Goal and objectives of the project | Researching, designing and manufacturing distributed grid inverter with high efficiency, stable working and low harmonic. |
Main results | - Theoretical results:
+ Proposal to apply SVPWM spatial vector pulse width modulation algorithm. This approach creates a new direction to solve the problems for the converter under pressure conditions on DC capacitors. Proposed space vector pulse width modulation algorithm experimentally tested on DSP-F28335 and DSpace-1103 hardware
+ The simulation and experimental results from the model have met the technical requirements of grid inverters (compared, refer to IEEE Std.519-1992 and Circular 30/2019 / TT- BCT).
+ Registered products are complete.
- Applied results:
+ Complete the design of a three-phase low voltage distribution grid inverter; supply to civil loads with a capacity of up to 5kW. Product performance> 90%, THD <5%.
+ It can be applied widely for Power companies and industrial production companies in construction investment. |
Novelty and actuality and scientific meaningfulness of the results | Design a 3-phase automatic grid controller of solar power up to 5 kW. The system operates thanks to the control algorithm, automatic stabilization and control the current pumped into the grid with the Q power always at a very low level (the power factor is always from 0.98 to nearly 1) even when the voltage, grid frequency applied to the inverter changes. |
