【摘要】：箱式变电站是现代电网中一种重要的变配电设备,随着经济的发展,人们对电网的智能化要求越来越高,为了实现供电质量的可靠性和稳定性,同时减少电力工作者的工作量,在箱式变电站的基础上设计了一种基于GPRS通信的智能箱式变电站监测方案,它集变电站的数据采集、传输和显示于一体,提高了箱式变电站的自动化运行水平,实现了箱变参数的无线实时监测功能。主要采用模块化的设计思想,通过对数据采集模块、DSP数据处理模块、GPRS无线传输模块和上位机软件运行模块的设计,达到监测系统的总体要求。该系统以DSP2407微处理器为核心器件,通过设计硬件采样电路实现箱式变电站三相电压、电流、箱体内温度和开关量的采集,并对采集到的数据进行处理,计算出变电站的电压、电流有效值、功率、功率因数等量;GPRS模块主要采用GTM-900C开发板实现数据采集端和上位机的通信功能,将处理后的数据实时传输到使用Lab VIEW编写的上位机显示界面上,上位机主要是显示数据,同时还能够判断断路器等开关量的开断状态和故障情况,并通过相应指示灯提示。最后对系统进行了整体的调试和分析,达到了预期设计目标。
[Abstract]:Box-type substation is an important transformer and distribution equipment in modern power network. With the development of economy, people demand more and more intelligent power grid. In order to realize the reliability and stability of power supply quality and reduce the workload of power workers, Based on the box substation, a kind of intelligent box substation monitoring scheme based on GPRS communication is designed. It integrates the data collection, transmission and display of the substation, and improves the automatic operation level of the box substation. The wireless real-time monitoring function of box variable parameters is realized. Through the design of GPRS wireless transmission module of DSP data processing module and the upper computer software running module, the general requirements of the monitoring system are achieved. This system takes DSP2407 microprocessor as the core device, realizes the collection of three phase voltage, current, temperature and switch quantity in box substation by designing hardware sampling circuit, and processes the collected data to calculate the voltage of substation. The GPRS module uses GTM-900C development board to realize the communication function between the data acquisition end and the host computer, and transmits the processed data in real time to the display interface of the host computer written by Lab view. The upper computer mainly displays the data, and can also judge the switching state and fault situation of the circuit breaker and so on, and indicate by the corresponding indicator lamp. Finally, the system is debugged and analyzed, and the expected design goal is achieved.
