Implementing the 2021 theme of digital transformation of the Electricity of Vietnam and the Northern Power Corporation, Hai Phong Power One Member Company Limited (PC) has promoted the application of science and technology in all fields. manage and operate the power system, including the conversion of substations (TBAs) from manned to unmanned.
With the goal of converting all substations to the unmanned substation model, Hai Phong PC is actively implementing digitization in the field of power system operation management. Technical management and grid operation management activities have been carried out on software systems such as power system operation reporting system, technical management system, data collection system. metering on the power grid, power failure information management system (OMS), general reporting on 110kV grid operation, control, monitoring and SCADA/DMS data collection system.
At the Hai Phong remote control center, the basic features of the SCADA/DMS central software system have been fully exploited such as: managing the grid information model including managing all the main data of the network. control center, edit or create new single-strand diagram structure of TBA, color grid, edit graphics, batch data import, declare and map signals of equipment at TBA and devices on the distribution grid (Recloser/LBS/FI), set up audio and event alarms, simulate the status of equipment on the grid, store, analyze and exploit historical data on the system. In addition, Hai Phong remote control center is gradually deploying and building a smart grid subsystem (DMS) with grid computing applications such as: load reporting, distribution estimation, capacity flow calculation, fault locating and isolation, etc. 
Operations Engineer at Remote Control Center The conversion of manned 110kV substations into 110kV unmanned substations helps to promote the application of digital technology, innovate and improve the management and operation process of the power system. As of May 27, 2021, the Company has 07/24 110kV substations operating with unmanned criteria, 09/24 110kV substations operating in remote operation mode with on-site supervision. 70/90 devices (Recloser/LBS) on medium voltage grid are connected and controlled remotely from Hai Phong Remote Control Center. With 99% success rate of remote manipulation ( As planned in 2021 put 110kV and . substations control devices Recloser/LBS rest perform remote control) contributed to improving labor productivity, reducing system operating costs, improving reliability of power supply and ensuring safe grid operation. In early 2021, Hai Phong PC applied digital technology to develop software for automatic ground fault handling. The software is currently being put into trial operation. Automatic ground fault handling software is highly applicable, helping to automate the current ground fault handling process, reducing the time to find fault points, and minimizing the number of customers. affected by incidents, thereby reducing power supply reliability indicators SAIDI, SAIFI, MAIFI, improving power quality, avoiding confusion that may occur due to subjective factors of users caused by operation. Automating the troubleshooting process enhances worker productivity by reducing the dependence of the troubleshooting process on the operator. The software is a premise for the development and expansion of advanced applications in the process of modernizing the distribution grid towards operating the smart grid in Hai Phong city. With efforts and determination to realize the goal of digital transformation, Hai Phong PC in particular and the Power industry in general are gradually implementing innovation, creativity, digital technology integration and production management model. business, technical management, making an important contribution to the digital transformation roadmap of the Electricity industry in order to improve the quality of customer service, to meet the needs of socio-economic development of Hai Phong city.
