Abstract

According to the power flow of prevailing operating modes in Sichuan power grid in 2003

Steady-state stability margin under several typical operating modes is calculated and the weakest voltage area in power system is analyzed using voltage stability analysis software. The conclusion can provide valuable information for avoidance of voltage collapse and security of Sichuan power grid. And the calculation results have proved the software is accurate and practical.
