Practical Dynamic Equivalence Method for Provincial Power Grids Based on BPA
摘要
Abstract
The paper studies dynamic equivalence method for external systems and internal systems of provincial power grids.In dynamic equivalence for the external system,on the basis of characteristic of weak AC connection among provincial power grids,it proposes to adopt principles of consistent short-circuit current,voltage and power flow on tie lines for simplified equivalence.In dynamic equivalence for the internal system,in order to break through limitation of power system dynamic equivalent program (PSDEP) connected with BPA,it compares and analyzes two technical lines including dynamic equivalence preprocessing-PSDEP-model transformation and dynamic equivalence preprocessing and generator parameter aggregation-PSDEP by taking parameter aggregation for the excitation system for an example.The analysis results indicate under the condition of high requiremcnt for dynamic equivalence precision,it is nccessary to develop new parameter aggregation program for generators.And this dynamic equivalence method for the provincial power grid can accelerate dynamic equivalence and is adaptive to requirements for high engineering precision.power system planning and operation departments,which means this method is of high practicability.关键词
