Smart community is still in its infancy but has unlimited prospects

The Smart Electricity Residential Community realizes the power-fiber optical access to homes, and has the conditions for “triple play”. Wang Kairui is a resident of the Mingzhuyuan Community on the lakeside. “Through this screen, you can remotely control all your home appliances and adjust the temperature of your air conditioners and water heaters. You can also use 3G mobile phones or network control appliances while you are away from home.” She pointed to the smart interactive terminal on the wall and said that by tapping the screen, the electricity fee can be turned on. Query, power curve, energy consumption analysis, charge status and other options.

"The district has replaced the smart energy meter and intelligent terminal equipment, and realized the automatic collection of electricity information." The staff of Lake Pearl Pearl Community District introduced that the smart meter has the functions of two-way metering, automatic control, and automatic collection. It is planned for the community in the future. The rooftop solar distributed energy access provides an important guarantee. “Afterwards, households are no longer simply a party to electricity consumption. They can also sell electricity to the power supply sector, which can be used for photovoltaic power generation on rooftops.”

In addition, the power department staff said that smart home can allow residents to choose a series of value-added services such as “smart security”. If there is a gas leak or other unexpected situation at home, the system will automatically send an alarm to the property management center and send the alarm information. To households' mobile phones; to guide people to use electricity resources more scientifically and reasonably, and to promote the development of low-carbon economy. For example, in the peak period of electricity consumption, tenants can choose to turn off some home appliances according to the preset electricity consumption strategy, and wait until the low period. Automatically enabled.

Tan Yongxiang, deputy general manager of Jiangxi Provincial Electric Power Company, told reporters that compared with the ordinary community, the smart electricity community has realized the power of optical fiber to enter the home, with the "triple play" condition, that is, while providing electricity, it can realize the telecommunication network. , radio and television networks, Internet transmissions on the same network, to avoid the repeated construction of residential communications networks.

"The convergence of telecommunications networks, radio and television networks and the Internet has become a major trend in the future of urban information services. Through the construction of smart communities, we have strived to achieve 'four network convergence', which not only reduces the overall cost, but also facilitates the later period. The operation and maintenance.” Zhao Zihui, Deputy Director of Marketing Department of Heilongjiang Harbin Electric Power Bureau, said, “At the same time, when laying cables, a layer of optical fiber lines is wrapped around the wires. Signals from telecommunications networks, radio and television networks, and the Internet are transmitted at the same time. After testing, they can reach 100M. The transfer rate of home users is only 2 minutes for users to download a high-definition movie, which is 50 times faster than traditional ADSL access to the Internet.

The smart community is still in the “conceptualized” experimental stage, but its future development prospects are broad. The Jiangxi Provincial Electric Power Company has carried out the construction of an intelligent community for the Pearl Court in Nanchang Lake, which is expected to be transformed into the nation’s first ever-built residential practical smart community. “Compared with current smart residential communities built in places like Beijing and Shanghai, the biggest feature is not only the functional display, but its practicality.” The staff said that in addition to the exhibition room, there are more than 500 households in Mingzhuyuan Community. Among the households, 210 households were included in the first batch of implementation of the smart electricity transformation plan. At present, the installation and commissioning of smart devices related to more than 160 households in the community have been completed, enabling the electricity consumption of these ordinary households to realize smart electricity use.

In the construction of intelligent communities, part of its power intelligence is directly invested by power grid companies, and households are responsible for installing the necessary supporting intelligent terminal equipment in the home without replacing the existing home appliances. "As long as the purchase of smart sockets, it can meet the needs of the 'intelligent' conversion of ordinary household appliances. Therefore, from the perspective of users, smart power consumption will not increase the cost of use," said the person in charge of the marketing department of Jiangxi Electric Power Company. As the smart power transformation is a systematic project, considering the cost input and scale efficiency, it will not accept the ordinary residents' applications for transformation. At present, the government and related departments have not yet issued relevant policies for the smart electricity construction of new buildings or communities. Therefore, there is still a process for smart electricity construction and its promotion and application.

“Although the smart community is still in the 'conceptualized' experimental stage, its future development prospects are broad, and it has a demonstration effect on future power grid upgrades and residents' information life,” said Wang Zhibin, deputy director of Harbin Electric Power Bureau.

The traditional power grid is expected to leapfrog the modern smart grid. “Smart grids are strong, self-healing, compatible, economical, integrated, and optimized. This is not simply an improvement in several technical parameters. It is a leap from the traditional grid to the modern grid. It is the grid. Upgrade from 1.0 to 2.0, said Huang Wu, a special engineer in the marketing department of Harbin Power Bureau.

In 2009, the concept of “Strong Smart Grid” was first proposed by the State Grid Corporation of China. It has the characteristics of informatization, automation, and interaction. It includes all aspects of the power system and realizes a highly integrated integration of “power flow, information flow, and business flow”. .

“The smart grid is an integrated system that includes many links such as power generation, distribution, and user terminals, some of which are visible to the user and some are invisible. Invisible power distribution automation is the key to ensuring the safety and reliability of power supply. , is a highlight of the smart grid.” Huang Wu said, “'smart' performance in the automatic selection and removal of fault lines and other functions, can effectively reduce the power outage range, shorten the power outage time and deal with failure time, but also in the global scope The use of 'unattended' to replace the current manual records, judgments and follow-up operations fundamentally guarantees the stability and reliability of the city's power supply." By the end of the "Twelfth Five-Year Plan," the power supply reliability in the Harbin power supply area will have reached 99.99%, comprehensive voltage pass rate of 99.8%.

According to the development plan of the smart grid announced by the State Grid Corporation of China, from 2011 to 2015, it is a comprehensive construction phase, a strong smart grid construction standard has been formed, rolling revision of development plans, and the construction of a strong smart grid has been fully rolled out.
