With the development of Internet technology, people's lives are gradually showing the characteristics of wisdom. Electricity, which is very important for people's lives, is also facing the wisdom reform. Let's see what efforts Tianjin has made to this end.

Wisdom Grid Creates "Wisdom" Tianjin Makes Our Life Wisdom

"In order to improve the efficiency of emergency repair, during summer, we arranged 102 fixed distribution emergency repair stations, 1119 personnel, 315 vehicles, ready for emergency repair at any time." Li Congli, deputy director of equipment department of State Grid Tianjin Electric Power Company (hereinafter referred to as "State Grid Tianjin Electric Power"), said. Summer is the peak period of urban electricity consumption, power supply security is directly related to all aspects of public life. Ensuring the safety of power supply has become an important issue for power companies to meet the peak of summer. Recently, the reporter learned from the press conference of Tianjin Electric Power, which was held by Tianjin National Grid, that in order to maintain the stable operation of the power grid during the summer, Tianjin Electric Power adopted many measures, such as equipment management, hidden danger investigation, power grid transformation, and applied the universal protection of the power Internet of things. Safety of summer power grid during peak hours. At the same time, the wide application of the Wisdom Grid in the Internet of Things has also made the Wisdom Grid come into people's lives and become a smart city.

Ubiquitous Power Internet of Things into a Summer Bright Spot

Reporters learned from the press conference that this summer, the peak load of Beijing-Tianjin-Tangshan power grid in Tianjin power grid is expected to reach 69 million kilowatts, an increase of 6.4% over the same period last year. Among them, Tianjin is expected to have a maximum load of 16.5 million kW during peak summer, an increase of 7.77% over the same period last year. The operation of the power grid is faced with obvious load growth, shortage of power supply and demand in some periods, and heavy equipment load in some areas. "In order to ensure the safety of power supply during heavy load period, we have constructed a 500-kilovolt double-circuit line project from Beijing Xinhangcheng to Tianjin Nancai, perfected the structure of Tianjin power grid and enhanced the external electric power capacity; constructed a 220-kilovolt high-tech zone transmission and transformation project, Yuyang Station capacity expansion project, Chunhua Road and environmental protection park expansion project, and upgraded the power grid. Power supply capacity. We completed 240 scheduled overhauls of main network equipment and 14 unit overhauls ahead of schedule to ensure the safety of transportation equipment in summer, strengthened emergency duty and response to emergency disposal, established and improved emergency duty system, and established emergency mechanism such as bad weather and flood alarm. Wang Gang, director of Tianjin Electric Power Regulation and Control Center of State Grid, said.

In addition, the establishment of ubiquitous power Internet of Things is also a new highlight of this year's peak summer. Through the application of modern information technology and advanced communication technology such as mobile interconnection and artificial intelligence, the ubiquitous Internet of Things (IOT) of power system realizes the interconnection of everything in power system and human-computer interaction. "Among them, the comprehensive development and utilization of clean energy, load demand response based on virtual power plants, active distribution network, etc. will respond more quickly in many aspects, such as power balance, equipment operation and maintenance, potential hazards investigation, situation awareness, etc., during the summer peak load period, which can effectively alleviate the pressure of power grid operation. Energy big data center will also provide guidance and services for customers to use energy reasonably and economically. Wang Gang said.

Intelligent Meter Helps Users Understand Sub-item Electricity Use
Based on the ubiquitous power Internet of things, Tianjin Electric Power uses smart energy to support the construction of smart cities.
In the smart energy Town Exhibition Center on the second floor of the integrated energy service center, a smart measurement system display screen shows the monitoring screen of 5 buildings, 2 units and 701 rooms in the talent apartment on the right side, and the energy efficiency analysis map of residential users on the left side, which clearly indicates that the air-conditioning power consumption of this user accounted for 18.5% of the daily electricity consumption on that day, corresponding to the electricity expenditure. Output is 0.6 yuan, the daily power consumption of electric water heater accounts for 44.68%, and the corresponding electricity expenditure is 1.623 yuan. Through intelligent measurement system, users can see the daily power consumption, weekly power consumption, monthly power consumption and corresponding electricity bills of different appliances at a glance. What kind of "black technology" is used in this system?

"In the smart energy town, we deployed a new type of smart meter, which can obtain real-time power and operation curves of different devices for each user." Yu Jiancheng, deputy director of Tianjin Electric Power Internet Department of State Grid, said. Installation of smart meters can help users understand the situation of sub-item electricity consumption, thereby reducing household electricity expenditure.

In addition to providing intelligent services such as intelligent measurement system, people's clean and green electricity, low cost, high quality and convenient and flexible energy services will be connected with smart grid. "In the aspect of clean and green electricity, new green energy sources such as photovoltaic, wind power, ground source heat pump and so on are connected to the power grid through smart grid to realize energy-saving absorption and provide green and clean energy for the common people; in the aspect of low cost and high quality, new energy-saving equipment such as regenerative electric heating is used to help urban and rural residents and schools. Build a coal-free living environment, and apply the integrated energy technology of smart grid to achieve energy saving and consumption reduction in planning, operation, maintenance, trading and other aspects, and improve energy utilization. Taking the photovoltaic ground source heat pump developed by the Beichen Development Zone Management Committee in 2017 as an example, it saves 2.2 million electricity during two years of operation and saves energy consumption. 1 million 500 thousand yuan, improve energy efficiency 19%; convenient and flexible, through the "Internet +" smart service, users will realize real-time query of water and gas thermoelectric data in the home, the mobile phone can pay various energy bills. Yu Jiancheng said.

Effective integration of smart grid and smart city

It is understood that in 2018, Tianjin Electric Power Company of the State Grid
