Wuxi Power achieve information collection transmission carrier
July 5, Wuxi Power Supply Company in lake 10 kV line "Nishiyama change", "change the village" two stage area, the successful completion of information collection system pilot carrier transmission installation and commissioning time through the signal transmission. So far, the company in Jiangsu province first to complete the smart meter information collection system pilot carrier transmission installation, marking has added a new information collection mode, enter the information collection is really "wireless era."
By the end of June, Wuxi city to complete the installation of the smart meter users totaled 770,000, putting information collection operation has 500,191. One of the information collection system construction as an important smart grid construction projects, Jiangsu Provincial Power Company will be established in early carrier of electricity information collection formula installation program. The program applies to the case of low-voltage distribution transformer station in the user area live scattered, making it impossible to connect the communication line between the distribution transformer collector and smart meters, such as private houses agglomeration areas, construction sites and other temporary. Carrier transmission mainly a distribution transformer station area as a unit, the smart meter, collector, concentrator composed of the carrier, and before the "little radio" transmission system compared with the low cost, the technology is mature, less affected by the geographical environment and easy interference is eavesdropping and other advantages. Wuxi Power Supply Company as the project pilot units, and determine requirements for a pilot installation in this mode, the first time to coordinate, organize the relevant units Scene Investigation user, station area, determine the pilot area and the construction of a pilot program. The electricity company acquisition engineering group on July 2 entering the construction. After three days of intense construction, two stage area, 155 All User installation is completed, the successful completion of the provincial pilot carrier collection. The pilot installation will succeed better user load, power, voltage, and other important information in real-time online monitoring and collection services for the provincial company "SG186" system, provide a technical basis for the realization of a comprehensive pre-control tariff collection, and smart electricity settlement .
