一、通信電源用了什么新技術

隨著移動通信(xin)業的不(bu)斷發展壯大，對通信(xin)電源(yuan)的要求也(ye)越來越高(gao)。傳統的通信(xin)電源(yuan)由于某些(xie)方面存(cun)在一系列不(bu)足(zu)(zu)，已(yi)不(bu)能滿足(zu)(zu)新的需要。新技術的應(ying)(ying)用可以有(you)效優化(hua)通信(xin)電源(yuan)的性能，提高(gao)電源(yuan)的可靠性和穩定(ding)性，從而(er)滿足(zu)(zu)更加廣泛的應(ying)(ying)用需求。

1、燃料電池技術

燃料電池技術是一種新型的電力技術，逐漸被廣泛應用于通信電源中。燃(ran)料(liao)(liao)電(dian)(dian)(dian)池(chi)(chi)(chi)可以將化(hua)學能(neng)(neng)轉換為電(dian)(dian)(dian)能(neng)(neng)，為通(tong)信設備供應(ying)(ying)電(dian)(dian)(dian)能(neng)(neng)，從而能(neng)(neng)夠為通(tong)信系統提供長時(shi)間(jian)的電(dian)(dian)(dian)力(li)支持，同時(shi)還能(neng)(neng)夠減少(shao)對環境的污(wu)染。目前(qian)，燃(ran)料(liao)(liao)電(dian)(dian)(dian)池(chi)(chi)(chi)技術的發(fa)展主要集中在(zai)(zai)兩個方面(mian)：燃(ran)料(liao)(liao)電(dian)(dian)(dian)池(chi)(chi)(chi)的低溫化(hua)和燃(ran)料(liao)(liao)電(dian)(dian)(dian)池(chi)(chi)(chi)的中高溫化(hua)。低溫燃(ran)料(liao)(liao)電(dian)(dian)(dian)池(chi)(chi)(chi)具有響應(ying)(ying)快、環境適應(ying)(ying)能(neng)(neng)力(li)強(qiang)等優勢(shi)；而中高溫燃(ran)料(liao)(liao)電(dian)(dian)(dian)池(chi)(chi)(chi)則具有高效(xiao)、連續穩定工作等特點。燃(ran)料(liao)(liao)電(dian)(dian)(dian)池(chi)(chi)(chi)的應(ying)(ying)用(yong)(yong)，不僅(jin)在(zai)(zai)通(tong)信電(dian)(dian)(dian)源領域，也用(yong)(yong)于(yu)其他領域。

2、太陽能技術

在通信電源中，太陽能技術被廣泛應用。太陽能技術在環保、安全等方面具有明顯的優勢，可以有效解決傳統的通信電源存在的一系列問題。太陽能電池的(de)穩定(ding)性不斷提(ti)高，但(dan)也存在(zai)不可(ke)(ke)忽(hu)視的(de)缺點，如夜間或天氣惡(e)劣時(shi)無(wu)法提(ti)供足夠的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。為(wei)了解(jie)決這些問(wen)題(ti)，通(tong)(tong)信(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)逐漸采取(qu)多(duo)種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)設備的(de)結(jie)合(he)方(fang)式(shi)，例(li)如太陽(yang)(yang)能與蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池、交流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)等共同使(shi)用。隨著通(tong)(tong)信(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)產業(ye)的(de)發展(zhan)，對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)系統(tong)(tong)的(de)要(yao)求也越來(lai)越高。為(wei)了增強(qiang)系統(tong)(tong)備份時(shi)間和穩定(ding)性，通(tong)(tong)信(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)在(zai)本地儲能技(ji)術上取(qu)得(de)了很大的(de)進展(zhan)，成為(wei)重要(yao)的(de)技(ji)術趨勢。在(zai)過去，燃料(liao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池和太陽(yang)(yang)能電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池都是利用儲存電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷來(lai)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力。但(dan)是，由于燃料(liao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池和太陽(yang)(yang)能電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)特(te)殊性質，一旦電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷水平降(jiang)低，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力產生率(lv)就會下降(jiang)。因此，需要(yao)為(wei)系統(tong)(tong)提(ti)供穩定(ding)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。儲能技(ji)術主(zhu)要(yao)有(you)多(duo)種(zhong)，如超(chao)級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)器、蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池等。在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量方(fang)面，蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池可(ke)(ke)持(chi)續提(ti)供幾個小時(shi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量，而超(chao)級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)器只能維持(chi)數(shu)分(fen)鐘(zhong)。因此，在(zai)通(tong)(tong)信(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)領域，使(shi)用超(chao)級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)器與蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池相(xiang)結(jie)合(he)等科(ke)學組合(he)可(ke)(ke)以做出(chu)最優(you)的(de)選擇。

二、通信電源系統供電方式有哪些

為了保證(zheng)供(gong)電(dian)(dian)的(de)穩(wen)定、可靠和安全(quan)的(de)，根據不(bu)(bu)同的(de)應用要求，通信電(dian)(dian)源可以采用不(bu)(bu)同的(de)供(gong)電(dian)(dian)方式(shi)。集中供(gong)電(dian)(dian)、分散(san)供(gong)電(dian)(dian)和混(hun)合供(gong)電(dian)(dian)是采用的(de)典型(xing)的(de)三(san)種供(gong)電(dian)(dian)方式(shi)。

1、集中(zhong)供電是指(zhi)通信(xin)局（站）中(zhong)所有通信(xin)設備由一個集中(zhong)的直流電源供電。

2、分散(san)供電方式電源系統設置多個(ge)直流供電系統，分別給局（站）內一部(bu)分通信設備(bei)供電。

3、混合供電方(fang)式電源(yuan)(yuan)系(xi)(xi)統(tong)，在光纜中繼站、微波無(wu)人值守中繼站和(he)移動(dong)通信基站等地方(fang)，可以采(cai)用交流電源(yuan)(yuan)和(he)太(tai)陽電池(chi)（或其他(ta)能源(yuan)(yuan)）相結合的(de)混合供電方(fang)式電源(yuan)(yuan)系(xi)(xi)統(tong)進行供電。該系(xi)(xi)統(tong)由太(tai)陽電池(chi)方(fang)陣、低壓市電、蓄電池(chi)組(zu)、整(zheng)流和(he)配電設備以及移動(dong)發(fa)電機組(zu)成。
