摘要
为了实现分布式电源的高效、可靠和安全运行,文中介绍了一种基于电能质量监测的分布式电源自监测逆变器设计。这种自监测逆变器通过对分布式电源工作模式的监测以及输出电能的测量实现对闭环控制器反馈信号的优化,从而实现分布式电源在暂态和稳态上均能够跟随微电网控制中心的控制信号,并输出符合电网规范的电能。实验结果表明,该自监测逆变器能够应用于不同类型的分布式电源,使其在并网模式和孤岛模式下均能够稳定输出电能。
In order to realize the efficient,reliable and safe operation of distributed power supply,a distributed power self-monitoring inverter design based on power quality monitoring is proposed.The self-monitoring inverter optimizes the feedback signal of the closed-loop controller by monitoring the working mode of the distributed power source and measuring the output power,so that the distributed power source can follow the micro-grid control center in both transient and steady state.Control signals and output electrical energy in accordance with grid specifications.The experimental results show that the self-monitoring inverter can be applied to different types of distributed power sources,so that it can stably output power in both the grid-connected mode and the island mode.
