| Abstract |
In this paper, a high speed frequency detection method
for the single phase utility interactive inverter is proposed.
Distributed power system is considered as a solution of the environmental
problems. As the distributed power system spreads, the
stability and the reliability of the utility interactive system becomes
important. In the utility interactive system, it is necessary to synchronize
to a utility voltage. In the case of a single phase system,
it is dificult to detect the instantaneous phase angle of the voltage
not same as the 3 phase system.
This paper describes a new highspeed frequency detection method
using quasi dq transformation. Quasi dq transformation is applied
to construct the PLL control with multi sampling parallel processing
method based on the FPGA implementation. Evaluations and
hardware implementations are described with simulations and experiments. |
