鲁棒下垂控制方法准确的比例负载分担逆变器并行操作
摘要:在本文中,传统的下垂控制方案的固有局限性显露出来。实践证明,并行操作逆变器应具有相同的每单位阻抗,以便他们能够在比其额定功率准确地分担负载,采用传统的下垂控制计划时。下垂控制器还应该产生相同的电压设定点的逆变器。两个条件都难以在实践中,这将导致成比例的负载分担的错误,以满足。一种改进的下垂控制器然后提出实现准确比例的负载分担而不满足这两个要求,以降低负载电压降由于负载效应和下垂的效果。负载电压可以保持围绕额定值所要求的范围之内。该战略是对数值误差,干扰,噪声,馈线阻抗参数漂移和组件不匹配的鲁棒性。唯一的共享错误,这是量化的文件,来自误差测量负载电压。当在测得的电压的误差,会出现电压降和共享准确性之间存在着根本的权衡。还已说明的是,为了避免在功率共享错误,额定电压和频率的全局设置应该是准确的。提供的实验结果验证了分析和设计。关键词:微电网,下垂控制逆变器并联运行,按比例分担的负载
