Abstract

A data acquisition system for overvoltage in power system based on ARM and CPLD is discussed.The system includes a data acquisition module and a monitoring module.The data acquisition module with pre-trigger acquisition and variable sampling speed technique employs a CPLD as its main control chip.An ARM chip is adopted as the CPU in monitoring unit

which stores the over-voltage data in CF card and transmits them to the PC work station through Ethernet.The system has many advantages such as small dimension

convenient networking and high performance to price ratio.The test results indicate that the acquisition system has high accuracy and stability to satisfy the requirements of overvoltage monitoring for power system.
