【摘要】 介绍了一种电力暂态小波分析仪,基于高速的DSP处理芯片TMS320F2812设计了系统硬件结构,并给出了前置机的程序流程图和后台机的软件构成框图。阐述了该仪器基于小波分析及其后处理理论对电力系统暂态信号所作的处理,它可应用于电力系统领域的故障选线、故障测距以及电能质量分析等方面。更多还原

【Abstract】 An electrical transient signal wavelet instrument is introduced in this paper, in which systematic hardware structure is designed based on high speed DSP TMS320F2812, and procedure flow chart of the preposition machine and software block diagram of the background computer are provided. The instrument can deal with transient signal correspondingly based on wavelet analysis and its post processing theory in power system. It can be used effectively in fault location, fault line selection, power quality analysis and others in power system.更多还原
