| 摘要: |
| 目前国内常规的10 kV变电站中高压开关设备日常运行、操作和维修基本上依靠人工来完成，不仅会增加电气工人劳动强度，而且缺乏对高压开关设备故障预判的前瞻性。针对这种人工运维模式带来的问题，结合目前国内常规的变电站10 kV高压开关设备的工作流程和控制要求，采用嵌入式工控机配套组态软件作为上位主控设备，智能监控单元、综合保护装置等组成下位设备。上下位设备之间通过网线采用IEC61850中的GOOSE通信协议连接，构成嵌入式工控机+智能监控单元+综保装置的小型DCS集散控制系统。该系统采用温升实时、断路器状态在线监测技术和智能操控、状态视频监视技术，在满足高压开关设备日常运维需要的同时，很大程度上提高了供配电网络的智能性、可靠性和安全性。 |

| Abstract: |
| At present, daily operation and maintenance of high voltage switchgear basically rely on artificialness in domestic conventional 10 kV transformer substation, which not only increases electrical workers labor intensity, but also is the lack of forward-looking pre-judgment of the high voltage switchgear fault. Aiming at the problems caused by this artificial operation mode, combining the workflow and control request of 10 kV high voltage switchgear, this paper chooses embedded industrial PC as supervisory computer and takes intelligent monitoring unit, power comprehensive protection device as control computer. The supervisory computer and control computer are connected via the industrial network by adopting the GOOSE communication protocol of IEC61850, forming embedded IPC+ intelligent monitoring unit + power comprehensive protection device small-scale Distributed Control System (DCS). The system adopts technologies of temperature rise monitoring, vacuum circuit breaker state monitoring, and state video monitoring. It not only accomplishes the need of daily operation and maintenance of high voltage switchgear, but also improves the intelligence, reliability and safety of power distribution network to a great extent.
