Cong Hong-shou · Journal of Anhui University of Technology · 2013
Real-time and on-line monitoring is very important for improving power quality.A remote monitoring system of power quality based on ARM9 is designed,which consists of power quality monitoring terminal,GPRS network and computer of power center.The dual CPU construction utilizes DSP to calculate the power quality parameter,ARM9 to actualize the management and storage,and GPRS to monitor the data transmission between monitoring terminal and supervising computer.The design scheme of hardware and software is introduced.Testing results indicate that this system can satisfy the need of power quality remote monitoring,and may produce the important data references for the safety management of power grid.
