Research On Collector System Of Marine Renewable Energy Farm

Due to the pressure of energy conservation, environmental protection and conventional energy consumption, China is implementing the strategy of developing new energy, ocean energy as an important renewable energy, the development and use will inevitably become a hot research and cutting-edge technology in the energy sector.Wave energy and tidal energy is the greatest potential forms of energy in all kinds of marine energy. In the United Kingdom, Spain, Portugal, Denmark and other countries, wave energy, tidal energy generation devices have a lot of real sea state power, and some countries have built test fields of ocean energy power generation, marine energy generation has entered the pre-commercialization stage. China is rich in coastal ocean energy resources in economically developed coastal areas, electricity consumption is high, so we need to accelerate the application of ocean energy power generation technology and construct ocean energy power plants.At present, China has not yet ocean energy power plant, in this paper, ocean energy farm collector system for the study, focusing on ocean energy power plant generators collector topology analysis and appraisal, analysis and appraisal of the transmission system topology, propose different scenarios design and improve the performance of the power system operation method to apply different solutions and grid systems.Firstly, the trend can be analyzed, the characteristics of wave energy and wind power were compared with pointed intermittent strong ocean energy generation and contribute to instability characteristics, generators subject to constant frequency output power electronics technology and the constant pressure to network; of the specific characteristics of wave power device research, we designed a new type of oscillating water column wave energy device, the output characteristics of the device through the analysis shows that the device can not only improve the power output characteristics, smooth power output, but also improves the power generation efficiency.Secondly, an overview of the different types of generators collector topology, analyzes the advantages and disadvantages of various types of layout, and proposed a new set of electrical topology and layout done with other economic and reliability of comparative analysis, was the reasonableness and advantages of this kind exists layout. Further, both for a wave energy can flow also includes farm, the two intervals are given wiring. Eight transmission system proposed topology according to the case of three different power scale, relatively economical packet cost and power consumption of the structure, the application of different studies collector topology.This article also gives10/35kV shore-based and network systems, including the main terminal forms a substation equipment, etc. Finally, give the use of marine energy generation energy storage device to improve system performance electric field method.Papers for the establishment of marine energy farms collecting economic evaluation methods and system reliability evaluation method provides a favorable comprehensive evaluation system support; provide the basis for the construction of real sea conditions ocean energy power plant construction.
