【摘要】：以電流信號(hào)的頻域分析為基礎(chǔ),結(jié)合非侵入監(jiān)測(cè)負(fù)荷運(yùn)行的電流模型,利用單獨(dú)作用時(shí)電流信號(hào)的頻譜分量會(huì)完整包含于混合電流頻譜中,提出一種基于模板濾波的居民負(fù)荷非侵入式快速辨識(shí)算法。通過先驗(yàn)方式獲取用電網(wǎng)絡(luò)各負(fù)荷的特征電流形成特征濾波器,對(duì)其頻譜分量進(jìn)行0-1賦值得到對(duì)應(yīng)的模板濾波器。利用模板濾波器對(duì)非侵入采集模式下的混合電流信號(hào)濾波,通過對(duì)濾波后頻率分量的量化判決確定負(fù)荷的運(yùn)行狀態(tài)。利用實(shí)際采集的用電數(shù)據(jù)驗(yàn)證了該算法的有效性,能夠準(zhǔn)確判斷負(fù)荷運(yùn)行狀態(tài)。此外,算法利用快速傅里葉變換(FFT)即可實(shí)現(xiàn),便于實(shí)際中硬件封裝。
[Abstract]:Based on the frequency domain analysis of the current signal and the current model of non-intrusive monitoring load operation, the spectrum components of the current signal will be completely included in the mixed current spectrum when the current signal is acted on alone. A fast identification algorithm of resident load based on template filter is proposed. The characteristic current forming characteristic filter of each load of electric network is obtained by a priori method, and the corresponding template filter is obtained by 0-1 assignment of the spectrum component of the filter. The mixed current signal in the non-intrusive acquisition mode is filtered by the template filter, and the operation state of the load is determined by quantifying the frequency component after the filter. The validity of the algorithm is verified by the actual data collected, and the load state can be judged accurately. In addition, the algorithm can be realized by fast Fourier transform (FFT), which is convenient for hardware encapsulation.
