The control issue of related circuit breaker and disconnector is existed due to both difference and independence of DC protection system and DCS monitoring after adding condenser for converter station.For achieving integration of monitoring at converter station
the joint control proposal of the newly added circuit breaker and disconnector by the new DCS and original DC control & protection system after addition of condenser of converter station is proposed in accordance with different grid-connected modes and in accordance with analysis of such two points as whether the grid-connected circuit breaker is independent and whether the DCS dominates the control.The automation degree of DC control and protection system and DCS is assured and improved
the operation and maintenance efficiency are improved.This proposal makes the control interface of different systems in the same station clear and
throughout site verification
provides a strong support for the seamless installation of the condenser into the converter station.
