UHV DC Converter Station Equipment Monitoring Scheme Based On Panoramic Data System

With the promotion of the global energy Internet,special high-voltage AC,DC rapid development,the national power grid into the era of uhv.Compared with the conventional substation uhvdcconverter station operation equipment number,corresponding to the staff of the daily maintenance of DC converter station maintenance work to increase the difficulty.However,the current Jiaodong high voltage electrical equipment in DC converter station maintenance work mainly adopts the traditional preventive maintenance and inspection methods,and combined with the transformer online monitoring device and monitoring system of single,the maintenance mode of the safe operation of the equipment plays a supervisory role,but from the long-term practice found that regular blackouts offline test in preventing power equipment accidents has its limitations and shortcomings,charged inspection methods while being in the charged state,but a larger workload,the detection cycle is relatively long.At this stage,the smart substation,only to achieve the data channel of optical fiber,digital,does not solve the online analysis of the essence of decision-making and collaborative interaction and other advanced features.Therefore it needs innovation of DC converter station monitoring system,intelligent monitoring of the panoramic data.To solve the above problems,this paper carried out innovative design in the original monitoring system,put forward the scheme of uhvdcconverterstation equipment monitoring system based on panoramic data,intelligent monitoring system can real-time panoramic data all-weather full line monitoring,not only monitoring the main transformer,converter transformer,GIS,HGIS and other key equipment,and the use of radio frequency and UV detection technology advanced,the important equipment of DC field,the valve hall such as field to achieve all-round monitoring,avoid blind spot monitoring.The scheme of three-dimensional panoramic interface,3D modeling of the station equipment and important area,fully realize its visualization,monitoring methods,monitoring method based on a variety of equipment,fully reflect the high voltage equipment in steady state and transient and dynamic data and equipment operation status and image data.Through standardized communication interface,unified standard and unified modeling,realize the comprehensive digital substation.UHV DC converter station equipment monitoring system based on panoramic data scheme provides an efficient and innovative solutions for the operation and maintenance work of DC converter station equipment.Through a comprehensive analysis of thesubstation equipment monitoring data and summary,find fault operation machine development rule of DC converter of high voltage equipment,reduce maintenance resources of unnecessary investment,will be used in the maintenance resources must be checked on the device,greatly reduced maintenance cost,solve the existing problems of the periodic maintenance mode.Can effectively improve the working efficiency of equipment maintenance and inspection quality,reduce the labor intensity of manual detection and work risk,improve the production efficiency of the operation and maintenance of electric power equipment to enhance the comprehensive management level,enhance the HVDC operation safety and automation,intelligent level.
