Abstract:

Regenerative drives with 3- phase AC/DC Voltage Source Converters (VSC) at the front – grid side provide bi-directional power flow, low harmonic current distortion, unity power factor and fixed DC bus voltage. Thus, with these good features, regenerative drives with advancement of power electronics become very attractive solution in high performance applications requiring frequent acceleration and deceleration like elevator drives, cranes, servo drives etc.

The presentation will provide historic perspective and evolution of regenerative electric drives in industrial applications and transition of their three phase front end VSC into grid type of applications for alternative energy. The principle of operation of regenerative three phases AC/DC-VSC will be explained first. It will be followed with the derivation of mathematical models of a VSC in abc and αβ stationary reference frames. The stationary αβ model will be transferred to synchronous reference dq model convenient for derivation of control strategy. The cascaded control structure will be discussed and similarities of VSC control with vector control of electrical machines will be pointed out. Phase Lock Loop (PLL) system for synchronization and locking with the grid, as an essential part for reliable operation and stability, will be explained. Operation of VSC at increased grid voltage and criteria for section of the DC bus voltage will be discussed. The methodology for tuning voltage, current, PLL and “field weakening” regulators will be presented. The presentation will end up with the analysis and comments on practical issues facing the design and applications of 3 phase grid type inverters.
