| Abstract |
This paper presents a new real-time simulator built for engineering studies of thyristor systems in power transmission applications. Studies of HVDC converter and SVC performance characteristics, and the dynamic interaction with the HVAC system are the main uses of this simulator. The power system is modelled at a very low power scale. All electrical components (transformers, lines, filters, valves and machines) are built from analog electronic circuits with programmable adjustment of the main parameters. An intensive test campaign bas been carried out to investigate the compatibility between models and the influence of operational amplifier performance. Stability, bandwidth, losses and offset have been characterized. The simulator control system (data acquisition system, sequence controller and configuration designer) bas been paid special attention at the design stage to achieve high flexibility and operating performance. |
