Partial discharge on-line monitoring system based on FPGA

According to the demand of partial discharge on-line monitoring system, this paper puts forward a new scheme employing field programmable gate array (FPGA) instead of the general-purpose high-speed date acquisition (DAQ). Then, the reconfigurable hardware platform is designed and partial discharge algorithms based on IEC270 are provided. The form of reconfigurable structure and method for realizing the remote reconfiguration of the programmable FPGA are investigated. Using the dataflash chip, DSP can manage and store data up to 512Mbits by serial peripheral interface (SPI) bus. At the same time, this paper discusses the results of software simulation, including data acquisition, data storage, partial dischage algorithm, and communication with DSP. At last, this paper analyzes the possibilities of applying the reconfigurable platform, FPGA-DSP, to the study of new methods for partial discharge on-line monitoring system.
