摘要
对智能电网、清洁能源系统中存在的多种分布式系统进行了共性需求分析,针对分布式系统的工程技术特点,提出了一种基于点对点通信的新型分布式实时控制技术,通过点对点报文通信的方式实现了模拟量及开关量采集模块、出口控制模块和主处理器模块等环节的实时控制,满足了分布式系统对分散单元协同控制的工程应用需求。文中基于两种成熟的工业通信协议,针对两类分布式控制装置采用现场可编程逻辑门阵列(FPGA)对此技术进行了实现,并对装置进行了详细的测试与分析。两类典型装置已经在工程现场得到了试运行与推广,取得了良好的工程应用效果。
The demand of various distributed systems in the smart grid and clean energy field is analyzed in this paper. According to the engineering and technical characteristics of distributed systems in operation, a new real-time control technology based on point-to-point communication is proposed.Real-time control of the analog sampling module,input/output module and the main processor module is realized based on the point-to-point message communication,which can meet the engineering demand of the distributed system for joint control of scattered module units in different locations. The communication protocol is based on two industrial protocols, and field programmable gate array (FPGA) is used for implementation of the technology as well as detailed testing and analysis.The two kinds of typical devices have been trial run with good results.
