基于Labwindows/CVI的同步发电机励磁系统的监测

摘要

As an example of WLZ synchronous generator excitation system, an applications that monitor the state of excitation system,was developed using the virtual instrument software Labwindows/CVI. Completed by the application of WLZ condition monitoring and the program also use a queue data structure in the full utilization of the host computer's buffer to complete the functionality of the system' s fault recorder. At the same time, the program using fast Fourier transform method to analyze the excitation voltage, select the frequency domain of the excitation system to accomplish the fault diagnosis.%以WLZ型同步发电机励磁装置为实例,利用虚拟仪器软件Labwindows/CVI开发了一套励磁系统的状态监测的上位机应用程序.通过此应用程序完成了对WLZ型的各个状态的监测,程序中采用队列数据结构,充分利用上位机的内存缓冲完成了对系统的故障录波功能；同时,程序中采用快速傅里叶变换的方式对励磁电压进行分析,完成对励磁系统的故障诊断.
