摘要
为了确保同步发电机稳定运行于最大功率角状态,又不发生失步,通过对中小型同步发电机失步原因的静态分析和动态分析,提出了如何确保同步发电机稳定运行于最大功率角状态而不失步的方法。并对龙溪水电站机组进行了最大功率角限值的具体测量,使机组在最大功率角状态下安全、连续、稳定运行成为现实。因此,龙溪水电站于2000年成为台州电网第一家按电压考核的水电站,每年可减少因无功功率扣款近100万元。
To ensure the synchro-generator running steadily at the stage of max. power angle without causing any failure, and fully utilize the water resources and to soften the current electricity shortage, we hereafter claim for the method ensuring the synchro -generator running steadily at the stage of max. power angle by static ＆ dynamic analysis, furthermore, to realize the fact of safely, continuously and steadily operation under improving power angle through our carefully measuring the limitation of max-power angle to Longxi generator set. Hence, in year 2000, Longxi Water Power Station was awarded as the first one scored by voltage in Taizhou, which can save around one million RMB annually.
