摘要
针对以 16位微处理器为核心的电力智能化监控系统 ,提出了一种采用总线结构的模块化硬件平台设计方法 ,分析了系统的组成原理以及各参数变量的采集与处理 ,其中包括电压和电流的有效值、有功功率、无功功率的计算。着重讨论了电压 U的傅氏滤波算法。合理使用这种算法 ,大大提高了系统的运算速度和精度 ,达到了快速、精确的目的 ,从而使电力系统更加安全。
For the intellectualized electric power monitor system based on 16-bit micropro cessor.A design method,which used bus structure and moduled hardware platform,is implemented.then the constitute principle of system and the collection and trea tment of several parameter variables are analysed.It includes the calculation of the valid value of voltage and current, active and non-active power.The Fourie r filter algorithm of AC voltage U is introduced emphatically.By using this algo rithm reasonably.The calculate speed and accuracy of the system are enhanced and the electric power system runs safely and stably.
