火电机组深度调峰下的优化控制策略

Optimal Control Technology under Deep Peak Load Regulation of Thermal Power Units

截至目前,我国已经实现了多元化发电,但是火力发电依然是我国主要的发电方式,因此火电厂在我国总能源当中占有最大的比重,而火电机组调峰深度不足50%。我国北方冬季需要集中供热,而在这一时期北方地区的火电厂电力组调峰深度仅有10%~20%。如此低效的调峰深度对我国能源高效利用十分不利,对此我国急需要探寻更加先进的火电机组深度调峰技术途径,从而更好地适应新时期新能源战略发展需求,使新能源入网比例进一步扩大,同时兼顾大容量火电机组节能减排,提升火电机组深度调峰、灵活性,有效提升新能源入网。

Up to now,my country has achieved diversified power generation,but thermal power is still the main power generation method in my country.Therefore,thermal power plants account for the largest proportion of my country's total energy,and the peak shaving depth of thermal power units is less than 50%.In northern my country,central heating is needed in winter,and during this period,the peak shaving depth of thermal power plants in northern areas is only 10%-20%.Such inefficient peak shaving depth is very detrimental to the efficient use of energy in my country.For this reason,my country urgently needs to explore more advanced deep peak shaving technology for thermal power units,so as to better adapt to the new energy strategic development needs in the new era and increase the proportion of new energy into the grid.Further expansion,while taking into account the energy-saving and emission reduction of large-capacity thermal power units,is committed to improving the deep peak regulation and flexibility of thermal power units,and effectively improving the access of new energy to the grid.
