Abstract

This paper presents and studies a static model for synchronous generators with voltage dependent reactive power limits due to maximum stator current, maximum and minimum rotor (field) current as well as maximum rotor angle (underexcitation) limiters. The proposed generator model for static voltage stability studies can be included in an ordinary power flow program, and results from studies on a test system with twenty generators are presented. The influence of voltage dependent reactive power limits is compared with fixed (conventional) limits, by use of the minimum singular value of the power flow Jacobian matrix and related submatrices as indicators of the static voltage stability limit.
