Abstract
: In this research, reactive power compensation in the ship is considered as an auxiliary factor for improving generator conditions and improving the ship efficiency in terms of fuel consumption and emissions. To accomplish this purpose, a simplified electrical network is modeled for an all-electric military marine vessel, including propulsion load, distribution loads, sensors, emergency loads and pulse loads (rail guns, aircraft launchers, etc.) Among these loads, pulsed loads have a more damaging effect on the voltage profile of power quality in the ship distribution system. Such loads often require high energy over a short period of time, which mainly causes problems in system power quality and in some cases leads to the destruction of the entire electrical system.
In the following, the compensation effect of static capacitors is investigated on voltage profile improvement of a navy ship during a pulse load. The obtained result show that using their kind of compensating has a great impact on decreasing voltage sag and, on the other hand, the speed and torque curves of the propulsion motors will be more stable. All simulation is done in Matlab/Simulink environment and for various situation (different pulse load and static capacitors). Suggested method is robust and improve the parameters of power quality in all proposed scenarios.
