"Double speed" repair!The power supply department spent the "peak moment" in the "zero perception" method

The Yangtze River Daily Da Wuhan Client August 20th News At 6:40 am, the main carrier of the 220 kV Erfei Mountain Transformer Power Station, which mainly carries the East Power supply of Wuhan Optical Valley, has completed the main transformer with a power supply capacity of 180,000 kV. Emergency repair and return to normal operation after 1 hour.

Since the beginning of the summer, the continuous high temperature has brought a huge test to the power guarantee of Wuhan area. The State Grid Wuhan Power Supply Company has made multiple measures to ensure the city's electricity consumption.

"The temperature of the main transformer of the Erfei Mountain Transformer Power Station is too high, and it must be repaired as soon as possible to eliminate the defects!" At about 4 pm on August 16th, in the contact group of the operation and inspection department of the Wuhan power supply company of the State Grid, the information of the special patrol players allowed Everyone was nervous.

It turned out that all equipment of the 220 kV Erfei Mountain substation, which is mainly responsible for the supply of electricity supplies in the East of Optics Valley, all the equipment running at full load in the near future. One of the main transformers with a power supply capacity of 180,000 kV of the station was insured on the same day. The temperature of the tour shows too much temperature.

Soon, the State Grid Wuhan Power Supply Company launched a cooperative processing model of regional power preservation, transfer load, comprehensive repair, and user visits, and strive to strive to complete the repair in the shortest time in the shortest time.

"Optics Valley East District not only has 200,000 households and industrial and commercial users, but also important industrial enterprises such as Foxconn and Huawei. The Transportation Inspection Department is responsible for Liu Yuan.

Unlike other 220 kV power stations, there are multiple "brothers stations" in the surrounding area to form a line support and contact. There are only one line exit of 220 kV Erfei Mountain Transformation Power Station. This has formed a pressure on the surrounding 220 kV Temple Mountain transformation station that can share the power load.

"The smooth transfer of power load is an important condition for winning the time of repair and improving the efficiency of repair." Liang Jinyuan, the head of the scheduling method of the State Grid Wuhan Power Supply Company, described to reporters the important mode of the power load of several substations: finding the peripheral load is relatively the most relativelystable, the most relative to the surrounding load is relativelystable. There is a 220 kV Guanshan transformation station with a transfer space. First, the load of the 220 kV brilliant substation nearby to the Guanshan transformation station, and then the electric load of the Miaoshan transformation station is transferred to the splendid power station. Finally The overloaded power load was transferred to the Miaoshan transformation station, and eventually formed a dynamic balance of power supply load in the entire East Lake High -tech Zone, winning a valuable time for the repair of Erfei Mountain Transformation Power Station.

At the same time as the measures such as electricity and load load are parallel, the repair team also conducts special vehicle parking and repair personnel exercises. Finally, after the official construction starts at 0:32 on August 17, it will be completed in just 5 hours in just 5 hours. The repair was shortened by more than half compared with the conventional 12 hours.

At 7:40 am on August 17, after a series of power delivery tests ensured safety, the main transformer of the fever failure of Erfei Mountain was officially resumed. As an important unit of beneficiaries, Foxconn in the area also restored the normal production of the entire industrial park.

It turned out that Foxconn Industrial Park's production and lifestyle all came from the supply of Erfei Mountain Transformation Power Station. After the power supply patrol personnel found that the main transformer defect, they communicated with Foxconn in synchronization to reduce the power load of the industrial park from 46,000 kilowatts to 5,000 kilowatts to ensure the normal living electricity of 17,800 people in the park.

According to incomplete estimates, the power supply department has reduced the entire repair time from 12 hours to 5 hours, allowing Foxconn to start normal production in advance, and the more output value created here may reach millions of yuan. On August 18, the relevant person in charge of the company also specially sent a banner to the State Grid Wuhan power supply company to thank the night of the night.

It is after such a multi -party cooperation that under the power preservation and repair operation of the thunderbolt of the power supply department, there are 200,000 households and industrial and commercial users in the entire Optics Valley East area, and more than 600,000 people will be this At night, through the "zero perception", the "peak moment" was repaired by the substation, and it was imaginative.

Power supply employees are fighting at high temperatures on the front line

Since its peak summer this year, the State Grid Wuhan Power Supply Company has used intelligent equipment such as remote intelligent inspections, drones, and mobile inspections to carry out three -dimensional inspections, timely discover and deal with various types of defects, and carry out a total of 3457 inspections of 3457 times. , Carry out 5,132 infrared temperature measurement, an important cross -measurement of 302 times.

State Grid Wuhan Power Supply Company resolutely adheres to the bottom line of power supply and risk prevention, scientifically arranges the operation of power grids, strengthens the flexible and accurate deployment of the grid load, and fully guarantee the smooth and orderly power supply. In order to protect the coolness of Wanjia, the power supply employees fought on the front line with high temperature and heat. Since the beginning of the summer, the State Grid Wuhan Power Supply Company has dispatched a total of 1,5372 person -times, and the vehicle is 2634 units/time to carry out power guarantee work.

At present, Wuhan is experiencing high temperature weather, the entire society has increased sharply, and the power supply pressure has been continuously improved.According to the State Grid Wuhan Power Supply Company, it will resolutely resisness the responsibility of the power protection of power, effectively protect the power supply of various measures, deal with various types of emergencies in a timely manner, fully ensure the safe operation of the power grid, and make every effort to ensure the normal and stable of the city in the city.Electricity.(Changjiang Daily reporter Liang Shuang correspondent Wang Xin Wu Bin)
