摘　　要：随着新能源市场的逐步扩大,火力发电厂一次调频的动作频率越来越高,同时也增加了一次调频的考核次数,火电机组承受着巨大的考核压力。机组动作时刻与考核时刻不同步是火力发电厂面临的一大难题,为了提高一次调频的正确动作率,在保证机组安全性的前提下,提高转速测量精度是保证一次调频正确动作的有效办法,才能为电厂减少大量考核。With the gradual expansion of the new energy market,the operation frequency of primary frequency regulation in thermal power plants is becoming more and more frequent,which also increases the number of times the primary frequency regulation is assessed,and thermal power units are under great assessment pressure.In order to improve the correct operation rate of primary frequency regulation,improving the accuracy of speed measurement is an effective way to ensure the correct operation of primary frequency regulation under the premise of ensuring the safety of the unit,in order to reduce a large number of assessments for power plants.
