Therefore ,the monitoring ofthe wind-driven generator and its monitoring holds greater practical significance. Inthis paper ,awhole set ofreal-time monitoring ofwind-driven generator scheme isdesigned and put into practice onthe basis ofanalyzing and studying the principle and application ofthe wind power. This design adopts the machine ofS7- use the voltage ,current and the temperature sensor for data gathering ,the GPRS wireless for data transmission. And the Kingview isadopted tomonitor three-phase voltage , three-phase current ,dc-bus voltage and temperature and torealize failure exception alerts, together with storing data record for data analysis. And finally prove the surveillance system iscapable ofeffectively monitoring the wind-driven generator. Keywords: wind-driven generator scheme, condition monitoring, PLC ,Kingview, GPRS 扬州大学本科生毕业设计 I 目录第一章绪论.................................................................................................................. 1 一、课题背景及研究意义................................................................................... 1 (一)、风能的利用及发展前景.................................................................... 1 (二)、国内外风力发电状况........................................................................ 1 (三)、风力发电的优势及存在问题............................................................ 1 二、风力发电系统的发展及现状...................
