摘　　要：为解决中低负荷工况下的高耗能问题,某电厂进行了广义变频改造,并选取改造后的THA、75%THA和50%THA等3个典型工况进行了节能效果测试与研究。结果显示,在高负荷工况下,广义变频的节能效果并不显著;而在中低负荷工况下,广义变频的节能效果随着负荷的降低而增加。该研究表明,通过广义变频改造能够有效降低中低负荷工况下的能耗,同时该研究为AGC调频技术在深化节能改造方面的应用探索了道路。To address the issue of high energy consumption under low and medium load conditions,a power plant implemented generalized variable frequency(GVF)technology modifications.Energy-saving effectiveness tests and studies were conducted on three typical operating conditions after the modifications:THA,75%THA,and 50%THA.The results indicated that under high load conditions,the energy-saving effects of GVF technology were not significant.However,under low and medium load conditions,the energy-saving effectiveness of GVF increased as the load decreased.This study demonstrates that GVF modifications can effectively reduce energy consumption under low and medium load conditions.Additionally,the research paves the way for the application of AGC frequency regulation technology in further energy-saving improvements.
