| 摘 要： | 针对大型电力系统输电能力计算问题，提出了一种改进的PV曲线求取方法，它较好地考虑了受电侧负荷增长方式与发电侧发电机功率调度方式。在追踪PV曲线的过程中，改进的局部参数化方法被用于消除功率传输极限点附近潮流方程的病态现象。所提出的电压定步长下降控制思想提高了曲线的追踪效率，实现了自适应步长控制。500母线系统的计算证实了该方法的有效性。

| Abstract: | A m odified PV curve tracing method is proposed in this paper for the calculation of power transfer capability of large- scale systems. This m ethod can easily take into account the way of load changing in receiving areas and the mode of power dispatch am ong generators in sending areas.A local parameterization method is modified to trace the PV curve,which perfectly eliminates the illness of power flow equations near the power transfer limit.In addition,a sim ple method called constant step voltage decline is presented to im plem ent the auto- adaptive step length control. The effectiveness of this modified method is testified by a5 0 0 - bus exam ple system.
