Advanced Controls and Coordination of the Road Runner and China Draw SVCs

Due to rapid load growth in SE New Mexico, a Southwest Power Pool (SPP) transmission plan was developed through the High Priority Incremental Load Study Process (HPILS). The uncertain future and timing of both additional load growth and generation changes made dynamic shunt compensation an ideal complement to the development plan. When weak network conditions are combined with a significant penetration of induction motor load at fault clearing, the network is prone to either overvoltage or Fault Induced Delayed Voltage Recovery (FIDVR). Advanced control functions and appropriate component ratings are necessary to not only maintain transmission operation within criteria limits, but also provide an optimal dynamic response over the expected range of network configurations. Advanced control includes coordination that significantly improves the performance of supplemental control functions when electrical interaction between nearby installations exists.
