The granted patent (Publication Number: US11881712B2) discloses an arrangement for compensating for voltage dips in a power supply network. The arrangement includes at least one first converter system and a second converter system, both converting between alternating current and direct current. The direct current link circuits of these systems are coupled, with two independent line paths connected to a battery system for compensating for voltage dips. The arrangement is designed to maintain voltage at a critical load by decoupling the power supply network in a fault state and utilizing energy stored in the battery system to compensate for voltage dips.
Furthermore, the patent describes a system comprising the aforementioned arrangement, a first network infeed, and a second network infeed. The first and second network infeeds are connected to first and second distributions via transformers and switches. In different states, the switches control the electrical connection between the network infeeds and distributions. Additionally, the patent details the use of measured values for phase matching before a switch is activated, ensuring efficient operation of the system. The patent also highlights the use of medium-voltage distributions and back-to-back links for electrical connections within the system, enhancing its overall functionality and reliability.
