| Abstract: | Based on analysis of the critical collapse point characteristics of the alternating current circuit, this paper determines the boundary of the critical voltage collapse for the alternating current circuit branch, and proposes a calculating method of voltage stability margin index based on operating characteristics of alternating current circuit. The calculation example shows that this method effectively avoids the power flow convergence when close to the critical voltage collapse point. |
