基于VST的电压稳定分岔分析
A VST-Based Analysis for Voltage Bifurcation Stability
摘要
Abstract
A novel Matlab-based bifurcation analysis toolbox for voltage stability, named voltage stability analysis toolbox (VST), is presented. The features of its friendly graphic interface and open source are described in detail. Based on numerical and symbolic computation, a combinational algorithm integrating Newton-Raphson method and Newton-Raphson-Seydel method is adopted to research the bifurcation and voltage stability problems. Main functions of VST include power flow calculation, bifurcation analysis,singularity and eigenroot analysis, dynamic time-domain simulation and so on. VST contributes to understand power system voltage stability and nonlinear bifurcation phenomena.Simulation results of a 3-machine 5-bus system and IEEE 30-bns system verify the practicability and effectiveness of the presented toolbox in voltage stability analysis.关键词
