摘要

在运换流站加装调相机后

因直流控保系统与DCS监控的差异性与独立性

存在相关断路器、隔离开关控制问题。为实现换流站监控一体化

结合调相机不同的入网接线方式

从并网断路器是否独立及DCS是否主导控制两点进行分析研究

提出了换流站加装调相机后新DCS和原直流控保系统对新增断路器及隔离开关的联合控制方案。保证并提高了直流控保系统及DCS的自动化程度

提升运维效率。该方案使得同站不同系统控制界面清晰

并经过现场验证

为调相机无缝加装进入换流站提供了有力的支撑。

Abstract

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.
