An algorithm of linear simulation to calculate the static voltage stability limit of power system is presented. The sensitivity index is considered to be a criterion when the load is increased to the critical point. Several nonlinear factors such as reactive power limit of generators, static load characteristics, AGC and OLTC regulation are considered to make the solution of static voltage stability more practical. The voltage stability limit can be solved according to load increasing modes at different nodes, such as at single node, at an area or at all nodes. The voltage stability analysis program based on the algorithm is a useful and fast tool for power system operators and planner.
