光伏逆变器原理英文翻译

【专家解说】：离网式光伏发电系统与并网式光伏发电系统的工作原理十分相似，唯一不同的是离网系统输出的电力被直接消耗使用而不传送到公共电网中太阳能发电分光热发电和光伏发电.不论产销量.发展速度和发展前景.光热发电都赶不上光伏发电.可能因光伏发电普及较广而接触光热发电较少.通常民间所说的太阳能发电往往指的就是太阳能光伏发电.简称光电.光伏发电是根据光生伏打效应原理.利用太阳电池将太阳光能直接转化为电能.不论是独立使用还是并网发电.光伏发电系统主要由太阳电池板(组件).控制器和逆变器三大部分组成.它们主要由电子元器件构成.不涉及机械部件.所以.光伏发电设备极为精炼.可靠稳定寿命长.安装维护简便.理论上讲.光伏发电技术可以用于任何需要电源的场合.上至航天器.下至家用电源.大到兆瓦级电站.小到玩具.光伏电源可以无处不在.目前.光伏发电产品主要用于三大方面:一是为无电场合提供电源.主要为广大无电地区居民生活生产提供电力.还有微波中继电源等.另外.还包括一些移动电源和备用电源,二是太阳能日用电子产品.如各类太阳能充电器.太阳能路灯和太阳能草地厂各种灯具等,三是并网发电.这在发达国家己经大面积推广实施.我国并网发电还未起步.不过.2008年北京[绿色奥运"部分用电将会由太阳能发电和风力发电提供. 太阳能光伏发电的最基本元件是太阳电池(片).有单晶硅.多晶硅.非晶硅和薄膜电池等.目前.单晶和多晶电池用量最大.非晶电池用于一些小系统和计算器辅助电源等.国产晶体硅电池效率在10-13%左右.国外同类产品效率约12-14%.由一个或多个太阳电池片组成的太阳能电池板称为光伏组件.2002年全球太阳电池和光伏组件产量约600MW.其中日本占45%.美国25%.欧洲约22%.日本是光伏产业发展最快的因家.在不到10年的时间里超过了美国.2001年世界10大太阳电池生产厂.日本就有4家.分别是夏普.京都陶瓷.三洋和三菱.欧美发达国家大都制订了[阳光计划".并采取措施鼓励居民安装太阳能发电系统.比如部分赠款.无息贷款和[种子基金"等.并以高出普通电价几倍的价格购买居民家中多余的太阳能电量. 我国太阳能光伏发电产业近几年发展较快.但总体规模较小.2002年太阳电池产量约SMW.累计装机容量达25MW.不到世界的1%.为配合西部大开发.我国政府实施了[阳光计划".[乘风计划"和[光明工程"等.利用太阳能发电和风力发电为解决西部广大无电地区农牧民生活生产用电.这一工程配套资金20多亿人民币.我国光伏发电产品的市场主要在西部.另有部分产品出日.如组件.小系统和日用太阳能电子产品等.由于国内太阳能电池晶片产量远远不能满足需求.许多厂家进日大量电池片封装组件.在光伏产业方面.深圳占有部分江山.产品加工能力.产品质量和销量在国内外都有一定的影响.政府应加大扶持力度.使之扩大规模发展成为产业群.进而成为深圳的一个经济增长点. 太阳能光伏发电产业增长迅速.不仅因为它是具有许多优点的清洁能源.一个更诱人的动因是.在太阳能与建筑一体化的过程中.太阳电池组件比太阳能热水器与建筑更有亲合力.太阳电池组件不仅可以作为能源设备.还可作为屋面和墙面材料.既供电节能.又节省了建材.国外己有非常好的案例.因此.太阳能光伏发电技术与建筑结合方面.将具有良好的经济效益.前途无限. (From the nets of photovoltaic power systems and grid type (pv) power system is very similar to the working principle, the only difference is the output power from the nets (systems are used directly to the public without powerSolar spectral heat generation and photovoltaic energy. No matter. The speed of development and the development prospects are missed. Solar-thermal power generation by photovoltaic (pv) power universal. May contact solar-thermal power wider. Usually folk say less often refers to the solar power generation is solar photovoltaic (pv) power. Referred. According to the pv solar battery using principle. The sun light directly into electricity grid. Both independent use or electricity. (pv) power system mainly consists of solar panels (component) controller and inverter. They are mainly composed of three by electronic components. Don't involve mechanical components. So. (pv) power equipment extremely refined. Reliable and stable life long. Installation and maintenance easy. Theory. (pv) power technology can be used for any need to power on the occasion to spacecraft... To household power stations to level. Small toys. Pv power can be everywhere. Now. (pv) power product is mainly used in three aspects: one is to provide electricity for the main power. Residents living without electricity supply power production and power of microwave reliever. Etc. In addition, also include some mobile power and standby power, solar daily electronic products such as all kinds of solar charger. And the solar energy lawn. Solar street lamps factory all sorts of lamps and lanterns, etc. It is implied in the developed countries has widespread implementation in grid generation yet......... But the 2008 Beijing Olympic Games "[green electricity will be part of solar and wind power. Solar pv power is the most basic elements of solar cells (film) have monocrystalline silicon polysilicon... And the film batteries. Monocrystalline or polycrystalline battery dosage of amorphous batteries used. A small system and computer aided power etc. Domestic crystal silicon efficiency in 10-13. The same products abroad efficiency about 12-14) by one or more solar -products composed of solar panels called pv. 2002, global solar cell and pv yield about 45% of 600 mw) in Japan, America, Europe, about 25% per photovoltaic industry development in Japan is the fastest for home. In less than 10 years than in the United States. 2001 world 10 big solar cells have 4. Japan's Kyoto were sharp.......... And mitsubishi sanyo Europe developed countries are developed [sunshine plan "and take measures to encourage the residents solar power system installation. For instance partial grants. An interest-free loan and [seed fund", etc. And the price several times higher than normal price of solar power people redundant. Our solar photovoltaic power industry in recent years. But the overall size of the rapid development of small solar cell production. 2002 total installed capacity, about SMW method of less than 1% of the world 25MW) to coordinate the western development. Our government implemented the "[[her plan" and "light engineering [etc. Use solar and wind power for solving the nomadic areas in western life without electricity production of electricity. This project matching funds more than 20 million yuan. Our pv power products market mainly in the west. Otherwise, such as a part of the product components. Small system. And the daily solar electronic products, etc. To the domestic solar wafer yield far cannot satisfy the requirement of many manufacturers into day. -products packaging components. In photovoltaic industry occupies part. Shenzhen. Products processing ability.
