Micro-grid is a kind of new organization and structure of distributed energy, It integrates the advantages of distributed generation and weakens the adverse impact of the distributed generation on the grid. It makes the distributed power generation units, power grid and the end users to be connected as a whole, so the structure and configuration can be optimized easily. At the same time, the operation...
In recent years, with the rapid development of solar energy and other renewable energy, PV grid connected power generation technology has more and more attention. Grid connected inverter is the core of grid connected power system. When grid connected inverter operated in grid, the current control mode is essentially a voltage source input and current source output of the inverter. At present, a lot...
For acquiring of better quality and reducing the harmonic of the high frequency link matrix inverter-HFLMI output, a new envelope curve modulation method is discussed. The method can make the cycle duty of the front stage circuit of the HFLMI's driving signals variable and the HFLMI can gain better output voltage and current by working with de-re -coupling SPWM modulation. The carrier wave for front...
After the working principle and states of a new type of single-phase differential single-stage inverter based on classic BOOST DC/DC converters being analyzed, a topology family of single-phase and three-phase single-stage inverters are be concluded and be brought forward as a “BOOK” inverter name in the same differential working idea. The mathematical characteristics of single-phase and three-phase...
This paper discusses vector modulation and sliding mode control for a kind of high frequency link matrix inverter (HFLMC), and presents a kind of De-Re-couple analysis idea to the HFLMC. The De-Re-couple vector condition also has been induced Especially aiming at its non-linear characteristic, this paper proposes a new control strategy called De-Re-couple vector modulation slide mode control and summarized...
An energy-saving AC variable frequency speed-governing experiment system, based on the structure of two motors at the same shaft realized by DSP control, is introduced in this paper, which controls motor set at the same shaft run on different frequency and realizes variable frequency speed-governing of little load power-consumption based on the regenerate power feedback of motor group. Combining with...
