Simulation and Application of PLD in Electric Power System Circuit

Abstract:

Programmable Logic Device(PLD) has been widely used in hardware circuit, and it has evolved into two types: Complex Programmable Logic Device(CPLD) and Field Programmable Gate Array(FPGA). This paper takes small current grounding in electric power system as background, uses xc95144, a representative CPLD of Xilinx Company in the signal collecting circuit to collect voltage and current signals, and do some other operations to spare circuit board area. This paper also tries to translate the schematic into VHDL-described text and do simulation to the text.
