Design Of The Partial Discharge On-line Monitoring System Base On FPGA And DSP

In the paper,we propose a system of partical discharge on-line monitering based on FPGA+DSP.In the system,we make use of ADC to aquire the informations which is anologe and make use of FPGA to store them. And then the information can be transfored by TCP/IP to personal computer. So,the remote transmission of information is implemented.The background research of the subject is described in detail in the paper.And at home and abroad are introduced the research situation of partial discharge. And then put forward based on FPGA+DSP partial discharge remote testing system of the overall design scheme. The FPGA technology and the software about FPGA in the design both are described. Each module about the hardware design of the detailed instructions are given.The modules include data acquisition module,A/D acquisition module,data storage module and so oaDetail circuit design principle diagram about every module is given.And,the DSP technology are introduced in briefly. TCP/IP protocol embedded design is implemented through the device of DSP. So the information acquired can be transfored to personal computer by TCP/IP.Then,personal computer to design is illstrated. This software system is compatible with C/S and B/S structure.And the large-scale database management technology is used. Partial discharge signals of the collection, processing, storage, display can be done real-timely. The softwear includes bureau put data acquisition parts, data processing analysis section, graphics, form shows partial, database management.Finally, the operation of the field test system is given. From the system operation condition, we can draw that the system can detect partial discharge of time and place, to meet the requirements of the basic expected. Finally we areas in need of improvement of the system is analyzed using the system needs to improve the idea.
