AI Technical Summary
Existing transient disturbance control equipment has failed to achieve multi-mode active capacity collaborative optimization and lacks sufficient integration, which makes the distribution network prone to problems such as overvoltage, equipment burnout and phase-to-phase short circuits during transient disturbances.
Design an intensive transient disturbance control circuit, including a three-phase bridge arm unit, a common DC side unit, and a zero-sequence bridge arm unit. The circuit generates current through coordinated operation to offset the zero-sequence component of the fault, adaptively determines the three-phase reactive power compensation current, and provides common DC voltage support, thus simplifying the circuit topology.
It effectively suppresses zero-sequence disturbances in the distribution network, reduces voltage deviation and power fluctuations, lowers equipment hardware costs and size, improves circuit stability and operating condition adaptability, and achieves real-time load balancing.
