摘要
可调谐的隐式Taylor级数暂态稳定算法是在隐式Taylor级数法的基础上,通过合理设置参数位置及其大小得到的一种具有A稳定性和高精度特点的优秀暂态稳定分析算法。通过分析故障时发电机功角曲线的变化规律和定义曲线变化因子,并根据曲线变化因子不断调整步长,提出一种新的变步长方法,在满足计算精度的条件下,可进一步提高算法的计算效益。
On the basis of Taylor series method, implicit Taylor series method for simulation of power system transient ac- quires a transient stability calculating method with A stability and high efficiency by means of setting reasonable parameter position and size. By analyzing variation law of load angle curve under circumstances of generator failures and defining fac- tors of curve variation and in accordance to factors of curve variation, the step is continuously adjusted and a new variable step method is brought forward, which can further improve calculation efficiency, and in the mean time realize calculation accuracy.
