Online Analysis and Optimal Decision-making of Short-circuit Current in Interconnected Power Grids
摘要
Abstract
The technology of online analysis is an important means to deal with the problem of the excessive short-circuit current and the random fluctuation in an AC/DC power grid.Combining the modeling scope and the real-time data acquisition of a dispatching automation system,the calculation principle of the online short-circuit current and the over-proof criterion are proposed.The multi-objective step-by-step optimization decision-making of the day-ahead and the real-time short-circuit currents is proposed,which improves the adaptability of the short-circuit current optimization strategies to the time-varying and complexity of the power grid.The functional architecture of the online short-circuit current analysis and optimization control system is constructed.By integrating the functions of the dispatching and the station terminals,the reliable closed-loop control of the short-circuit current is achieved.This method achieves the application of the refined analysis,the comprehensive optimization decision and the precise control of the short-circuit current in the actual power grid.The effectiveness and practicability of this method are verified by the analysis of the running results of the short-circuit current analysis and optimization control system in an actual power grid.关键词
