Abstract

Described is a power generation system, comprising a variable speed generator and an engine for driving the generator to supply AC electric power output. The output is monitored so as to detect different types of transient conditions, for example, the outputted current is estimated to identify the first type of transient condition, the outputted power factors are estimated to identify the second type of transient condition, and system control is conducted according to the types of conditions. In one form, the system is used for providing vehicle electric power for vehicles, such as electric buses and ships, and in other forms, the system can not use a remote building of a public electricity supply network to provide electric power and cannot supply standby power under a power grid failure situation.
