Study on All-parameter Measurement of Alternating Current Circuit with Digital Signal Process Technology

研制了采用TMS320C32浮点32位数字信号处理器(DSP)芯片为核心的测控装置,实现了快速、准确、全面的测量。

The calculation methods are discuss ed in order to get all -parameter of alternation current circuit,such as t he voltage and current virtual value,active power,inactive power,power facttor,harmonic di stortion,harmonic power,sequence value of three phase circuit,un-balanced degree.This paper propose s a method with low calculation and hi gh accuracy.A new measurement and co ntrol equipment is developed.The 32bit floating point Digital Signal Processor TMS320C32is used as the Central Process Unit,t his equipment can fulfill real time measurement and detection for the analysis of alternating current circuit in power system.
