电力物联网中非侵入式电力负荷模糊辨识系统

Non intrusive load monitoring (nilm) system refers to the installation of monitoring equipment at the power entrance. By monitoring the voltage, current and other signals, the type and operation of single load in the load cluster can be analyzed. The non-invasive load monitoring analysis methods can be roughly divided into two categories: one is based on the steady-state characteristics of the load, the other is based on the transient characteristics of the load. The steady-state characteristics mainly refer to the steady-state fundamental wave and harmonic power of the load. Transient characteristics mainly refer to the change rules of voltage, current and other signals at the moment of load opening, such as transient waveform and its structure. According to the comparison of various load identification methods, it can be concluded that the load identification based on non-invasive load monitoring standards can be divided into two steps: the first step is to collect the voltage, current, power, switching events and other information of the load by using the detection device; the second step is to process the collected information with the load model in the database by using different theoretical algorithms Match to identify the type of load. 非侵入式负荷监测（non-intrusive load monitoring, NILM）系统，是指在电力入口处安装监测设备，通过监测该处的电压、电流等信号就可以分析得到负荷集群中单个负荷的种类和运行情况。 非侵入式负荷监测分析方法大致可以分为两大类，一是基于负荷稳态特征的分析方法，二是基于负荷暂态特征的分析方法。稳态特征主要是指负荷的稳态基波、谐波功率等特征。暂态特征主要指那些负荷开启瞬间的电压、电流等信号的变化规律，如暂态波形及其结构等。 根据比较各种负荷辨识方法可以认为，以非侵入式负荷监测标准进行负荷辨别主要可以分为两个步骤：第一步：使用检测装置，对负荷的电压、电流、功率、开关事件等信息进行采集，第二步：运用不同理论的算法对采集信息进行处理，与资料库里的负荷模型进行匹配以辨识负荷种类。
