| Energy and environment problem has always been a topic of debate at home and abroad recent years, while the energy structure of mainly fossil energy in the future for a long time will be the dominant, but clean and renewable energy development and utilization is of more and more important, new energy, such as wind and solar energy power, is in the ascendant, at the same time ocean power generation has been more and more attention. The project of this study relying on is integrated micro grid system research based on the offshore wind, waves and currents power supplying.Energy management and control system is the main research content of distributed micro grid system. After establishing the topological structure of the distributed power supply, energy management and control system will eliminate uncertainty on the space step by step. On the base of keeping its power supply and equipment operation safe and stable, the system will allocate the power supply output reasonable, maximizing energy source used at the same time satisfying electricity quantity and quality requirements of the loads.Monitoring system is the front of the energy management, this paper first introduces the basic structure of the grid and off-grid system, according to the off-grid system structure using in this project, the paper design the integrated power supply system monitoring system, energy management strategy and energy management system of the system structure. The researches study the inverter AC side load control technology in Matlab/SIMULINK with space vector pulse width modulation (SVPMW), and designed the energy management system in the LabVIEW, including data acquisition, monitoring, power quality analysis, energy management, operational control and database system. The article finally introduces the project background of the whole system, system software and hardware design and configuration. The experiments have proved the rationality of the system designing. |
