[Abstract]:The ship axle belt system can make use of the reserve margin of the main engine power of the ship to improve the energy efficiency of the ship. It is of great significance for energy saving and emission reduction and reducing the operation cost of the ship. Because the doubly-fed machine is easy to operate at variable speed and constant frequency, it can realize independent active power, reactive power regulation, deep forward phase operation ability, easy to operate stably, has four quadrant operation characteristic, and the required converter capacity is small (motor slip power). With the development of power electronics and motor control technology, it is of practical significance to introduce doubly fed machine into shaft belt system. Variable speed constant frequency (VSCF) device, which controls AC excitation of doubly fed machine rotor, is the key equipment of doubly fed shaft belt system. There are more theoretical studies in China, but few engineering applications. This paper summarizes and compares different schemes of ship shafts, summarizes the development status and research trends at home and abroad, and selects the doubly fed shaft belt variable speed constant frequency device as the research object to carry out the research. Firstly, the mathematical model of doubly-fed machine is established, and the operation principle of doubly-fed machine is analyzed. The dual-PWM converter is used to provide AC excitation for doubly-fed machine, and the mathematical model of double-PWM converter is established. The simulation system of doubly-fed shaft belt is built in Simulink, and the simulation research under different working conditions is carried out to verify the correctness of mathematical model and control method. The main circuit and controller requirements of variable speed constant frequency (VSCF) device in doubly fed shaft belt system are analyzed in detail. The main circuit and controller of VSCF are designed and developed, and the DSP control software is programmed. Finally, the test system of low power doubly fed shaft belt system with variable speed constant frequency (VSCF) is built, and the running test under different working conditions is carried out. The test results show that: The variable speed constant frequency (VSCF) device can control the operation of VSCF generation and the decoupling control of active power and reactive power with doubly fed shaft. The design function is realized. The research results in this paper can be applied to marine shaft-belt power generation system, and have great value in popularization.
