| 摘 要： | 对基于电网潮流计算的跟踪等值技术中的参数范围问题进行了探讨，发现在运行轨迹的某些区段可以出现负电阻参数，从非线性模型逐步线性化方法入手，进行详细分析后，提出PV节点发电机模型的非线性是电网跟踪等值参数中出现负电阻问题的重要原因，并指出应如何理解负电阻问题。

| Abstract: | The range of tracking equivalent parameters obtained by power flow calculation is discussed in this paper.Negative resistance is found on some section of operating trace.A fter analyzing this question by the method of linearizing the nonlinear model of an every node,it is presented that the nonlinear in generator model of PV node is the important reason of negative resistance appearance.In addition,how to understand the question of negative resistance is indicated. |
