摘要:
为实现微电网孤岛运行时负载功率能在各个逆变器间均衡分配,文章提出了一种基于MSOGI(多二阶广义积分器)谐波检测及自适应虚拟阻抗的控制方法,通过将无功、谐波及不平衡功率作为扰动注入到频率环中并对所产生的有功扰动进行积分,从而动态地调整基波正序、负序及典型次数谐波的虚拟阻抗。仿真和实验结果证明,该方法可在各线路阻抗不同且未知的情况下,使各分布式电源间的无功、谐波及不平衡功率达到精确均分。
Abstract:
In order to balance the load power sharing, adding virtual impedance is a simple and effective way. It proposed a new control method based on multiple second-order generalized integrator (MSOGI) harmonic detection and adaptive virtual impedance, which can dynamically adjust the virtual impedances of positive sequence fundamental, negative sequence fundamental and typical frequency harmonics by injecting frequency disturbance and integrating the deviation of active power. Simulation and experimental results show that the reactive power, harmonic power and unbalanced power between DG units can be equally shared even if the line impedance is unknown.
