"In the past, the voltage was low and unstable. One induction cooker could not be used. When there was a guest, it was very nervous. Now it is no problem to use several induction cookers." Li Zhengfu, a large electricity consumer in Qiong Village, Qiongzhong County, Hainan Province, said that this year's Spring Festival The occupancy rate of this "most beautiful Chinese country" homestay is 100%, and the electricity consumption is normal. Li Zhengfu and other villagers felt that the reliability of power supply in Hainan Power Grid has increased year by year.
According to the 2017 National Electricity Reliability Annual Report, among the 36 provincial power companies in the country, the largest increase in the average power supply reliability rate in 2017 was Hainan Power Grid Corporation, which reached 38.4%, and the ranking increased by 5 points.
Dare to break the question:
Haikou Sanya Central City power outage target "1 hour"
The reduction in the average power outage time of customers is an intuitive manifestation of the improvement of power supply reliability. The dozens of hours of power outages in important areas such as Haikou and Sanya are the hurdles that Hainan Power Grid Company has to overcome in order to speed up its development.
In 2017, under the development goal of China Southern Power Grid Corporation “185611â€, Hainan Power Grid Corporation quickly formulated the “183221†target. The first “1†refers to “the average power outage time of customers in Haikou and Sanya's downtown area is less than one hour in 2020â€.
Dare to challenge high standards and demonstrate the determination and strength of Hainan Power Grid Corporation.
The company quickly researched and issued the "2017 Customer Outage Time Management Improvement Action Plan" and "2017-2020 Corporate Customer Outage Time" 1" hour improvement action plan, focusing on Haikou and Sanya central urban areas, and planning the average customer average. The key measures to improve the blackout time, clear the division of responsibilities, and dynamically track and supervise the implementation.
The “Three-Year Action Plan†of Hainan Power Grid Company, which echoes this, is also in full swing.
In 2017, Hainan Power Grid Corporation invested 5 billion yuan to strengthen the construction of grids, and completed the commissioning of 30 35 kV and above power transmission and transformation projects, with a new substation capacity of 694,000 kVA and a line of 123 km; completed and put into operation more than 4,000 10 For distribution projects of kilovolts and below, 4,702 kilometers of lines of 10 kV and below were added.
“For example, in Haikou, four substations such as the 110 kV Yusha substation were continuously put into operation last year, and the problem of low pass rate of the main network 'N-1' in the central city was gradually solved.†Lu Wenbo, deputy director of the infrastructure department of Haikou Power Supply Bureau, said that 2017 The average power outage time of Haikou customers decreased by 41.44% year-on-year, the second largest decline in the country.
Due to the accumulation of grid construction in 2017 and before, the blackout period caused by the main network factor of Hainan Power Grid has been declining year by year, and many indicators of the distribution network have improved.
The data shows that the transferable power supply rate of Hainan distribution network 10 kV public line has increased from 36% in 2016 to 52.5%, the distribution automation coverage rate has increased from 35% to 50%, and the average customer power outage time has dropped from 43 hours to 26.2 hours. .
Courage to innovate:
Make a good management portfolio
“Power supply reliability is a concentrated expression of the company's comprehensive management level and customer service level.†Lu Qingshan, director of the Biotechnology Department of Hainan Power Grid Corporation, said that it is indispensable to grasp the reliability of power supply, strengthen the grid and strengthen management.
On July 5, 2017, Hainan's first urban power distribution management center was established in Sanya Power Supply Bureau. The distribution management center effectively integrates the superior resources such as power distribution test, live operation, and cable fault handling of each power supply, shortens the troubleshooting time, and realizes emergency elimination without power failure.
“The operation and maintenance mode of the distribution center effectively changed the problem of “collecting and escrow†in the previous mode of power supply coordination, and realized the closed-loop management of defects.†Liu Xinxin, director of the center, said.
This operation and maintenance model has also gradually been implemented in areas such as Haikou. While doing a good job of institutional innovation, Hainan Power Grid Corporation has made a good "three-step chess" and continued to strengthen basic management.
Pay close attention to the comprehensive power outage management of the distribution network. Coordinate various power outage requirements, strictly control the implementation of the plan through interviews, assessments, etc., and strive to reduce the rate of repeated power outages. In 2017, the repeated blackout rate of urban and rural power outages in Hainan decreased by 16,30.99 percentage points respectively.
Vigorously carry out live work. In 2017, the number of distribution and live working operations increased by 452.26% year-on-year, reducing the customer's power outage time by 1.26 hours/household.
Turn on the "UAV" inspection to improve the safety, reliability and efficiency of the transmission line inspection. In the whole year, 1887 sorties of transmission line drones were patrolled, 3,453 bases of patrol poles, and 1,585.75 kilometers of patrol transmission lines.
Starting with the user:
Strive to change from using electricity to using electricity
Knowing the beginning of the journey, the practitioner knows what it is.
"People's electricity industry for the people" is the initial heart of Hainan Power Grid Corporation.
"Last year, the power supply bureau gave us a new line. Now we have almost no power outages and our services are getting more and more intimate. We are very satisfied." Mr. Luo, who lives in Beijing Airlines Apartment, Wuzhishan Road, Longhua District, Haikou City, expressed his gratitude for the work of the Power Supply Bureau.
This is one of the results of the Haikou Power Supply Bureau last year to rectify the power supply card neck problem in the city. In 2017, Hainan Power Grid Company intensively carried out high-temperature power outages to “complaint†the whole staff to reflect, with six bans on customer service, and forced the teams at all levels to take the team tightly and take the initiative to meet the needs of users.
The company cooperated with the local government to conduct electricity safety inspections in 3310 districts throughout the year, with an investigation rate of 96.30%; and cooperated with the government to assist the community to carry out rectification of hidden dangers and improve the safety of power supply on the user side.
At the same time, the public announced the power supply services to benefit the people and the eight major measures, significantly shortening the electricity charging time of more than 30%, eliminating 596 low-voltage Taiwan, and quickly solve a number of economic and social development problems, with true feelings Bright and beautiful Hainan.
In 2018, in order to serve the construction of Hainan Free Trade Zone (Hong Kong), Hainan Power Grid Corporation focused on improving the power supply index and optimized the power business environment.
The company launched the "fourteenth five-year" and medium- and long-term development plans for the smart grid, accelerated the "three-year action plan", further optimized the grid structure, and improved the power supply capacity of the main distribution network; continued to strengthen the comprehensive power outage control, and the power supply bureau established the transmission (with The electric management center will comprehensively promote the medium-voltage intensive management; set up a provincial-level live working center, implement the distribution network drone inspection, release ten service measures for customer service, and strengthen the responsibility transfer and assessment to reduce the customer's power outage time. Strive to reduce the average power outage time in 2018 by 20% year-on-year. In 2019, the average power outage time increased to the top five in the country.
