With the energy crisis,climate warming,environmental pollution and other issues becoming increasingly serious,the development of distributed clean energy has become a national policy. In the PV Station project,the communication problem between different types of photovoltaic (PV) inverter and PV master station is talked.First,various types of communication protocols used by photovoltaic (PV) inverters are analyzed and a set of algorithm for automatically analyzing the communication protocol of PV inverter is constructed.Then a kind of intelligent matching technology based on PV inverter communication protocol is developed and it is proved to be effective with a large number of engineering practices.With the technology,the protocol analyzed can be directly switched on,the new protocol can be quickly switched on and the debugging of on-site devices switched on can be directly carried out etc.%随着能源危机、气候变暖、环境污染等问题日益严重,发展分布式清洁能源已经成为一项国策;大量企业采用基于RS485、RS232等通信接口的Modbus协议作为一种通用工业标准在光伏逆变器等电站设备中作为数字化通信标准,针对不同厂家、不同型号的光伏逆变器与光伏主站之间存在多种协议规约需要主动适配的工程问题,通过对不同厂家、不同型号的光伏逆变器所涉及各种类型通信协议的深入分析和大量工程应用实践,提出了一种用于自动解析光伏逆变器通信协议的算法模型,并基于此模型研发了一种基于光伏逆变器通信协议的智能匹配技术,有效解决了不同类型光伏逆变器与光伏主站的通信问题;经过工程应用验证表明,应用该技术可以实现已解析协议的快速接入、新接入协议的快速解析匹配和已接入设备的现场调试等功能.
