Abstract

To solve the problem of strong asymmetry and time-varying harmonic voltage in active distribution networks, which makes it difficult to suppress residual harmonic currents in grounding faults, a tracking control method for active harmonic arc suppression in active distribution networks is proposed, considering the imbalance and fluctuation of harmonic voltage. By analyzing the formation mechanism of harmonic voltage in the distribution network and combining it with measured data, the imbalance characteristics of three-phase harmonic voltage in the distribution network have been confirmed. On this basis, a harmonic fault current component expression considering harmonic voltage imbalance is established, and it is demonstrated that the voltage imbalance component is the main component of harmonic fault current. In order to eliminate the influence of voltage imbalance on harmonic arc suppression, an active flexible arc suppression method considering harmonic voltage imbalance is proposed, which can achieve good compensation effects for low and high resistance grounding faults. At the same time, considering the changes in fault current caused by the time-varying harmonic voltage, a dynamic tracking control strategy for controlling arc suppression current injection is proposed to achieve real-time tracking of fault development changes and dynamic suppression of fault current. The simulation and experimental results show that the proposed method can effectively suppress harmonic fault currents in active distribution networks and achieve reliable arc suppression.
