摘要
在不采取任何修正措施的情况下,电磁暂态仿真计算在开关动作时可能会出现数值振荡现象。目前,线性插值法是消除这种振荡最常用的方法。但是,如果插值法采用的初始数值存在误差,数值震荡可能无法被完全消除。提出一种改进的线性插值法,通过调整计算方法排除误差影响来解决这一问题,并通过仿真对结果进行了验证。
Electromagnetic transient simulation has a risk of numerical oscillation at the same time of switches action when no measure is taken. The linear interpolation method is most widely used to eliminate the numerical oscillation at present. But in the case of error existing in the initial value, the numerical oscillation may not be ehminated completely. We put forward an improved method of linear interpolation by adjusting the calculation method to eliminate the influence of errors to solve this problem, and prove the results through simulation.
