膠體密封鉛蓄電池：風能和太陽能的儲能裝置
cell because these two power generation ways shall be influenced by the change of natural conditions and will be intermittent
and uncontrolled．The small wind energy and solar energy off-grid power generation systems usually adopt lead—acid battery
pack as their energy storage equipment．Now,the wind energy power generation unit has developed into M W level from KW
level，SO it requires the energy storage system be large．M eanwhile，because ofthe geography location lim it ofpower generation
system，energy storage system must feature with the characters of safety,reliability,cheap price and long life and must be
endowed with the full capacity to resist bad weathers and environments．
Based on the requirement of energy storage systems targeting at wind energy and solar energy power generation systems
風能和太陽能非并網(wǎng)發(fā)電系統(tǒng)都需要儲能電池．這是由于
這兩種發(fā)電方式受到自然條件變化的影響．而具有間歇性和不
可控性。小型風能和太陽能非并網(wǎng)發(fā)電系統(tǒng)普遍采用鉛蓄電池
組作為儲能裝置。目前，風力發(fā)電機組已由幾百千瓦級發(fā)展到
幾千千瓦級，這就要求儲能系統(tǒng)必需大型化。同時由于發(fā)電系
統(tǒng)地理位置的限制，儲能系統(tǒng)必需安全可靠，價格便宜、使用
壽命長并且有充分的抗惡劣天氣和使用條件的能力。
