摘要
随着新能源的大规模开发及并网发电,由于新能源的输出功率存在较强波动特性,燃煤发电机组需要随时配合电网进行功率调度.随着电网峰谷差不断增大,火力发电机组调峰愈加频繁,且调峰负荷变化幅度越来越大.基于调峰过程中运行数据,分析运行参数的相关性,总结机组数据相关度,用以改进调峰策略,实现高效调峰.结果表明:机组负荷与再热压力、调压两个参数呈强相关,且具有线性正相关的关系.
With the large-scale development of new energy and grid-connected power generation,due to the strong fluctuation characteristics of the output power of renewable energy,coal-fired units need to cooperate with the power grid for power dispatching at any time. With the increase of peak-valley difference of power grid,the peak regulation of thermal power generation units becomes more frequent,and the variation of peak regulation load was larger.Based on the operation data in peak regulation process,the correlation of operation parameters was analyzed,and the correlation of unit data was summarized to improve peak regulation strategy and realize efficient peak regulation. The results showed that the unit load is strongly correlated with reheat pressure and regulating pressure,and has a linear positive correlation.
