分布式电源即插即用接入装置的研究及应用

Application and Research of a Plug and Play Access Device for Distributed Generation

研制光伏发电即插即用一体化装置,该装置安装于分布式光伏发电与电网公共连接点接口处,集逆变装置、计量装置、保护装置、滤波装置、通信模块于一体,采用载波、WIFI等通信方式,实现与智慧家庭网络进行交互,实现发电电量信息、身份认证、电量计费等信息的传输。装置基于非侵入式电力负荷监测与分解技术,在非侵入状态下可以分析得到负荷集群中分布式电源出力的运行情况等信息。

This paper introduces the development of a plug and play integrated PV generator control and measure system,which is deployed between the PV generation site and the point of common coupling in power grid. The system integrates the power inverter, measurement, protection and wave filter sys-tems with the communication module. Through power line carrier signaling or WIFI communication the system makes power generation, ID verification and billing information dis-playable and operable on the smart home network. The system analyzes and gives the operation information of the distributed power generators in load clusters at non-intrusion situation by using non-intrusive power load monitoring and decomposition method.
