subtranient value-
It includes four criterions of locating fault point ? “ transient zero sequence current amplitude law ”, “ stable base wave zero sequence current phase law ”, “ stable seventh harmonic zero sequence current phase law ” and “ s injection law ”. pointing out how the law locate the fault point to minimal fault section by applying these criterions gradually. the law will not only make up the blemishes existing in current methods for single - phase fault location in small current grounding system, but also locate the fault point to minimal fault isolating unit on fault line
該方法通過將所包含的四個定位判據- 「暫態零序電流幅值法」 、 「穩態基波零序電流方向法」 、 「穩態7次諧波零序電流方向法」和「 s信號注入法」 -進行有選擇地遞進使用，不僅有效彌補了目前已有小電流接地系統單相接地故障選線的缺陷，更將故障定位在故障線路最小故障區段。5 ) this dissertation presents new predictive models for the transient stability and small signal stability based on support vector machine theory that can solve the problems such as finite samples. a new method of feature selection and sample condensation is proposed to build predictive model which improves the practicability of the model greatly
5 ）論文首次利用基於小樣本技術的支持向量機理論，設計了新的暫態穩定、小擾動穩定特徵值預測模型，提出了新的適合預測模型構建的特徵選擇、數據采樣策略，提高了模型的實用性。
