Design of Electrical Parameters Measuring System of Gas Power Station of Coal Mine

摘要: 针对现有煤矿瓦斯发电站电参数测量系统存在功能单一、可靠性差的问题, 提出了一种基于DSP的电参数测量系统的设计方案。该系统以DSP TMS320LF2407A为控制核心，可同时测量任意三相交流电的电压、电流、有功功率、无功功率、功率因数等参数。测试及实际应用结果表明,该系统测量误差小于0.5%，具有较高的稳定性和较好的抗干扰能力。

Abstract: In view of problems of single function and bad reliability of existing electrical parameters measuring system of gas power station of coal mine, the paper proposed a design scheme of electrical parameters measuring system based on DSP. The system takes DSP TMS320LF2407A as control core and can measure parameters of voltage, current, active power, reactive power and power factor of three-phase AC. The results of test and actual application showed that measuring error of the system is less than 0.5% and the system has higher reliability and better anti-interference ability.
