Modeling and simulation of a Kalman filter based control scheme for an AC/DC power system

Restructuring And Innovating Of Power System Analysis And Power Electronics Courses At The University Of Northern Iowa

“…It is the recommendation of the author that investigators performing any future work in this topic try to apply more interdisciplinary collaborations into power systems and power electronics studies. In another study, the author has shown that the Kalman filtering, a digital filtering method in discrete-time, applied to the HVDC converter control system discussed in Case 2 of this paper has improved the overall AC/DC power system performance by reducing the voltage and current transients [15][16] . The case studies discussed in this paper have shown that PSCAD/EMTDC will have a great impact to new power technology curriculum at the University of Northern Iowa.…”

“…This case study is based on investigation of ac/dc power system interactions including ac/dc and dc/ac converter operations for a proposed HVDC transmission line from Wyoming to California as shown in Figure 4 [15][16] . There are three types of faults that affect any ac/dc system: (i) faults on the dc line; (ii) faults on the ac system including ac lines; and (iii) faults at the converter stations.…”

“…The converter controls play a significant role for the transient period of the faults in the dc systems, while circuit breakers equipped with measurement and protection relays detect and try to remove the faults in the ac systems. In addition to these fault clearing actions, tap changers of converter transformers also help the steady-state stability to be preserved in a longer time period following a disturbance [15][16][17] .…”
