Research On Supply Network Analyzer

Supply Network Analyzer is an electrical measurement instrument which is used to measure, calculate and display power network parameters, such as three-phase voltage, current, frequency, active power, reactive power, power factor etc. With the rapid development of the automation in electric power system, precise measurement and unified management of electrical parameters are essential to guarantee supply network working economically without accident. Since more and more nonlinear equipments have been used in the power supply network, the generated high harmonics current leads to waveform distortion of voltage and current in the supply network. At the same time, power supply network frequency is varying around 50Hz, making traditional direct current (DC) sampling algorithm far from satisfaction. At present, the AC sampling algorithm can't get precious sampling when the sign's cycle is dynamited. A new sampling algorithm to get accurate period by cutting region of sampling sequence has been used in this power Supply Network Analyzer.This paper presents a research on the Supply Network Analyzer design Supply Network Analyzer. Adapt algorithm and embed system's design were analyzed. A compensate algorithm, region cut sampling is proposed to improve the precision in measurement. This algorithm is implemented...
