Impact Analysis of Time-Delay and Data Dropout on Three-Phase Inverter Parallel Operation with Networked Control

In this paper, a kind of networked control of power-sharing for inverter parallel operation is presented. To increase the participation of communication and improve the system performance, both autonomous mode and master-slave of communication mode in networked control are investigated. Nevertheless, communication actions may bring some unpredictable outcome due to the negative factors such as time-delay and data dropouts during the transmission. The theoretical and experimental methods are proposed to investigate the impact of these factors on system stability and performance. The experimental results show that the networked control proposed in this paper has strong robustness against the disturbances inherently exists in communications.
