  1. The new 150 Mvar, 18 kV SVC at CERN – background, design and commissioning K. Kahle, J Pedersen, CERN T Larsson, M M de Oliveira, ABB

  2. Background • CERN: European Organization for nuclear research (particle accelerators) in Geneva, CH • ABB: Delivery and installation of a new Static Var Compensator • The load: • Particle accelerator Super Proton Synchrotron, SPS • 12-pulse thyristor power converters for accelerator magnets • Heavily pulsating active and reactive power • Sensitive to harmonic distortion

  3. Design • SVC: • 150 Mvar: Thyristor Controlled Reactor, TCR • 130 Mvar: 8 harmonic filters

  4. Commissioning results • Load current: pulsating every 14 seconds from zero to 4500 A • Voltage response: Voltage fluctuations below +/- 0.3 % (0.75 % transiently),14 % without SVC • Harmonic distortion: THD below0.75 %, 20 % without SVC

  5. Conclusions • Excellent performance possible with a classic SVC for sensitive and dynamic loads • It is possible to accurately model the process in computer programs and to predict the system behaviour
