摘　　要：考虑分布式发电接入,提出了一种改进的基于潮流解存在性的配电网电压稳定判据。结合现有的电压稳定性指标和分布式发电的特点,在分布式发电的接入点及其上游节点处采集电压、电流、功率等信息,根据改进的电压稳定性判据实时监测配网的电压稳定性,并建立相应的仿真模型对该判据有效性进行仿真验证,理论分析和模拟仿真都验证了该改进判据的有效性。Considering the distributed power generation,an improved voltage stability criterion for distribution,network based on the solutions existence of power flow is proposed.The collection of voltage,current,power and other information are cam（ed out in the distributed power generation access point and its upstream node. According to, the improved voltage stability criterion, the voltage stability of the distribution network is monitored in real time, and the corresponding simulation model is established to verify the validity of the criterion.The theoretical and simulation tests verify the effectiveness of the improved criterion.
