摘　　要：风光互补发电受天气影响严重,具有一定的间歇性和不稳定型。为了能更好的满足电网安全性和稳定性的需求,风光储互补发电的形式能更好的弥补天气的不稳定性。为了促进风光储能互补发电控制技术的交流和发展,以全国职业院校技能大赛光伏电子工程的设计与实施赛项的设备作为主体,以新能源微电网为原型,根据风光储互补发电和微电网的控制要求,列出PLC的输入输出配置,并根据任务要求给出了编程的整体思路。和常规的梯形图编程相比较,本文采用C语言功能块的方式编程,使得程序占据PLC的内存由21%降到13%,且运行更稳定。The wind solar hybrid power generation is still seriously affected by the weather, with a certain degree of intermittence and instability. In order to meet the needs of grid security and stability better, wind-solar-battery hybrid power generation can compensate for weather instability.In order to promote the exchange of ideas and development of the control technology in wind-solar-battery hybrid power system, one of the equipments of the national vocational students’ skills competition named the design and implementation of photovoltaic electronic engineering is used with the prototype of microgrid new energy station. According to the control requirements of wind-solar-battery hybrid power system, the configurations of input and output ports of PLC are listed, and a general idea of the programming process is provided on the basis of the task. Compared to the regular PLC ladder diagram, this paper uses the C language function block which reduces the memory usage from 21% to 13%, which makes the system more stable and reliable.
