Filter reactor,or called DC flat wave reactor,is applied to DC side of converter,the flow of a reactor is a DC current with an AC component. It keeps the AC component of DC currrent in one kind of range. It is applied to the DC side of the parallel converter to reduce the intermittent limit and limit the circulation in the circulation line,is applied to DC fast cut off fault current limiting current rise rate.It is used in the DC flat wave of the current, voltage type inverter in the middle,which can be used for the rectification of the power flat wave to eliminate the ripple. The flat wave reactor is used in the DC circuit after rectification. The pulse wave number of the rectifier circuit is always limited, and there is always a ripple in the output of the whole direct voltage.And the ripple is harmful, need to be suppressed by the flat wave reactor DC transmission are equipped with flat wave reactor, is close to the ideal output DC. flat wave reactor and DC filter are constitute DC harmonic filter circuit of high voltage DC DC converter station together.flat wave reactor is tandem connecting between DC output and DC circuit of each converters,is one of the important equipment in HVDC converter station. the flat wave reactor and DC filter constitute the DC T type harmonic filter network together,reduce the AC pulse component and filter part of harmonic, reduce the interference of DC line to communication and avoid harmonics to influence adkust instability.
