Coordination of synchronous compensators and converters to improve the commutation failure recovery performance in HVDC systems

Abstract A novel control strategy of synchronous compensators and converters is proposed to increase the ability line commutated converter (LCC) based HVDC systems successfully recover from commutation failures (CFs). The dynamic var support one most important factors, which impact process. Many have been implemented enhance transient voltage stability for improving CF recovery performance. However, traditional automatic regulator (AVR) compensator may not be suitable support, because demand during neglected. In our work, will adaptively adjusted, depending on state converters. Case studies simulations in PSCAD/EMTDC show that can improve performance fault CF.
