Abstract: With the development of automation, digitalization and technology, the electrical industry's demand for station-level operation and control is transforming from multi-person duty to unattended duty.In order to achieve unmanned operation and monitoring at the field level, data collection, data demonstration, remote monitoring of equipment, and AI early warning are necessary.To achieve the above functions, this paper proposes the integrated architecture of a domestic autonomous decentralized control system(DCS) and cloud platform.The DCS system uploads the collected data to the cloud platform.The cloud platform processes, stores and displays the received DCS system data and feeds back to the DCS system for real-time regulation of the entire station.Under the integrated architecture of DCS system and cloud platform, station level unattended, remote monitoring and equipment remote control can be realized.
