Da Nang electrician assisting in handling a household's electrical leakage
Previously, short-circuit cases were detected only after each monthly power recording period when Electricity of Vietnam conducted a review of the list of customers with a sudden increase in output at 30% or more. From this very fact, Da Nang PC has developed the software "Analysis of real-time abnormal power output warning from telemetry" based on daily analysis results of 4 groups of cases: "surge", "sharp decrease”, “normal”, “not in use” with visual graphs, helping users identify the possibility of short-circuiting before any actual checking.
In 2021, in Da Nang city alone, 128 cases of short-circuiting and leakage have been detected with many causes such as wires touching corrugated-iron roofs, fences, water tanks, leaking wall wires, touching iron beams on power poles, etc. As a result, the performance has contributed to reducing the cost of electricity paid by customers, preventing the risk of electrical accidents among the people. Inquiries from customers via the hotline 19001909 about meter readings have also decreased significantly compared to that in 2020.
From the efficiency gained for the whole Da Nang city, from April 2021, the Central Power Corporation (EVNCPC) has replicated the application in 13 power companies in the Central - Central Highlands region; at the same time, developed a system "Monitoring abnormal power output" – a web version at: https://gssldien.cpc.vn. In May 2021, this application was deployed in EVN, and up to now, it has been integrated into the program of the Customer Management Information System (CMIS).
The application "Analysis of abnormal power output warnings in real-time from telemetry" was researched by a group of authors from PC Da Nang including Huynh Thao Nguyen (manager); Le Hong Cuong, Vo Hoa (co-manager); Phan Quang Tu, Bui Van Minh, Huynh Van Tien (members). The application won the third prize - Vietnam Science and Technology Innovation Award - VIFOTEC 2020 of the Vietnam Union of Science and Technology Associations (VUSTA); Vietnam Golden Book of Creativity 2021 of the Standing Board of the Central Committee of the Vietnam Fatherland Front.
