Description: In the first generation of the vehicle two diesel engines will provide energy to a
generator transforming it to 700V on a DC bus. The DC bus provides enough
energy for both propulsion and the auxiliary equipment. The now existing
prototypes are, to a large extent, equipped with hydraulic systems for energy
conversion. It is desirable to replace the hydraulic system with an electrical one.
As a part of the development this master thesis will evaluate a prototype of an
inverter for the cooling fan motor. Platform: |

Description: The power system of an all-electric navy ship has an integrated network, where the propulsion load, the distribution loads, sensor and other emergency loads and pulse loads (rail guns, aircraft launchers etc.) – all are part of the same electrical network. Among the loads, the effects of pulsed loads are most detrimental for the power quality of ship power distribution system as the pulsed loads require a very high amount of power for a very short period of time . In order to improve the survivability of a navy ship in battle condition, DSTATCOM or Distribution Static Compensator can be used, which reduces the impact of pulsed loads on the bus voltage and thus keeps the bus voltage at desired level.

Description: Abstract:
Voltage and reactive power control is a fundamental issue in all-electric shipboard power systems (SPS). However, coordination between generation and propulsion management to match reactive power is poor in current SPS designs. This paper presents a new model predictive control based dynamic Volt/Var control scheme to control the voltage in the system. This method uses a dynamic model of the sources and loads and finds the optimal reactive control inputs to the system to minimize the voltage deviations in the future. Since this method uses prediction of the reactive demand of pulsed loads, it is able to achieve a smooth voltage profile in the SPS in presence of pulsed power loads. This method is also able to control voltage of the system during propulsion motor startup. The controller is tested in presence of high power pulsed loads in the system. Platform: |

Description: 把船舶推进轴系描述为螺旋桨、2号中间轴、推力轴承和艇体四部分。对推进轴系—艇体耦合系统的纵向振动功率流和振动能量进行数值计算，研究分析纵向振动功率流传递路径中的各种子系统中2号轴参数、推力轴承参数、艇体参数、螺旋桨质量对功率流传递特性的影响规律。(The ship propulsion shafts are described as 2 parts: propeller, intermediate shaft No. four, thrust bearing and hull body. The longitudinal vibration power flow and vibration energy of the propulsion shafting - Hull coupling system are numerically calculated. The influence of the 2 axis parameters, the thrust bearing parameters, the hull parameters and the quality of the propeller on the transmission and recurrence of the power transmission in the transmission path of the longitudinal vibration power flow is studied and analyzed.)
