摘要

非侵入式负荷监测（NILM）是未来电力负荷监测的重要发展方向之一。不同类型电力负荷在投切过程中，通常会表现出独特的暂态特征。据此，NILM能够克服利用负荷稳态特征信息进行负荷辨识的局限性，实现对整个变电站、建筑物内部负荷集群的分解与分析。提出了一种信号预处理算法———基于滑动窗的双边累积和（CUSUM）暂态事件自动检测算法，它能根据相关信号准确检测到负荷投切等引起的暂态过程、发生时刻等重要信息，并触发相关程序把暂态信息记录下来，然后送给后台高级应用程序作进一步处理。算例仿真表明了所述算法的有效性。

Abstract

Non-intrusive load monitoring（NILM） is one of the most promising technologies for load monitoring. Different classes of loads have unique observable transient profiles during the turn on/off process. With these transient profiles， NILM will be able to overcome the limitations of the algorithm in identifying the operation of the loads with the steady state load information， realizing decomposition and analysis of the cluster loads in the entire substation or a building. NILM should be able to capture the transients automatically and trigger the related program to save the transient data for further analysis. A novel sliding window version two-sided cumulative sum（CUSUM） algorithm is proposed for detecting the transients. Simulation results show the feasibility of the algorithm proposed.
