摘　　要：随着电网动态行为的复杂化,求取系统稳定极限显得尤为重要。基于多分的思想,提出了适应性多分法的暂态稳定评估策略,利用并行化技术,设计了动态分配的优化并行算法。最后,通过可靠的BPA接口设计,成功地将BPA应用于暂态稳定分析中。华东电网实际系统算例表明,该算法计算速度快,计算结果准确可靠,为暂态稳定分析软件的开发提供了有效的途径。Since the dynamic behaviors of the power system become more and more complicated, it is critical to get the system＇s stability limits. A parallel transient stability assessment strategy which combines the adaptive multi-section technology and the transient energy function theory is proposed, and the BPA was successfully applied to transient stability analysis through reliable BPA interface. The calculation example of East China Power Grid shows the algorithm speedy, accurate, and reliable.
