用于瞬时功率分解和估计的系统以及方法
Abstract:
一种用于分解并估计由单个电插座(10)供电的电负载(4、6、8)的功率消耗的系统(2)。系统包括具有程序(14)的处理器(12)；与处理器协作的电流传感器(16)，用于测量由单个电插座供电的电负载的聚合的电流波形(18)的一个线周期的样本；以及与处理器协作的电压传感器(20)，用于测量由单个电插座供电的电负载的电压波形(22)的一个线周期的样本。处理器程序将所聚合的电流波形和电压波形的一个线周期的所测量的样本转换成单个电插座的聚合的电压-电流轨迹(24)，以及根据一个线周期的所聚合的电压-电流轨迹提供多个不同类别的电负载的功率消耗的即时分解。
Abstract(English):

A system (2) disaggregates and estimates power consumption of electric loads (4,6,8) powered by a single electrical outlet (10). The system includes a processor (12) having a routine (14); a current sensor (16) cooperating with the processor to measure samples for one line cycle of an aggregated current waveform (18) for the electric loads powered by the single electrical outlet; and a voltage sensor (20) cooperating with the processor to measure samples for the one line cycle of a voltage waveform (22) for the electric loads powered by the single electrical outlet. The processor routine transfers the measured samples for the one line cycle of the aggregated current waveform and the voltage waveform into an aggregated voltage-current trajectory (24) for the single electrical outlet, and provides an instantaneous decomposition of power consumption for a plurality of different categories of the electric loads from the aggregated voltage-current trajectory for the one line cycle.
