Abstract： |
This invention relates to compensation control method for electric network at improper condition by using two type matrix inverter. It is characterized by that: setting two command values i(m) and i(+) under two phase rotating coordinate system to be constant value, and by using closed-loop control of output current to proceed real-time compensation to output line voltage space vector, and improve the wave-form of output current somewhat. Feed forward compensation control method is used, by real-time testnig of input voltage, calculating to obtain virtual dc voltage, proceeding real-time modification of output line voltage space vector regulating katio, the output voltage copmensation being achieved, with modification of output current wave-form. |
