如果功(gong)率(lv)分配(pei)出現較(jiao)大的不(bu)(bu)均衡(heng)，無(wu)論是(shi)有功(gong)功(gong)率(lv)還是(shi)無(wu)功(gong)功(gong)率(lv)，都不(bu)(bu)僅僅是(shi)影響柴油發(fa)電(dian)(dian)機(ji)組(zu)運行(xing)的效率(lv)和經(jing)濟型，而(er)且嚴重(zhong)(zhong)的話會引(yin)起整個(ge)電(dian)(dian)站的故障(zhang)。如果并聯發(fa)電(dian)(dian)機(ji)組(zu)的有功(gong)功(gong)率(lv)分配(pei)嚴重(zhong)(zhong)不(bu)(bu)平衡(heng)的話，深圳300kw發(fa)電(dian)(dian)機(ji)在(zai)負載(zai)(zai)(zai)總功(gong)率(lv)較(jiao)大的時(shi)候，往(wang)往(wang)是(shi)一(yi)臺發(fa)電(dian)(dian)機(ji)組(zu)已(yi)經(jing)滿載(zai)(zai)(zai)或者過(guo)載(zai)(zai)(zai)，而(er)另(ling)一(yi)臺發(fa)電(dian)(dian)機(ji)仍處于(yu)輕載(zai)(zai)(zai)狀態(tai)，這(zhe)樣就不(bu)(bu)能充分利用發(fa)電(dian)(dian)機(ji)組(zu)的容量，發(fa)揮整個(ge)電(dian)(dian)站的效能。

柴(chai)油(you)(you)發電(dian)機(ji)組(zu)(zu)過載不(bu)但會(hui)給(gei)柴(chai)油(you)(you)機(ji)或發電(dian)機(ji)帶來嚴重的(de)(de)危害，而且還會(hui)引起保(bao)護(hu)設備工作(zuo)，影(ying)響整個(ge)電(dian)站的(de)(de)運行。反之(zhi)，300kw發電(dian)機(ji)在(zai)負載總功率(lv)(lv)很小的(de)(de)時候，有功功率(lv)(lv)的(de)(de)不(bu)平衡(heng)又往往會(hui)在(zai)發電(dian)機(ji)組(zu)(zu)之(zhi)間引起有功環流，使有的(de)(de)機(ji)組(zu)(zu)轉(zhuan)入電(dian)動機(ji)狀態，這對柴(chai)油(you)(you)機(ji)同樣是(shi)不(bu)允(yun)許(xu)的(de)(de)。在(zai)柴(chai)油(you)(you)發電(dian)機(ji)組(zu)(zu)具有逆(ni)功率(lv)(lv)保(bao)護(hu)時，逆(ni)功率(lv)(lv)現(xian)象將引起逆(ni)功率(lv)(lv)跳閘，造成故障。對于負載變(bian)化(hua)頻繁且變(bian)化(hua)幅度較大的(de)(de)柴(chai)油(you)(you)機(ji)電(dian)站，以上(shang)的(de)(de)情況需要引起特別注意(yi)。
