Voltage Support Studies

Voltage support studies determine the optimum ratings and placement of reactive-power support devices such as shunt capacitors, shunt reactors, adaptive VAR compensators, static VAR compensators, and inverter-based reactors in transmission and distribution systems.

Transmission system studies typically focus on the ratings and performance of reactive-power support devices under normal and contingency operating conditions. Distribution system studies typically involve optimizing the placement of shunt capacitor banks and the ratings and performance of dynamic VAR compensation devices for flicker-producing loads, such as welders and arc furnaces, and large motors.

Voltage-support studies are performed using CYME International’s Power System Analysis Framework-Flow and CYMDIST, PTI’s Power Simulator for Engineering, SKM DAPPER, or the Alternative Transients Program.
