In the aspect of smart meter replacement, the power meter as the most end of the power grid is the foundation for realizing the intelligence of the power grid, and is the key link between the user and the power grid. The application of the smart meter will promote the use of the energy use model and the power consumption management model. The change is in full compliance with Zhangjiakou’s goal of transforming clean energy. However, judging from the actual situation, the Zhangjiakou region is a mountainous region, and each region has a large difference, and it has a wide range of points, a large number of power users, and the power consumption is complex. When all types of high and low voltage users choose to install smart meters, they must fully consider the actual conditions in the field, which will hinder the smart meter replacement work.
In order to meet the needs of the society and ensure users safe, rational, and convenient use of electricity, and promote the construction of smart grids, in March 2015, the Zhangjiakou Power Supply Company promoted the use of a long-distance electricity tariff control system in urban areas to enable users to pay electricity charges remotely. It is understood that Cheng Fei-controlled to rely on power supply marketing business applications and electricity information collection system to rely on, can achieve real-time billing, reminder of the customer's early warning, trip power outage, closing and other remote control functions. Thanks to its advantages of convenience and intelligence, 90,000 households have implemented long-distance fee control since the implementation of one year, and have taken further steps toward building a smart city. At present, remote fare control is still in the promotion stage.
In terms of gas meter reconstruction, the use of pipeline liquefied gas in Zhangjiakou City has a long history, dating back to 1996, involving more than 12,800 users. In order to ensure the smoothness of the renovation project, as with smart meter replacement, site surveys are required. Different liquefied gas reform plans are formulated for different geographical locations, gas pipeline locations, and surrounding environments. According to relevant sources, in the renovation process, the gas districts with better gas facilities will be replaced by gas meters and valves; the districts with serious safety hazards such as severe pipeline aging and secondary decompression in the interior will be abandoned. The pipeline is reinstalled and replaced with natural gas when conditions permit.
According to statistics, Zhangjiakou CNPC Jinhong Natural Gas Co., Ltd. is the only gas company with natural gas franchise in Zhangjiakou City. Since the pipeline liquefied gas replacement work began in 2011, it has cumulatively reconstructed more than 11,000 pipeline liquefied gas users.
In terms of water meter reconstruction, Zhangjiakou City has standardized the construction and management of water supply facilities, promoted the “one-on-one†conversion of water, and successively issued a number of “Implementation Opinionsâ€, adopting “first new and old, first built, and later The "easy-to-difficult" approach follows the work steps of "mature batch, transform batch, accept batch, and take over batch" and plans to complete secondary water supply management reform by 2020. The comments clearly stated that the use of advanced water metering equipment and intelligent management methods was encouraged in the transformation of households.
In addition, as early as 2015, Zhangjiakou Water Supply Equipment Company signed a cooperation agreement with Sanchuan Co., Ltd. Sanchuan will provide 100,000 Internet of Things water meters and related services for Zhangjiakou City Water Renovation. This greatly accelerated the pace of building smart cities in Zhangjiakou. With the upgrading of intelligence, the Internet of Things meter application will become more and more extensive, which will help Zhangjiakou to stay ahead of the trend of the times.
Xiao Bian concludes that Zhangjiakou planned 20 million square meters of clean heating area this year and plans to dismantle more than 400 coal-fired boilers in the urban area and its surrounding areas. Now it is looking for relevant experts and enterprises to seek economically viable, locally-acceptable solutions. Xiao Bian wants to say that the market's east wind has already blown up, only to see who can win.
[Chinese Instrument Network Instrumentation Depth] Today, the coordinates of Hangzhou Xiaobian saw a lot of groundwater manhole cover opened on the way to work, along the way there are construction banners that read "Ready for the G20." Looking at the massive construction team Xiao Bian can not help but think about the news just two days ago, "Zhangjiakou water vapor pipeline renovation project," as a national demonstration base for clean energy to lead the Olympic Winter Games in Zhangjiakou has been made in urban transformation Part of the results. At present, 680,000 smart meters in the whole city of Zhangjiakou have been replaced, 12,800 liquefied gas pipelines are being transformed, and the secondary water supply and household surface reconstruction are expected to be completed in 2020.
