3.2預測風電功率

由于現如今大規模風電并網對電力系統和電網調度的安全運行產生了嚴重影響，而對風電功率進行預測能使這個問題得到有效緩解。風電的特性是隨機性和波動性，這個特性使得預測風電功率需以大量的歷史數據作為支撐，此類數據主要包括風電機組信息、地貌形勢、風電場實時和歷史輸出功率數據、實時和歷史測風塔等數據。其中采集的風塔歷史數據的時間分辨率短則超過10min，時長則超過1年；通過風電場采集的歷史輸出功率數據的時間分辨率要超過5min，數據的時長要超過1年。面對大量的歷史數據，此時就需要建立可靠的預測模型來對風電功率進行預測，通過選擇不同的時間尺度，結合實際工程應用需求，嘗試多種預測模型對風電功率進行預測，以便得到更精準的預測結果。無線計量電表無需段電操作安裝磁鋼取電485

由于現(xian)在電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)仍然存(cun)在低電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)問題，主要原因是整(zheng)個(ge)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)系(xi)(xi)統升(sheng)級較慢，以(yi)及用(yong)電(dian)(dian)(dian)(dian)(dian)負(fu)(fu)荷的(de)大(da)大(da)增加，這樣對用(yong)戶的(de)正常(chang)用(yong)電(dian)(dian)(dian)(dian)(dian)造成了(le)負(fu)(fu)面影(ying)響。利(li)用(yong)大(da)數(shu)據技術能定位配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)低電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)的(de)相(xiang)關信(xin)(xin)(xin)息(xi)可通(tong)過用(yong)電(dian)(dian)(dian)(dian)(dian)信(xin)(xin)(xin)息(xi)采集(ji)系(xi)(xi)統和SCADA系(xi)(xi)統進行收(shou)集(ji)[7]，這些相(xiang)關信(xin)(xin)(xin)息(xi)如(ru)變壓(ya)(ya)(ya)器和線路的(de)電(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)斷貨負(fu)(fu)荷類型、功率因數(shu)等參數(shu)。與(yu)此同時，與(yu)配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)相(xiang)關聯的(de)無功補償、負(fu)(fu)載率、供電(dian)(dian)(dian)(dian)(dian)半徑、配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)結構、故障情(qing)況等信(xin)(xin)(xin)息(xi)，為了(le)深度了(le)解電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)低電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)原因，采用(yong)數(shu)據挖(wa)掘模型對配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)低電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)影(ying)響因素(su)進行關聯分析，提升(sheng)了(le)配(pei)(pei)(pei)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)合格(ge)率，對電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)的(de)安全運行給予(yu)保障。

3.4預警評(ping)估配電網(wang)重過載風(feng)險

伴隨著用電量即電力需求的大幅度增長，傳統“輕配重輸"的工程建設模式已與現如今的發展需求不太符合，主要原因是常常會出現重過載的問題，因此不但對供電質量失去了保障，還影響了配電網的正常運行[8]。為了更方便的獲取配電變壓器和輸電線路的歷史和實時的三相電壓、電流和功率因素等相關信息，可通過這些系統來獲取，如用電信息采集系統、OMS、SCADA、AMI、OMS、關聯營銷業務等系統。然后采用綜合分析的方法來評估配電變壓器的相關特性，如容載比、配電網元件故障率、線路間負荷轉移能力等。無線計量電表無需段電操作安裝磁鋼取電485
