摘　　要：提出一种传输线瞬态响应的时域分析方法。该方法对电报方程在时域内差分离散,在建立对空间的一阶微分方程组后,采用精细积分法,可获得传输线瞬态响应。这是一种时域内的半解析数值计算方法,具有方法简单、计算精度高等优点,能够有效地分析具有非线性负载的有损耦合传输线瞬态响应问题,也可以用于输电线路的瞬态分析及故障测距。In this paper,a new time domain method is presented to analyze the transient response of transmission lines. The telegraph equations are discreted in time domain, a first order differential equation with respect to space is obtained, then by using the precise integration method,the transient response of the transmission lines can be obtained. This is a semi- analyric numerical method,it is simple,accurate and efficient,and can be used to analyzed the transient response of the lossy coupled transmission lines with nonlinear terminals efficiently. It also can be used to analyze transient response of power transmission lines and detect the fault location.
