【摘要】：General Packet Radio System简称GPRS。在我国,GPRS是非常成熟的网络技术。无论是其硬件设备设施的价格还是网络商收取的服务费都非常经济。随着农村村民生活质量和生产水平的提高,农村用户对生活和生产用电质量及可靠性的要求也越来越苛刻。为了减少停电持续时间及停电范围,对农村10kV电网的断路器进行三遥控制已经迫在眉睫。但是,长期以来断路器控制器通信高昂费用问题成为了农村电网发展的瓶颈。随着移动无线网络的快速发展,GPRS网络越来越具备经济性,借助GPRS公用网对农网分界断路器进行控制,可以降低电网运营成本,实现资产快速回报。本课题针对农村电网的实际情况及需求,设计了一款基于GPRS通信方式的断路器控制器。该控制器硬件主要由MAX232串口模块两块,SIM300通讯模块一块,STC单片机一块以及其他附件组成。针对于农村电网中断路器的功能要求,设计好控制器的主程序。主程序首先采用C语言开发工具Keil c51 uVision2进行编写。通过编译完成后,再使用STC-ISP工具将程序写入单片机中。其中,SIM300的通信控制通过对其发出AT指令来完成。在将控制器制作完成后,进行了简单测试,并提出了控制器在实际应用中需要完善的抗干扰措施。本论文讨论的设计及实施步骤,对百色农村电网的断路器控制器制造和投入运行具有一定的参考价值。
[Abstract]:General Packet Radio System. GPRS is a very mature network technology in China. Both the price of its hardware and facilities or the service charge charged by the internet vendor are very economical. With the improvement of the quality of life and the level of production of rural villagers, the demands of rural users on the quality and reliability of power consumption in life and production are becoming more and more stringent. In order to reduce the duration and range of power outages, it is urgent to carry out three remote control of circuit breakers in rural 10kV power network. However, for a long time, the problem of high communication cost of circuit breaker controller has become the bottleneck of rural power grid development. With the rapid development of mobile wireless network, GPRS network is becoming more and more economical. Using GPRS public network to control the circuit breaker can reduce the operation cost of power network and realize the quick return of assets. A circuit breaker controller based on GPRS communication mode is designed according to the actual situation and demand of rural power grid. The hardware of the controller is mainly composed of two modules of MAX232 serial port module and two communication modules of SIM300, a single chip microcomputer and other accessories. According to the function requirement of circuit breaker in rural power network, the main program of controller is designed. The main program is written with C language development tool Keil C 51 uVision2. After compiling, then use the STC-ISP tool to write the program into the single-chip microcomputer. The communication control of the SIM300 is accomplished by issuing AT instructions to the SIM300. After the controller is finished, a simple test is carried out, and the anti-interference measures for the controller in practical application are put forward. The design and implementation steps discussed in this paper have certain reference value for the manufacture and operation of circuit breaker controller in Baise rural power network.
