Study on ARM-Based Power Quality Monitoring and Control Instrument
Weilin Wu · 2006
The paper describes the research of ARM based electrical power quality monitoring and control instrument including of software and hardware.The hardware consists of voltage and circuit module,LCD module Ethernet module and USB module,which are introduced in detail.Electrical parameters algorithm is deduced and optimized in software module.Task is dispatched by μC/OS-II Real time operating system which is portable,scalable and preemptive.It can manage multitask and strengthen the system's reliability.The simulation experiment is done for measuring the parameters and the data is also analyzed.The result of test indicates this design can accord with the requirement in power quality monitoring.Comparing with other designs,it has advantages in performance and price.Smaller computation volume make it suitable to be installed in large quality.Application of USB makes large data saved at any moment and the work status of electrical network monitored expediently.
