Abstract
We propose a local power network system by using solar power generation system installed individually. The power network system can be constructed only by connecting the controlled outputs of individual inverter systems. The individual inverter in this system is operated by a frequency-tracking scheme not by a phase control one based on the common synchronous signal. The inverter system can feed the electric power to the common network line in accordance with the individual power capacity. Moreover, the inverter circuit can be easily constructed only by using a three phase inverter module as proposed before.
The features of the proposed power network system are as follows; 1) simple circuit configurations, 2) power balance control, 3) maintenance free system, 4) easy extension 5) multifunctional control system and so on.
In this paper, we investigate the control scheme to obtain the above requirements. We show the inverter control system by using a frequency-tracking scheme. Then, we analyze the relationship of the system. Some simulation and experimental results are shown to verify the system operation.
