摘　　要：为降低发电厂电能的利用率,减少由于用电峰值引起的能源浪费,提出火力发电厂低负荷调峰控制技术研究。首先,建立火力发电厂能量模型,分析其主要能量分布,并确定最佳真空下的循环水运行方式,确定最低负荷,计算循环水的能量消耗,并建立火力发电厂模型的约束条件,以此实现对发电厂的调峰控制。并进行实验测试,实验结果表明,所提方法最高降低能量产出120WM,且电能有效利用率基本稳定在90%以上,具有良好的控制效果,对于该领域的研究具有一定的参考价值。In order to reduce the utilization rate of electric energy in power plants and reduce the energy waste caused by the peak value of power consumption, the control technology of low load peak shaving in thermal power plants is proposed. Firstly, the energy model of thermal power plant is established, the main energy distribution is analyzed, the circulating water operation mode under the optimal vacuum is determined, the minimum load is determined, the energy consumption of circulating water is calculated, and the constraint conditions of thermal power plant model are established, so as to realize the peak load regulation control of power plant. The experimental results show that the proposed method can reduce the energy output up to 120 wm, and the effective utilization rate of electric energy is basically stable at more than 90%, which has a good control effect, and has a certain reference value for the research in this field.
