摘要
介绍了波形畸变系统电平衡参数的理论计算方法和同步采样测量方法，并对这些方法进行了深入的分析和研究。导出了非同步采样和有周期误差时电平衡参数测量误差的数学模型，提出采用同步锁相采样控制技术来减少或消除测量误差的方法，给出了测量装置的硬件结构方块图。
Present theoretical computing method and synohronous sampling computing method of electric equilibrium parameters for waveform distortion system. These methods are analysed and studied in depth. The mathematical model of electric equilibrium parameters measurement error is derived while nonsynchronous sampling and period error existed. To reduce and remove measurement error, presents and effective measure which uses synchronous phase-lock sampling control technique. The measurement instrument hardware structure block diagrams arealso given.
