Abstract

Abstract: Power system transit stability analysis is performed in two typical operation modes of Xinjiang power grid before and after interconnection with Northwest grid by using PSASP simulation package. The simulation results show the change of stability characteristics after interconnection. The interconnection improves power angle, frequency and voltage stability but reduces thermal stability. Technical measures are investigated and proposed to guarantee power grid operation safety and stability.

Key words: interconnection, stability analysis, stability control measure
