论文摘要
本文提出了考虑二阶导数的频率响应优化的集成剂。基于提出的数值集成符,以及其他考虑二阶导数的基础,本文提出了一种新型的功率系统瞬态仿真方案。所提出的仿真方案不是使用唯一的数值集成器,而是根据差分状态变量的主要频率组件选择适当的模拟方案。通过提出的仿真方案,通过使用大型步骤大小而不会牺牲准确性,可以提高计算效率。数值案例研究证明了模拟方案的有效性和效率。
Frequency response optimized integrators considering second order derivative are proposed in this paper. Based on the proposed numerical integrators, and others which also consider second order derivative, this paper puts forward a novel power system transient simulation scheme. Instead of using a unique numerical integrator, the proposed simulation scheme chooses proper ones according to the dominant frequency component of the differential state variables. With the proposed simulation scheme, computational efficiency is improved by using large step sizes without sacrificing accuracy. Numerical case studies demonstrate the validity and efficiency of the simulation scheme.
