摘要
求取电力系统电压稳定极限必须考虑发电机的无功限制，为此在分析最大定子电流约束和最大励磁电流约束对发电机无功输出影响的基础上，比较处理负荷静态特性的方法，通过计及发电机无功输出的电压倚赖特性，提出了一种处理发电机无功越限的新方法，并给出了该方法在连续潮流计算中的实现。通过一个计算实例分析比较了几种类似方法，证明了所提方法的优越性。
Generator reactive power limitation must be considered in calculating voltage stability proximity. A new algorithm used to treat the generator reactive power limit violation is proposed in this paper. The method is based on voltage dependent reactive limits of generator due to maximum stator current and maximum rotor current limits. Its implementation on continuous power flow study is presented. Other treatment methods are also discussed by an example.
