- In this paper, an analysis is given on open-loop control of the transmitted active power using a TCSC in a power transmission line, and its sensitivity to parameter variations is investigated. The performance of the closed-loop TCSC with PID and
Smith-chart
- 史密夫图表(Smith chart，又称史密斯圆图)是在反射系散平面上标绘有归一化输入阻抗（或导纳）等值圆族的计算图。是一款用于电机与电子工程学的图表，主要用于传输线的阻抗匹配上。该图由三个圆系构成，用以在传输线和某些波导问题中利用图解法求解，以避免繁琐的运算。一条传输线(transmission line)的电阻抗力(impedance)会随其长度而改变，要设计一套匹配(matching)的线路，需要通过不少繁复的计算程序，史密夫图表的特点便是省略一些计算程序。-Smith chart
