Generally, the Unified Power Stream Controller (UPFC) was controlled by the conventional corresponding integrative (PI) controller, however PI controller will make the power framework work in a slender range, which identified with the UPFC establishment area, control framework working arrange, working states and the planning of UPFC controller.

Particularly, when the last power framework relentless state variated, the framework ought to working in another enduring state, and there is a solid coupling zone between these two consistent states, PI controller will scanning for the new unfaltering state around the previous one repeatly, and can not acquire another enduring state.

So that, utilizing PI control for UPFC controller will debilitate the power stream control capacity incomprehensibly. Subsequent to showing the customary PI controller, this paper proposition another controller for UPFC in light of single never cell-versatile PID control calculation, then, advanced flag processors (DSP) are utilized to execute the controller, MATLAB/SIMULINK and PSCAD/EMTDC are utilized to demonstrate the single nerve cell-versatile PID controller and UPFC framework.

For looking at the control impacts controlled by single nerve cell-versatile PID controller and customary PI controller individually, the three-stage establishing and transmission control swaying reproductions are made.
