摘　　要：为解决传统的考虑暂态稳定约束的最优潮流(TSOPF)方法暂态约束条件数量庞大、计算复杂性高等问题,可通过修改Matpower工具包和PSS/E软件,进而实现了一种故障初始时刻考虑暂态约束的TSOPF算法,通过对等效系统初始稳态功角偏差的约束,一般TSOPF方法中数量庞大、复杂的暂态约束条件被简化为数量唯一的稳态约束条件,TSOPF方法的问题规模被降低到与传统最优潮流问题相同的程度。基于IEEE3机9节点系统和10机新英格兰系统的算例,验证了该算法的有效性。In order to solving the problem of transient stability constrained optimal power flow method （TSOPF） that the traditional TSOPF method has large set of transient constraints and high computational complexity, through modifying matpower toolbox and PSS/E software, this paper develops an approach to formulate TSOPF based on single machine equivalent （SIME） method, which considered transient constraints at the initial fault time. By constraining the initial steady state angle deviation of the equivalent system, huge numbers and complex transient constraints in traditional TSOPF methods are reduced to a single steady state constraint. The size of TSOPF problem is reduced to the same as a conventional optimal power flow （OPF） problem. Numerical examples of the IEEE 3 machine 9 bus and 10 machines New England systems are used to demonstrate the validity of the approach.
