This paper addresses the small-signal stability and control problems associated with a long distance voltage supported AC transmission system. Linear techniques are used for the control design of multiple static VAR compensators along the transmission system. Different voltage control strategies are investigated and additional stabilizing signals are designed using frequency response techniques. A new centralized control strategy is proposed and its performance is shown to be superior to the traditional individual bus voltage control. Linear time responses to step disturbances are included to illustrate the performances of the different control strategies investigated.
