Study on Static Voltage Stability Equivalent for Zhanyu Centralized Wind P ower Integrated into P ower Grid

Zhanyu wind power integration project uses a typical central integrated method. With the increasing wind power generators and power outputs, studying the risk is necessary for static voltage stability from Zhanyu centralized outgoing system. It is an important con?straint condition to determine the safety operation boundary. This study is based on typical wind power centralized outgoing transmission system. The paper includes system equivalent study of static voltage stability, the assessment of the key factors which have impact on transmission power at static voltage stability limit and case study of static voltage stability of Zhanyu centralized integration system from building equivalent system. The results provide theoretical and technical support for determining the actual operation safety boundary.
