摘要
为了提高重要负荷的用电连续性、可靠性和稳定性,提出了一种以TMS320F2812作为核心、以断路器为控制对象的智能开关的硬件和软件设计方案.该系统充分利用DSP丰富的硬件资源和强大的数据处理能力,实现了电源电压、电流监测,断路器监控,键盘和显示,RS485通讯等功能.针对风力发电系统出现的电压跌落现象,分析了利用基于有效值和小波变换相结合的方法检测电压跌落的幅值和定位跌落的时刻点,实验结果表明了该系统具有稳定性好,精度高,响应快和抗干扰能力强等特点.
In order to improve the continuity,reliability and stability of the major load,a new hardware and software design of Intelligent Switch Device is proposed.In this method,the TMS320F2812 is used as a control core and the Circuit Breaker is used as a control object.This system not only takes full advantage of rich hardware resources and powerful data processing capabilities of the DSP,but also realizes the power supply voltage,current monitoring,circuit breaker control,keyboard and display,RS485communication and other functions.For the phenomenon of voltage sags in the wind power generation system,a method based on RMS and wavelet transform to detect voltage sag amplitude and locate the fall time point is analyzed.The experimental results show that the system has performances of good stability,high accuracy,quick response and anti-jamming capability.
