电力系统暂态稳定分布式仿真的边界值方法

Boundary Values Methods for Power System Transient Stability Distributed Simulation

中文摘要英文摘要

研究了电力系统暂态稳定分布式仿真的计算效率及提高效率的方法。应用空间并行算法,电力系统分裂为若干子系统,分布式计算的瓶颈是较低的网络通讯速度和完成子系统一个积分步计算边界值的多次通讯迭代。由于边界值收敛特性是影响分布式计算效率的主要因素,对此,文中提出了三种边界值方法,以改善子系统迭代收敛特性。 试验验证,文中提出的方法降低了边界值在子系统间的必要迭代次数,从而降低了积分步计算的通讯频度、提高了分布式计算效率。

his paper studies the efficiency of power system transient stability distributed simulation and the methods to enhance the computation performance. With parallel in space scheme, power system is split into several subsystems. The bottlenecks in distributed computation are the low speed network communication and the mass times of boundary values exchange for subsystem time domain step solution. For that the iterative boundary values convergence property is the key factor to affect the efficiency, three Boundary Values Methods(BVM) are presented to improve the subsystem solution convergence property. With the BVM, the necessary exchanging times of boundary values are reduced, the communication times for one time domain step is shorten and the distributed computation efficiency is improved.
