System for controlling operation parameters of wind power current transformer based on DSP and ARM

Abstract

The invention relates to a system for collecting and displaying operation parameters of a wind power current transformer based on a DSP and an ARM. The system comprises a data collection unit, a data interaction unit, an Ethernet interface unit, a virtual oscilloscope unit and a power supply unit. The data collection unit is used for collecting a network voltage signal, a grid-side current signal, a machine-side current signal and a stator voltage signal on spot, wherein all the signals reflect the operation parameters of the power current transformer; the collected signals are input to a secondary primary conditioning circuit; the primary conditioning circuit receives, filters and amplifies the input signals, and then sends the input signals to the data interaction unit. The Ethernet communication technology is applied to the system for monitoring and controlling the parameters of the wind power current transformer, data of the on-spot parameters of the wind power current transformer are collected and processed through a dual-core processor, the collected data are interacted through an auxiliary control ARM unit and the virtual oscilloscope unit of an upper computer, and the shortcoming of the poor human-computer interaction ability of the DSP is overcome.
