发电机额定电压由于电力线路允许的电压偏差一般为+-5%,即整个线路允许有10%的电压损耗,因此为了维持线路的平均电压额定值,线路首端的电压可较线路额定电压高5%,而线路末端电压可较线路额定电压低5%。所以发电机额定电压按规定应高于同级电网额定电压5% 一般发电机根据装机容量的不同,发电机出口电压等级有6.3KV,10.5KV,13.8KV,18.5KV。
发电机额定电压指电机在额定工况下运行,其端子电压整流后并扣除连接线压降的直流输出电压。
Refers to the electrical generator rated voltage at rated operation conditions, the terminal voltage after the rectifier and the deduction of the DC link output voltage drop.
另外,当发电机以额定电压啊,电流运行时,其出力(输出功率)频率允许在上下5%内跳动。
In addition, the output frequency of a motor generator set shall not vary by more than 5% when operated at rated output voltage and current.
