heal.abstract	The proper control of the shaft generator's (SG) Automatic Voltage Regulator (AVR), or the AVR soft-starting method, can produce significant amounts of electric energy required for efficient ship maneuverability. AVR soft-starting method can be used to solve the transient start-up power problems in ships. The method is based on gradually increasing the output voltage of the dedicated shaft generator, but without any power harmonic pollution. The proportional increase of output voltage is achieved by properly controlling the SG's AVR. A demagnetization procedure must be completed before start-up to eliminate the risk associated with remanence flux that can spoil AVR initialization. The voltage output must start with a non-zero value to avoid voltage breakdown, and the generator root mean square (rms) terminal voltage (Vrms) can be set during the motor start-up. The method is claimed to be the least expensive among other equally useful and technologically advanced starting methods.	en
