【摘要】：目前,我国电能信息的智能采集已经达到了一个新个高度,各省对于用户用电信息的智能采集都在百分之九十七以上,只有相当少部分的地下室、偏远山区以及矿井等特别环境的用户难以采集。为实现电能信息采集的全覆盖、全采集,根据智能电网的要求,本方案中研究了一种基于中压电力线通信的采集方法。电能信息采控系统主要包括了对用户用电信息的采集以及控制,主要包括的单元有智能用户表、低压采集通信模块、数据采集器、上行通信模块以及后台采集主站,其中,低压采集通信方式主要包括低压载波、短距离无线以及485有线连接三种方式;上行通信方式主要包括无线GPRS网络通信、光纤通信以及有线以太网通信。目前,在我国电力采集系统中使用最多的低压通信方式是低压载波,上行通信方式使用最多的是无线GPRS通信。在中国,中压输电线路的遍布最广、线路结构复杂,中压载波通信技术利用现有的中压输电线路作为传输媒介,不需要额外架设通信通道,安装方便,便于操作,更适用于农村。与无线GPRS公网通信相对,不需要第三方移动公司的支持,无后期运行费用;与光纤通信通信相比,前期的建设费用低廉。对于本论文的研究方案,中压载波通信技术在电能信息采集系统中的应用,阐述了中压载波通信技术如何完成对于山区无公网GPRS信号区域用电用户用电信息的采集。最后,本论文结合电力系统的电能信息采集系统,阐述中压载波通信的几项的关键技术、本论文的研究方案以及具体的实施办法。
[Abstract]:At present, the intelligent collection of electric energy information in China has reached a new height. The intelligent collection of electricity information for users in all provinces is over 97%, with only a relatively small number of basements. Users in remote mountain areas and special environments such as mines are difficult to collect. In order to achieve full coverage and full acquisition of power information, according to the requirements of smart grid, a method of acquisition based on medium voltage power line communication is studied in this scheme. The power information collection and control system mainly includes the collection and control of user power information, including intelligent user table, low voltage acquisition and communication module, data acquisition device, uplink communication module and background acquisition main station, among which, Low-voltage acquisition and communication mainly include low-voltage carrier, short-range wireless and 485 wired connection, and uplink communication mainly includes wireless GPRS network communication, optical fiber communication and wired Ethernet communication. At present, the low-voltage communication mode is the low-voltage carrier, and the uplink communication is the wireless GPRS communication. In China, the medium voltage transmission line is widely spread, and the structure of the transmission line is complex. The medium voltage carrier communication technology uses the existing medium of medium voltage transmission line as the transmission medium. It does not need to set up additional communication channels, and the installation is convenient and easy to operate. More suitable for rural areas. Compared with wireless GPRS public network communication, it does not need the support of the third party mobile company, and has no late operation cost. Compared with optical fiber communication, the construction cost of the early stage is low. For the research scheme of this paper, the application of medium voltage carrier communication technology in the power information acquisition system is discussed. How to complete the acquisition of power information for the area of GPRS signal without public network in mountain area is described. Finally, this paper combines the electric energy information collection system of the power system, expounds several key technologies of the medium voltage carrier communication, the research scheme of this paper and the concrete implementation method.
