This paper presents a position sensorless control strategy of stand-alone doubly fed induction machine (DFIM) used for ship shaft generation systems. Direct voltage control method is used to generate constant frequency and voltage with variable load and main engine speed. The strategy does not need any signal from speed, so the position encoder or estimators are unnecessary. The space vector pulse width modulation (SVPWM) technique is used to reduce the rotor current harmonics and the modification of the reference stator vector angle is applied to achieving the reference stator voltage quickly and successfully. Simulation results are given to illustrate the efficacy of the proposed method.U

“…The system can also reduce the maintenance, engine noise and heat source [1].It is the effective means of saving operation cost and improving the operating conditions of room management that attract the attention of the shipping industry and shipbuilding industry.The fixed propeller pitch and variable speed constant frequency are the focus of attention among the ship shaft power generation system.The brushless doubly-fed generator for ship shaft power generation has many advantages compared with the traditional shaft generator system.It is a novel generator applied to the fixed propeller pitch ship and developed [2]. This generator adopted a special rotor structure and can reduce the failure rate and improve the maintenance by canceling the slip ring.Due to the converter in the rotor circuit, only deals with the slip power, therefore the converter in the shaft doubly-fed generator system is small in size,cheap.It is an advisable choice for ship shaft power generation system.This paper studies the ship shaft power generation system based on BDFG control methods and completes the design of the system hardware environment on this control method.The experimental result is presented to demonstrate performance of the control strategy by analyzing the ship shaft power generation system operating mode, BDFG based on mathematical modeling and the stator-fluxorientated vector control methods.…”

Ship shaft power generation technology is a kind of effective energy saving way,which can reduce the operating cost in the vessel traffic.Not only bring economic benefits, but also will improve the comprehensive economic indicators of the shipping industry. Compared to the traditional ship shaft power generation system, the shaft power generation systems based on brushless doubly-fed generator (BDFG) has the advantages of smaller capacity of the inverter, lower capital operational costs and higher reliability.The paper analyses the ship operating mode, and presents the control strategy of BDFG.The system hardware environment is established based on the control strategy.The physical verification is developed.The results show that the control strategy has good dynamic performance when the speed and power are change.

“…The ship shaft power generation system is driven by the main engine of ship, which can make full use of the 10% ~ 15% power reserve margin of the main engine, and make it running in high efficiency and low energy consumption, reducing the consumption of lightweight fuel oil, the noise and heat source as well as the maintenance [1]. Since the SSPGS has energy-saving, economic and other prominent features, it is widely concerned in today's and future ship traffic.…”

The Ship Shaft Power Generation System (SSPGS) is widely used in large and medium-sized container ship, and the SSPGS based on brushless doubly-fed generator (BDFG) has the advantages of smaller capacity of the inverter, lower capital operational costs and higher reliability. The proposed vector control method is developed on the power-winding stator flux frame and can be used to control the power winding voltage amplitude and frequency on the standalone mode. The generator model and the control system are developed in Matlab/Simulink. The results show that the control strategy has good dynamic performance when the ship speed and load are changed.
