基于W77E58单片机的光伏并网电站智能群控器设计

Design of the intelligent cluster controller for the grid-connected photovoltaic plant based on W77E58

研制了一种基于Winbond公司W77E58单片机的光伏并网电站智能群控器,该群控器由显示模块、通讯模块、时钟模块、报警模块以及大容量数据存储模块等构成。在现场可取代PC机,对多达60台的并网逆变器无人值守监控,具有成本低、安装灵活方便等优点;在大型分布多支路光伏并网电站中,多个智能群控器与PC机可组建多级分布式通讯网络,对整个光伏并网电站进行实时监控和管理。

Based on the single-chip computer W77E58 of the Winbond company, an intelligent cluster controller is developed for the gird-connected photovoltaic plant. The controller mainly consists of a display unit, a communication unit, a clock unit, an alarm unit and a data memory unit with big capacity. The cluster controller can monitor a maximum of 60 inverters in the locale of PV modules synchronously, which has many merits such as low cost and convenient installation. Furthermore, with the multi-level distributed communication network composed of cluster controllers and PC computers, the real-time supervision over the power plant is realized.
