static VAR compensators 的滑模控制论文-The paper deals with the　design　and evaluation　of a

variable-structure　stabilizer for static VAR compensators

using a sliding mode control technique.　The static VAR

system plays an important role as a stability aid for small

and large signal transient disturbances in an interconnected

power system. A systematic procedure for　selection　of

switching hyperplanes in the design of variable-structure

controllers is developed by using a geometric approach

known as projector theory.　The sliding　mode control of

static VAR controllers hnproves the transient response of

the power system and provides significant damping to the

electromechanical oscillations of the synchronous genera-

tor. Computer simulation results for a typical power system

shows the effectiveness of a VSS static VAR stabilizer.
