on. the functionCommercialization of pv system controller, its function characteristics are different, can undertake choosing according to the following controller function characteristic. (1) temperature pensation: according to environment temperature to adjust the battery charging current. (2) the load circuit breaker: when if there is any difficulty cannot satisfy the needs or replace the fuse, fuse can substitute for load. (3) low voltage alarm: when the battery charged state is lower than in the electricity at ordinary times, can hear the warning sound. (4) low voltage disconnect: when the battery to discharge in the electricity at ordinary times, cut off the load automatically. (5) the voltage indicator: analog or digital display battery voltage, indicates the charged state of storage battery. (6) current indicator: analog or digital display solar cell phalanx output current and load current. (7) ampere hour meter: digital storage battery is power or battery. (8) backup start charging control: automatically start backup power supply, recharging the battery into the line. (9) square power shunt regulator: excess phalanx charging power to bypassThe important load, such as electric water heater, etc. Rizhao monitor (10) : measurement of available solar radiation intensity. (11) load chronograph: load with the clock regularly, line in the shipment time is applied to load, such as security lighting, etc. (12) rechargeable electric instructions: to achieve full of battery voltage, light emitting diodeLights up. (13) automatic equalizing charge: automatically on a regular basis for both constant charging battery.。A (12)充 電指示:蓄電池達(dá)到充滿電壓時(shí) ,發(fā)光二極管指示 燈點(diǎn)亮。 (4)低電壓斷開(kāi):當(dāng)蓄電池放電至予置電平時(shí),自動(dòng)切斷負(fù)載。 (2)信號(hào)燈或蜂鳴器動(dòng)作報(bào)警 ,顯示蓄電池 電壓過(guò)低。 2.4 脈沖控制器 脈沖控制器以“斬波”方式工作,對(duì)蓄電池進(jìn)行脈沖充電脈沖控制器的核心部件是一個(gè)受充電電壓調(diào)制的“充電脈沖發(fā)生器”。串聯(lián)控制器使用傳感器來(lái)代替二極管通斷電路,以防止夜間的“反向泄漏”。旁路控制器的功率晶體管有帶翅的散熱器,幫助發(fā)散熱量。但是這些方法由于充電方式單一加上控制策略不夠完善,都存在一定的局限性。太陽(yáng)能光伏發(fā)電現(xiàn)已成為新能源和可再生能源的重要組成部分,也被認(rèn)為是當(dāng)前世界最有發(fā)展前景的新能源技術(shù)。Technology,Seetanah 附件1:外文資料翻譯譯文 太陽(yáng)能發(fā)電技術(shù) —— 光伏發(fā)電系統(tǒng)控制器1 太陽(yáng)能充放電控制器現(xiàn)狀太陽(yáng)能作為新能源有著巨大的優(yōu)勢(shì),所以世界各國(guó)都在努力研發(fā)新技術(shù)進(jìn)行獲取,比較成熟的是太陽(yáng)能光伏發(fā)電技術(shù)。目前,控制器常用的蓄電池充電法包括三種:恒流充電法、階段充電法和恒壓充電法。旁路控制器的電路 系 統(tǒng)監(jiān)控蓄電池電壓,當(dāng)達(dá)到標(biāo)志著蓄電池充滿的予置電平時(shí)過(guò)充電流將被功率晶體管旁路到電阻器,將多余的額外功率轉(zhuǎn)變?yōu)闊?。合成一體的內(nèi)置定時(shí)器,在充電過(guò)程終Lr至蓄電池組放電終止期間.進(jìn)行恒壓充電循環(huán)。多階控制器需耍適 當(dāng)?shù)耐L(fēng) .通常這種控制器設(shè)一個(gè)繼電器開(kāi)關(guān) ,防止夜 的“反向泄漏”??刂破鞣乐剐铍姵剡^(guò)放電的措施有: (1)在達(dá)到予置的待充電電平時(shí) ,斷開(kāi)負(fù)載。 (3)低電壓報(bào)警器:當(dāng)蓄電池荷電狀態(tài)低于予置電平時(shí),可 聽(tīng)到警告聲響。 (11)負(fù)載記時(shí)器 :定時(shí)負(fù)載用的記時(shí)鐘 ,用于需要予置運(yùn) 行時(shí)間的負(fù)載,例如安全警戒照明燈等。16
