The first summer is still clear and the grass is still. Since The beginning of June, the temperature of Tianjin has continued to rise, and the power load has been increasing. State Grid Tianjin Electric Power company has been working with the attitude of “always worried” to ensure safety and power supply, prevent floods and major risks, and firmly guard the “green mountain” of electricity to ensure reliable electricity consumption for production and life of the whole society.
Reliable electricity, ensure residents cool summer
During the high temperature in summer, State Grid Tianjin Electric Power company pays equal attention to the development of power grid and the safety of power supply, and guarantees residents a cool summer with strong power supply.
Not long ago, state Grid Tianjin Chengnan Company staff are in hexi Baiyunli community for transformer capacity. The company through big data analysis, found that baiyunli community load increased year by year, transformer capacity will soon be unable to adapt to the future for a period of time electricity demand. “In order to improve the quality and reliability of power supply, we have carried out transformer replacement work to increase the power supply capacity to 126% of the original, so that residents can enjoy the ‘fresh wind’ and ‘safe electricity’.” Site work director Liu Chang introduced.
After thorough on-site investigation, the staff analyzed and determined the backup power supply, accurately formulated the optimal replacement plan, and finally completed the replacement of two transformers in the community in the form of no power outage operation, so as to ensure the “no perception” of residents during the operation.
Power security is not just about capacity expansion. In the buffer zone of Tianjin Qilihai Wetland with blue sky and white clouds and ripples, a 110kV substation stands on the endless reed lake. The staff of the control center of State Grid Tianjin Ninghe Company are checking the operation of the newly put into operation equipment in the substation.
It is understood that qilihai Substation is the most important power supply support for surrounding enterprises and residents. Due to the gradual aging of cables and other equipment, it is necessary to carry out comprehensive equipment renovation projects. In the process of construction, problems such as narrow space of secondary equipment area, difficulty in dismantling old equipment and difficulty in laying cables need to be solved. Moreover, the simultaneous operation of multiple sites and cross-work of multiple types also bring great challenges to security control.
In this regard, Ninghe company implements the responsibility of the equipment owner, carries out detailed risk analysis and advance deduction for each link, reduces all kinds of construction risks, and ensures that the risk control in the whole construction process is in place. Finally, the transformation task was successfully completed 7 days ahead of schedule, which laid a solid foundation for the reliable supply of electricity and the safe and stable operation of power grid in qilihai region in summer.
State Grid Tianjin Electric Power has always taken power supply guarantee as an important task of people’s livelihood, adhered to the high sense of responsibility and mission, comprehensively accelerated the construction of power grid summer project, and firmly established the defense line of summer power consumption safety.
Prepare for a rainy day, build a strong power “flood barrier”
Summer flood control is related to the overall situation, there is no room for error. In the face of the severe and complex situation of flood control work, State Grid Tianjin Electric Power Co., Ltd. takes on the responsibility of summer flood control as a central enterprise.
“The lines, transformers, low-voltage switchboards and motors are all operating normally.” Recently, the staff of State Grid Tianjin Electric Power Jinghai Company recorded the operation of power equipment one by one at the Dabao Pumping station of Duliu River, and carried out a comprehensive inspection of the equipment status. At the same time, the government and enterprises jointly carried out flood control drills, laying a solid foundation for building a safety defense line in the flood season.
The Jianhe river runs eastward, gathering the huan, Qi, Zhang, Fuming and other rivers with abundant water. The water trend of the jianhe river has always been unpredictable during the flood period. “Since the beginning of summer, Jinghai company has taken safe flood control as an important task. The sea of tranquility company deputy chief engineer Dong Hua strong, said the sea of tranquility company actively communicate with the office of the district flood control, water conservancy department, focus on water, all of the pumping station, sluice gate and drainage culvert thorough examination, familiar with the power lines, equipment, and the real-time monitoring and hidden perils in safety, ensure safe and reliable electricity supply during rainy season.
In line with the principle of practicality, effectiveness and strong operability, Jinghai Company formulated the work Plan of flood Control in 2022 and organized emergency drills to simulate extreme scenarios such as single power supply failure and double power supply failure outside the management office of the flood gate of the Single-current river Reduction. In the emergency drill site, all departments cooperated efficiently, responded quickly and in an orderly manner. Emergency treatment was carried out strictly in accordance with the emergency repair operation specifications. Backup generator power supply was enabled, and gate lifting and signal receiving were in normal operation. Through the drill, Jinghai Company effectively combined the emergency plan with the actual drill, deeply integrated the internal and external coordination and linkage mechanism, improved the flood control response capacity and speed, and provided a strong power guarantee for safe flood control.
“In order to ensure that the flood situation after the rapid response, disposal in place, we will be in advance of the purchase and storage of flood control materials, once the flood situation needs, can be immediately put into use.” “Said Zhang Yu, director of jinghai’s comprehensive service center.
State Grid Tianjin Electric Power Will continue to actively deploy the flood control work, scientifically organize emergency hedging and disaster repair, and further do a good job in the flood control of power stations, DAMS and other important places.
Innovation and upgrading, science and technology to ensure power grid security
Security is the “lifeline” of the power grid, and young people are the new force to ensure the safety of the power grid. State Grid Tianjin Electric Power Co., Ltd. continues to play the role of youth innovation and efficiency, fulfill safety responsibilities, and do a good job of “Green security post” for a smooth summer.
Not long ago, in order to prepare for the summer power supply, under the iron tower of a 1000 kV line, the uHV transmission UAV inspection class of State Grid Tianjin High Voltage Company conducted a special test. The all-weather UAV independently developed by the youth team with an average age of only 30 years old has successfully passed the online acceptance of experts. This equipment upgrade is an important achievement of their striving for the national youth safety production demonstration post, and also adds a new means of scientific and technological guarantee for power supply.
“Hello, teacher expert, what I’m showing you now is the application of using all-weather UAV to conduct local discharge detection. The normal and abnormal discharge parts of insulators are detected respectively, and the difference of waveforms can be found by comparison. “The all-weather uAVs are up to 28 percent more efficient than conventional handheld UV detection devices.” Team members Si Haoyu and Huo Qingyue explain the functional advantages of all-weather drones to experts in front of the camera.
Compared with the conventional uav, all-weather unmanned aerial vehicle (uav) improve the functional and adaptability, matching the visible light, infrared and LLL night vision, a variety of mount, such as partial discharge detection during the summer to “multi-use”, strain clamp overheating and insulator in abnormal discharge, on a rainy day, windy day, special climate conditions, such as fog and sustainable operation, Can effectively support emergency repair, special inspection and other work.
“All-weather uAVs could also be used in a wider range of applications,” he said. “They could be more useful if factors such as lower voltage levels in the distribution network and the surrounding electromagnetic fields have less impact on uAVs than on main network lines.” Nan Jieyin, monitor of uav inspection class, said, “We will also do a good job of verification through practice, so that this achievement can guarantee more equipment, serve more customers, and boost the transformation and upgrading of Tianjin power grid with scientific and technological innovation.”
Next, its Chinese tianjin power will continue to deepen all-weather uavs innovative applications, often do important equipment precision tour, key indicators, at the same time in the power generation side, grid side and load side, fully excavate potential, strengthen the power grid operation state monitoring, intensify security patrol and regulation, improve the flood control and emergency plan, smooth lift the grid of the summer.
