SERIES COMPENSATION DEVICE

WIPO Patent Application WO/2018/033058

A1

A series compensation device, including at least two voltage source converters, at least two three-phase transformers and at least one three-phase reactor. The voltage source converters are connected in series to a multi-circuit line by means of the three-phase transformers, and alternating-current sides of various voltage source converters are connected to each other by means of the three-phase reactor, so that the function of equally dividing a system power flow by a plurality of converters is realized. The device can be independently installed in a power transmission system to be used as a static synchronous series compensator, and can also be used as a component of a unified power flow controller, a convertible static compensator, an interline power flow controller and a unified power quality conditioner to be connected to a power transmission system device in series. The device can save the capacity of a converter, improve the application efficiency of the series compensation device, and reduce the cost and the floor area.
