摘要： An electric power generation system having two main sources of ac power comprises a first and a second main power conversion and distribution unit (MPCDU1, MPCDU2), each electrically coupled to one of the sources of ac power. The MPCDUs controllably supply ac electric power to an associated main distribution bus and additionally convert that power to a second type of power. This second type of power is supplied to an associated secondary distribution bus and to a converted power output. The system also includes an auxiliary source of ac power and an auxiliary power conversion and distribution unit (APCDU) which is electrically coupled to the auxiliary source. The APCDU controllably supplies ac electric power to a ground service distribution bus and additionally converts that power to a second type of power which is then supplied to an associated secondary distribution bus and to a converted power output. Additionally, the MPCDUs and the APCDU each controllably supply ac electric power to, and demand power from, an ac tie bus. The system additionally comprises a central power conversion and distribution unit (CPCDU) which is electrically coupled to the converted power output of each MPCDU, and to the converted power output of the APCDU. The CPCDU selectively converts the second type of power from each MPCDU and the APCDU to an emergency type of power. This emergency power is controllably supplied to an emergency distribution bus.
