Voltage profile management in restructured power system using STATCOM

One of the major aims of system operator is to maintain system parameters within feasible operational margin. During certain period of time in a day-load changes very rapidly, especially when it tends to increase, a generalized voltage decrement and stressed conditions for reactive power sources occurs. Maintaining Voltage profile under varying load conditions is need of today under unpredictable load scenario. The work embedded highlights expediency of STATCOM for improving voltage profile of power system under perturbations while providing necessary reactive power support. Performance evaluation is supported by simulation results on WSCC 3-generator 9-bus system under different loading conditions using MATLAB based software tool PSAT.
