摘要
针对吉林电网机组一次调频能力不足的问题,对一次调频控制策略进行分析,指出机组主蒸汽压力偏低、一次调频参数设置相对简单、压力拉回回路造成一次调频反调等缺陷,提出了增加压力修正环节,增加反调抑制逻辑,设计带负荷函数补偿的流量曲线的控制策略,提高了机组一次调频的质量,取得了较好效果。
Aiming at the problem of insufficient frequency modulation capability of Jilin power grid unit, this paper analyzes the primary frequency control strategy, points out that the main stream pressure of the unit is low, the setting of the primary frequency modulation parameter is relatively simple, the pressure pullback circuit causes a frequency offset and other defects, put foward that add pressure correction, increase the anti-suppression logic, design the control strategy with the load function compensation flow curve to improve the quality of primary frequency modulation in the unit, and achieved good results.
