用电设备阻抗性质识别及其电参量测量与测试

Impedance Properties Distinguishing of Electric Equipment and Its Electric Parameter Measurement and Test

在传统的电能测量系统中,一般采取8051、80C196等普通单片机作为核心部件,无法进行实时高速采样和实时处理。为了满足现代电力系统的新要求,本装置研制使用TI公司的TMS320C5402DSP芯片作MPU,AT89C52作MCU,CPLD——EPM7192E完成所有时序的产生及逻辑的控制,并采用一种新的相角测量方法,从而能实时提供电压、电流、有功功率、无功功率、频率等电能计量的基本参数,并能实时进行谐波分析,完成负载的性质识别。

In the traditional electric energy measurement system, ordinary microcontrollers, such as 8051and 80C196, are used as the key parts. High acquisition speed and real-time signal can not be reached. To meet the new requirements of modern power system, this device uses V5402 as MPU, AT89C52 as MCU, CPLD-EPM7192E as timing and logical control unit, adopting a new way of angle measurement to complete electric parameter measurement such as voltage,current,function power,non-function power,frequency and so on. The harmonic analysis and the load properties distinguishing are finished and carriedout respectively.
