摘要
在区域电网特高压互联、风电、光伏等新能源比重越来越大的新形势下,火电机组的深度调峰已成为常态,深调模式下如何准确、快速的实现一次调频面临更大的挑战。通过研究网频动态调整、负荷动态补偿调整、调阀流量特性曲线自动优化形成一次调频智能控制系统,提升了机组一次调频指标,同时减少了机组一次调频期间的无效扰动,提升了机组运行的安全性和经济性。
In the new situation where the proportion of new energy such as ultra-high voltage interconnection,wind power,and photovoltaics in regional power grids is increasing,deep peak shaving of thermal power units has become the norm.How to accurately and quickly achieve primary frequency regulation in deep regulation mode faces greater challenges.Traditional primary frequency regulation uses the actual speed signal of the unit as the basis for judging the primary frequency regulation action.By studying the dynamic adjustment of grid frequency,load dynamic compensation adjustment,and automatic optimization of valve flow characteristic curves,intelligent primary frequency regulation is formed.The control system has improved the primary frequency regulation indicators of the unit,while reducing ineffective disturbances during the primary frequency regulation period,improving the safety and economy of the unit operation.
