Power supply personnel conduct routine patrol on substation equipment.In The first lunar month, In Shuozhou, Shanxi Province, the wind blows cold outside Yanmenguan.Guo Dongqing and Zhang Jinwen wrapped themselves up, took a thermometer and a record book into yanmenguan converter station, substation equipment for a routine patrol.The cold wind turned their ears and even their faces red, and their lashes and eyebrows were frosted with great masses of white breath.As watchmen, guardians of power, they spent a special Spring Festival here.Yanhuai direct current is one of the 12 key transmission channels in the National Air Pollution Prevention and Control Action Plan. The project starts from Shuozhou, Shanxi Province, and ends in Huai ‘an, Jiangsu Province. It is responsible for supplying power to east China.During the Spring Festival, the power demand in East China gradually increases, and the daily power of YANhuai DC also increases, posing a challenge to the operation of the equipment.Yanmenguan converter station as the starting point of yanhuai DC project, in order to ensure reliable power supply during the Spring Festival, start the cold and freezing response plan, strengthen the station equipment professional patrol, live monitoring, infrared temperature measurement.”500 kV fourth group OF AC filter power cabinet temperature is too low.”In the intercom suddenly came the voice of the background duty, duty personnel immediately started to check the adjustment.The staff on duty of the station can find the defects of the equipment in time through the self-developed equipment operating state perception and intelligent fault diagnosis system.According to Zhang jinwen, the intelligent diagnostic system can analyze and compare more than 5,100 data sent to the background.”Through the status curve generated by the background data, we can find equipment defects in the first time, saving the time of field inspection and improving the quality and efficiency of operation and maintenance.”On the afternoon of New Year’s Eve, feng Lijun, the stationmaster on duty, organized all the team members to carry out the accident expectation of dc line failure under bad weather.”No matter when it happens, we can’t completely let our guard down because it doesn’t happen at a particular time.”The chief of duty then arranged the work, “The Spring Festival duty we shoulder a heavy responsibility, must always control the operation of the equipment, to ensure the smooth operation during the festival.”Since it came into operation in 2017, yanmenguan Converter Station has delivered more than 110 billion kilowatt-hours of electricity.
