摘要： A combined heat and AC power generating system is disclosed having black start capability for the full time, simultaneous production of both electricity and heat. Heat generated within the system is captured and used for heating applications such as heating building air and tap water. The power generating system comprises an engine, generator, rectifier, variable frequency drive inverter, and inverter control electronics. The system provides improved efficiency and prolonged engine life by always operating the engine with its throttle fully open to obtain maximum efficiency and the engine is normally operated near its stall point. In this operating state the inverter control electronics adjust the power output from the inverter to control the speed of the engine. This is done by increasing the power output from the inverter when the power drawn by the load decreases. This causes the engine to operate closer to its stall point and it slows down. The power from the inverter is decreased when the power drawn by the load increases. This causes the engine to operate further from its stall point and it speeds up., The slight power changes to facilitate this operation will always be drawn from or distributed to the electric utility grid so there is no wasted power. The inverter control electronics are responsive to signals from loads such as refrigeration loads to cause the frequency of the inverter output to change to permit the refrigeration load to operate more efficiently.

摘要： This disclosure relates to minimising the losses in a power drive system. In particular it relates to detecting excess power and automatically activating and deactivating a system to redirect the excess power away from the power drive system into the supply grid. A method of controlling power for a system is disclosed, said system comprising a first controller (14), a motor (16) for driving a load, and supply means (12) for supplying power to said motor (16); said method comprising: monitoring a signal representative of power within the system; using said signal to determine if the power within the system exceeds a first threshold; and if it is determined that said first threshold has been exceeded, activating the first controller (14) to supply power from the system to an output.

摘要： A controller ( 28 ) for a doubly fed induction generator ( 12,20 ) adjusts control signals to a rotor side converter ( 24 ) and line side converter ( 22 ) to adjust rotor current when a voltage transient on a utility grid ( 10 ) occurs, so that the doubly fed induction generator can ride through the transient. The controller can also turn off the transistors of the rotor side converter ( 24 ) to reduce rotor current and/or activate a crowbar ( 42 ) to reduce the voltage of the DC link ( 26 ) connecting the converters ( 22, 24 ) when significant voltage transients occur on the grid ( 10 ). This permits continued operation of the DFIG system without disconnecting from the grid.
