AN ELECTRIC PLANT WITH CAPACITY TO CHARGE ELECTRIC BATTERIES

摘要

An electric plant with a capacity to charge electric batteries is a plant for transmitting electric power comprising a Voltage Source Converter (1), an alternating voltage network (14) connecting an alternating voltage side of the converter and a direct voltage part (7) connected to the direct voltage side of the converter. The converter (1) has a series connection of switching cells (8) having each at least one energy storing capacitor. Electric batteries may be connected in parallel with said capacitor, and the charging state thereof may be influenced by controlling the switching cells of the Voltage Source Converter through a control arrangement (15).
