【摘要】：為研究N-k故障下導(dǎo)致電力系統(tǒng)脆弱性惡化的關(guān)鍵線路,提出一種構(gòu)建關(guān)鍵線路模型的方法�；�于脆弱性概念和復(fù)雜網(wǎng)絡(luò)脆弱性理論,以電力系統(tǒng)最小失負(fù)荷率來表示電力網(wǎng)絡(luò)的實際傳輸效率,建立電力系統(tǒng)脆弱性模型;基于協(xié)同破壞效應(yīng)理論,結(jié)合N-k故障下故障集的脆弱性,建立故障情況下影響電力系統(tǒng)脆弱性的關(guān)鍵線路模型;考慮系統(tǒng)中兩兩相鄰線路可能具有相似的特點,提出基于分區(qū)劃分法的分析流程。IEEE 39節(jié)點系統(tǒng)算例仿真結(jié)果表明,所提模型和方法能夠有效篩選故障集的數(shù)目,并得出高脆弱線路具有低協(xié)同破壞效應(yīng)、高關(guān)鍵線路具有高協(xié)同破壞效應(yīng)和低脆弱性的結(jié)論。
[Abstract]:In order to study the critical circuit which leads to the deterioration of power system vulnerability under N-k fault, a method to construct the critical circuit model is proposed, which is based on the concept of vulnerability and the theory of complex network vulnerability. The actual transmission efficiency of power network is represented by the minimum load loss rate of power system, and a vulnerability model of power system is established, which is based on the theory of cooperative failure effect and the vulnerability of fault set under N-k fault. The critical circuit model which affects the vulnerability of power system under the condition of fault is established, and considering the similar characteristics of the two adjacent circuits in the system, an analysis flow based on partition method is proposed. The simulation results of IEEE 39-bus system show that, The proposed model and method can effectively screen the number of fault sets and draw the conclusion that high fragile lines have low cooperative failure effect and high critical lines have high cooperative failure effect and low vulnerability.
