The Saudi Power Grid has a propensity for voltage support problems because of the large volume of air-conditioning (induction motor) load connected onto their system. The 380kV SVS system has a dynamic rating of 800MVAr, and it comprises a large capacitive range for dynamic voltage support. July 2009 Over the next few months, the world’s largest utility SVS to date will be commissioned at Riyadh in Saudi Arabia.
