Research On Wave Power Generation Control And Monitoring System

It is seriously persecuted by energy problems present worldwide,reducing emissions of greenhouse gas has already consensuses around the world.Currently,renewable clean energy is rapidly developing,as the earth is covered with the ocean,the ocean energy also contains the important position which it was excited,however technology development is not matured,most of the power generation devices are still keeping in the experimental exploration stage,it is more and more important that how to effectively reduce the dependence on fossil fuels and natural gas and how to change life which people used traditional energy habits.In addition,it is not only that for limitedly capturing the wave energy and achieving higher energy efficiency,but also had high level request that for post-processing scheme of unstable electricity and real-time monitoring technique.In this thesis,it is focused on three parts which are the key components of capture device design,hardware and software design for monitoring system and the experimental research,through these three topics would be used for design and research on the wave energy power generation monitoring scheme.This thesis has mentioned that the renewable energy utilization has new requirements during the response of the 13 th Five-year plan.As the starting point of project actual application and the objective for enhancing the equipment efficiency,under the learning of wave energy power generation absorption equipment mechanical structure,it is optimized and innovative design which been used the preliminary captured device of power generation equipment.It has been paid more attention on the research and design of the third-stage power generation system and the power post-processing system in the power plant and also studies and set up the data transmission and monitoring system.In conclusion,using these activities could be tested the rationality and feasibility of the design,this thesis main contents include:1)Pointing out the current energy crisis situation,analyzing the technical difficulties of current wave energy power generation and also researching wave energy capture mechanism,therefore in this thesis it is showed that the research contents three stages of the generator device;2)Proposing a new type of dedicated two-way power generation impeller and generator design scheme and the design of the impeller is designed from the mature wind turbine design theory and the impeller design theory of the axial flow pump,also it is measured the impeller design data is 622 mm.According to the design principle of the generator and combined with the characteristics of wave energy,it can be designed 500 W slender type,concentrated winding,less slot multi-pole and sealed underwater permanent magnet generator3)Designing the completed electrical control system as a formal set,it is researched and designed include rectification,Boost unit,lithium batteries,DC/DC unit and inverter units,and using hardware and software for programming design of system CPU;The PID control strategy of duty cycle perturbation method is used to obtain the optimal ratio of impeller speed,it is smooth and efficient used for the power from the power generation system which is post-processed,under the Matlab/Simulink environment,sea water flow rate will used the power source to input control system,finally getting a higher coefficient of energy and stability in the 210V-220 V voltage and meet the power requirements of the post-processing design.4)Using GPRS wireless communication power generation equipment to obtain electric current in the Monitoring system,voltage,power and other data,by using of double-channel data transmission and through CPU control information memory and interrupt time,also using VB design the PC software and remote device to achieve data transmission monitoring5)Building the laboratory test system,the impeller,new power generation system and control monitoring system which been obtained the experimental data,data analysis concludes that the power generation system and its control effect can meet the sea test requirements;during the equipment test in the sea,recording relevant actual test data,through the process of experimental data analysis and research,and also the actual voltage is in a reasonable range,therefore the test results show that the control system is correct,at the same time it has been created a device by using wave energy power generation monitoring system,therefore it can be a better result for further study.
