HVDC station is used to connect two or more synchronous AC power systems with different frequencies. It allows to trade electricity between separate synchronous areas and also increases energy security, reliability and efficiency. High voltage equipment for filtering AC current harmonics on the inverter side of HVDC station. The vertical cilynders on pillows are coils that acts as passive filters for ac current. The equipment inside the facilities connects ac part and dc part of the inverter. Electrical equipment in the closed substation looks futuristic.
