Current References Limitation Method Considering Voltage and Current Maximums for STATCOMs Providing Simultaneously Reactive Power and Current Harmonics

This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active filter or active impedance functionalities). Being more specific, this proposes general limitation method reduces references STATCOM whenever voltage limit converter is exceeded. In realistic operation scenario, STATCOM’s operator may ask for certain harmonic reference signals, depending actual grid conditions (unbalances harmonics), required exceed their limit. Consequently, proposed protects system from malfunctioning when exceeded damages Hence, first oriented to solely exchanging power. Second, generalized controls as well harmonics. Then, simulation experimental results are provided validate method, under rich variety working conditions. Finally, conceptual carried out confronting it against possible alternatives.
