Shanghai: Power Fiber to the Home to Promote Smart Grid Applications

As one of the pilot cities for the commercialization of electric fiber to the home, Shanghai has realized the commercialization of smart TVs. The reporter walked into the 1355th Lane of Yingchun Road, which is located in the ninth urban district of Shanghai's Lianyang area. In 2011, the district was selected as the smart residential demonstration area for residents of the power grid to build an open public information platform.

The ninth city is a high-rise residential community. The community covers 21 buildings, 1054 residents, and a total construction area of ​​196,000 square meters. The demonstration project involves smart meter reading services and external network services (ie, Internet access, IPTV, voice services), deploys Ethernet passive optical networks, and utilizes a synchronous digital system transmission network in Pudong to deliver the distribution network carried by Ethernet passive optical network equipment. The automation, load measurement, and metering services are transmitted to the base server to realize the processing and distribution of power consumption services.

Fiber-to-the-home smart grid application The reporter saw that after the implementation of the power fiber to the home, the ninth urban community realized smart grid functions such as power consumption information collection, distribution network automation, and medium-to-low voltage line loss ratio. According to the ninth urban property management personnel, after using the power optical fiber, the resident's electricity consumption information collection method uses the smart meter to upload data to the concentrator through the two-core twisted pair first, and then directly transmits the data to the power company through the power optical fiber. In practical applications, the collection success rate and accuracy rate basically reach 100%, and the acquisition frequency can be achieved in real time.

The original distribution automation communication method mainly depends on the power line carrier method. However, in practical applications, the carrier communication mode has the problems of unstable communication, narrow bandwidth, and large environmental impact. The optical fiber communication has the advantages of stable communication, large capacity, and high speed. It fully meets the communication requirements of telemetering, remote signaling, and remote control “three remotes” for distribution automation, and fully satisfies the requirements for self-healing of distributed feeders on the stability of communications. The advantages are very high. Significant.

The staff of Shanghai Electric Power Company stated that the low-voltage line loss ratio is a method of conducting line loss lean management by comparing customer power consumption information data with low-voltage transformer power supply data for customers. The data of the low-voltage line loss ratio is collected on the one hand from the power consumption information, and on the other hand from the load side recorder on the grid side. The load recorder is mainly installed in the rod change and box change. Due to the constraints of communication conditions, poles can only adopt wireless public network communication methods. There is also the problem that the signal is easily shielded by using the wireless public network in the box change. Using optical fiber can effectively improve the success rate of data acquisition and transmission. The power optical fiber provides reliable and accurate data on both sides of the power supply for the low-voltage line loss ratio, and realizes an accurate real-time comparison of the line loss in the Taiwan area, which has a huge advantage in the management of the line loss in the low-voltage area.

Achieving smart power consumption and saving electricity Power FTTH provides more reliable, higher-speed, and more convenient broadband Internet access services for residents in the community. At the same time, it not only enables residential residents to enjoy high-definition TV programs with rich content, but also provides various interactive media services for customers, including smart power, live video, high-definition on-demand, news and information, stock securities, and somatosensory games, as well as smart applications. Electrical information.

Customers can leave their homes, collect and analyze electricity data, formulate reasonable plans for household electricity consumption, promote energy conservation and emission reductions, and realize energy conservation and scientific electricity use. Related data also provide reasonable electricity consumption for residents after implementing ladder prices. Also has a positive reference value.

As of the beginning of August, 2012, the implementation of the Philippine fiber-to-the-home project for the implementation of the State Grid Information and Communications Co., Ltd. has completed construction of 200,000 mature residential areas in Shanghai, and all of them have commercialization and promotion operating conditions. The number of smart TV users has exceeded 10,000 households. This marks an important step in Shanghai Power's fiber-to-the-home project from construction to commercialization and promotion, and has laid a solid foundation for the construction of "Smart City" in Shanghai.
