Abstract: In view of the monitoring and intelligent switching of "three-electricity" power supply among wind power supply, photovoltaic power supply and municipal power supply, it is the advanced technology of new energy application to achieve the "three-electricity" effective and seamless power supply mode. Based on the Internet of Things technology to automatically complete the monitoring of important parameters in the power supply environment, remote transmission of data, data display and remote control to achieve the "three-electricity" integration function, effectively solve the "three-electricity" in the integration of a number of common problems. When the wind and photovoltaic power generation can not meet the requirements of power supply, it can automatically cut into the power supply to ensure the normal operation of the power load, which has a certain practical significance and practical value.

1 概述
所謂“三电”是风力发电供电、光伏发电供电以及市电供电。在风光发电应用系统中,风力及光伏发电受环境及气候影响很大,影响供电的稳定性及质量。采用“三电”合一的供电方式,在风力及光伏发电不能满足供电要求时,能自动切入市电供电,从而保证用电负载的正常工作。
2 系统组成方案
本套“三电”供电监测、智能控制系统是依托现在流行的物联网技术利用无线自组传感器网对采集的数据进行实时远程传输以及做出相应操作,提高系统的可靠性。
在“三电”供电监控、管理系统中,对温湿度、光照、交流电压等参数是影响底层模块运行状态的关键性因素,如何准确实时全面地监测这些环境变量的变化情况是提高“三电”智能切换准确度,提升居民(工作者)舒适度,保证居民(工作者)用电稳定的前提条件和重要环节。……
