发电(dian)(dian)(dian)量(liang)(liang)指电(dian)(dian)(dian)站(zhan)机组在一定(ding)时期(qi)内(nei)生产(chan)并由发电(dian)(dian)(dian)机端(duan)电(dian)(dian)(dian)能(neng)表计(ji)量(liang)(liang)的(de)(de)电(dian)(dian)(dian)能(neng)量(liang)(liang)并扣除(chu)发电(dian)(dian)(dian)机组励磁用电(dian)(dian)(dian)量(liang)(liang)后的(de)(de)电(dian)(dian)(dian)量(liang)(liang)。上(shang)网电(dian)(dian)(dian)量(liang)(liang)指电(dian)(dian)(dian)站(zhan)在一定(ding)时期(qi)内(nei)生产(chan)的(de)(de)、售电(dian)(dian)(dian)方(fang)与购电(dian)(dian)(dian)方(fang)产(chan)权(quan)分界点的(de)(de)各关(guan)口计(ji)量(liang)(liang)点电(dian)(dian)(dian)能(neng)表计(ji)量(liang)(liang)的(de)(de)电(dian)(dian)(dian)量(liang)(liang)之和。目前(qian)，按照公(gong)司(si)与电(dian)(dian)(dian)网公(gong)司(si)签订的(de)(de)购售电(dian)(dian)(dian)合同约定(ding)，售电(dian)(dian)(dian)量(liang)(liang)就是上(shang)网电(dian)(dian)(dian)量(liang)(liang)。
上(shang)网电(dian)量(liang)与(yu)发(fa)电(dian)量(liang)之差为厂用(yong)(yong)(yong)电(dian)，厂用(yong)(yong)(yong)电(dian)主(zhu)(zhu)要(yao)包括(kuo)发(fa)电(dian)机(ji)组正常发(fa)电(dian)必(bi)须(xu)的(de)机(ji)组辅助设备(bei)的(de)厂用(yong)(yong)(yong)动力与(yu)照(zhao)(zhao)明、主(zhu)(zhu)变压器等设备(bei)的(de)损耗，是(shi)电(dian)力生产(chan)所必(bi)须(xu)的(de)正常损耗。为有效降低厂用(yong)(yong)(yong)消(xiao)耗，在三峡工(gong)程设计中(zhong)对厂房等生产(chan)区(qu)(qu)域采用(yong)(yong)(yong)了(le)节(jie)能照(zhao)(zhao)明的(de)措施(shi)，在运行管理(li)中(zhong)建立了(le)办公区(qu)(qu)域空调(diao)温度(du)控(kong)制、照(zhao)(zhao)明节(jie)电(dian)等管理(li)制度(du)，力争将厂用(yong)(yong)(yong)消(xiao)耗控(kong)制在最低限度(du)。
