摘要
针对变电站数字化改造,设计了一种以三相电压、电流及功率信号为内容的采集与处理系统,采用TMS320F2812为核心处理器,信号采集系统由霍尔电压、电流和功率传感器和A/D芯片组成,数据处理由数字信号处理器和算法负责,得到的数字信号通过以太网传送给调度室,用组态软件实时显示数据并提供报表给相关人员分析以做出决策来维护电网的稳定运行。实验表明:系统精度高、实时性好,具有一定推广价值。
According to digital transformation of a substation,this paper designed an acquisition and processing system which took three-phase voltage,current and power signals as content.The system used TMS320F2812 as the core processor.Data acquisition system consisted of the Hall voltage,current,power sensor and A /D chips.Digital signal processor and algorithm were responsible for data processing.The digital signal which is get from data processing is transmitted via Ethernet to the control room.The configuration software provides digital data for relevant personnel to analysis,then make decisions,which is benefit for maintain the stable operation of the grid.Experiments show that the system has some promotional value and its precision is high.
