建筑周期性负荷能效管理方法

摘要

通过分析周期性能耗设备的用能情况，确定周期性设备的能耗特点；用Fourier （傅立叶）级数的形式对建筑周期性设备的能耗进行描述；通过分析级数展开式系数对设备用能情况进行评估，及时发现设备用能异常和不合理的地方，同时可以区分周期性负荷周期波动原因是否属于正常用能情况；该方法解决了总量控制管理法无法查找到的问题，以及最大值管理法无法管理非峰值用能异常的问题。%　　Characteristics of energy consumption of periodic energy-consuming equipment for buildings are determined based on analysis of energy consumption;such energy consumption is described in the form of Fourier series and assessed through analysis on the expansion equation coefficient of Fourier series to timely find out abnormal and unreasonable energy consumption and identify whether the periodic fluctuation of periodic load is a result of normal energy consumption. Through this method, problems which cannot be identified through the total control method and abnormal off-peak energy consumption which cannot be controlled through the maximum control method are solved.
