摘要
基于离网风电-网电互补供电试验研究,设计了以计算机编程调制载荷的磁粉制动器加载装置,并在搭建的试验平台上,试验研究了加载装置模拟实际载荷特性,以及互补双电源向负载供电的切换控制技术.试验结果表明,加载装置的响应速度和加载精度可真实反映模拟实际载荷特性,互补双电源的切换控制技术可靠、稳定,提高了风能利用率.
Based on the experimental research on complementary supply system of off-grid wind power and grid power,this paper designs a magnetic brake loading device by computer programming for load modulation.Experimental platform is built to simulate the actual load characteristics of the loading device,as well as to develop the complementary dual power switching control technology for load power supply.The results show that response speed and load accuracy of the loading device can be a true reflection of the actual load characteristics,the complementary dual power switching control technology is reliable and stable,and it can improve the utilization of wind power.
