文章摘要:在大型電力網(wǎng)絡(luò)電氣傳動故障檢測優(yōu)化問題的研究中,由于系統(tǒng)的復(fù)雜性較高,處理起來具有一定難度,造成具有檢測周期長、耗時長、低信度的弊端,提出采用獨立變量分析優(yōu)化算法的大型電力網(wǎng)絡(luò)電氣傳動故障檢測方法。根據(jù)故障發(fā)生時的緊急程度,對故障進(jìn)行分類,建立電氣傳動的故障模型,依據(jù)相關(guān)理論對初始觀測數(shù)據(jù)進(jìn)行預(yù)處理,提高電氣傳動故障的檢測效率,根據(jù)獨立變量分析優(yōu)化算法對預(yù)處理后的觀測變量進(jìn)行分析,,提取特征向量,分析觀測數(shù)據(jù)偏離標(biāo)準(zhǔn)的程度,從而實現(xiàn)大型電力網(wǎng)絡(luò)電氣傳動故障的有效檢測。實驗結(jié)果表明,采用改進(jìn)算法進(jìn)行大型電力網(wǎng)絡(luò)電氣傳動故障檢測,能夠提高故障檢測的準(zhǔn)確率、降低檢測誤差,為大型電力網(wǎng)絡(luò)的安全提供數(shù)據(jù)支撐,滿足實際生產(chǎn)需求。
Abstr:A fault detection method of electric transmission for large power network is presented based on optimi- zation algorithm of the independent variables. Depending on the fault urgency, the fault is classified, a fault model of electrical transmission is set up, the initial observed data are preprocessed, and the efficiency of the electric transmis- sion fault detection is improved. The preprocessed variables are analyzed according to the optimization algorithm of the independent variables, the feature vector is extracted, the degree of deviation from the standard of observed data is analyzed, and the fault detection of electric transmission for large power network is effectively realized. The experi- mental results show that the proposed algorithm can improve the accuracy of fault detection and reduce the measure error.
