高负荷密度区域电网短路电流水平与源-网-荷结构的耦合关系量化研究
Quantitative Research on the Coupling Between Short-circuit Current Level and Source-grid-load Structure in High Load Density Regional Power Grid
摘要
Abstract
Excessive short-circuit current(SCC)has become a core operation risk in power systems of high load density areas.With the load density and power source distribution as independent variables,this paper proposes a parametric modeling method to generate the theoretical grid structure,where the network power flow analysis is obtained by the maximum flow algorithm.On this basis,a systematic method is established to quantitatively evaluate the impact of key factors on the SCC level,including the load density,the proportion of local synchronous generator,and the proportion of external DC power injection.Based on the theoretical model,variation patterns of the SCC level and distribution in high load density areas is analyzed.Furthermore,a series of planning countermeasures,including reducing the tie lines,reducing local synchronous generators,optimizing the network topology etc.,are evaluated for their effectiveness in reducing SCC.The study provides a good reference for power grid planning in high load density areas considering the SCC level controlling.关键词
