暂态稳定极限耦合的多个输电断面极限功率协调计算
Coordinated Limit Power Calculation of Multi-sections with Transient Stability Limit Coupling
摘要
Abstract
In order to quantitatively assess the interaction between transmission levels and implement automatic calculation of limit power of multi-sections simultaneously,a coordinated limit power calculating method of multi-sections coupled with transient stability limit is proposed.The coupling mechanism is analyzed first,and a coordinated model for the dominant limit power of multi-sections to reach critical stability at the same time is developed.Then a quantitative method for analyzing the influence of simultaneous variation of multi-section transmission power on stability margin is proposed.An iterative algorithm based on the mathematical programming method for solving power increase step size is designed,which can be used for offline or online analysis and real-time monitoring of transmission limit power of multi-sections.The validity of this method is verified by an example of an IEEE 10-unit 39-bus system.关键词
