| Abstract |
This paper brings some practical results of
research devoted to the new generation of mobile electrical
power sources, based on the VSCF technology (Variable
Speed – Constant Frequency). In this generation of mobile
electrical power sources the driving motor and generator
speed is optimally controlled in accordance with the load
power thus decreasing the fuel consumption. The output
voltage and frequency are stabilized by means of power
electronics converter. The measurements show that the real
drawback of this concept of EGS with variable speed of
engine is the engine-generator dynamics at sudden transient
from low load to high load. Dynamic behaviour of the
driving engine in the case of sudden power output increase
requires the time of few seconds to change the speed of
engine from low to higher speed. During this time, the
power required by the load is not available and diesel engine
can by high load at the low speed stop undesirably.
Electronic converter can improve the dynamic behaviour of
whole EGS system by means of inserting accumulated
energy to the DC link of AC/DC/AC converter. |
