摘要：
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. © 2019, Power System Protection and Control Press.
