Individual‐phase decoupled P–Q control of three‐phase voltage source converter. Issue 11 (1st November 2013) - Fazeli, Seyed Mahdi
Abstract : Individual‐phase control has six control degrees of freedom: P ‐ and Q ‐control for each phase. The six control degrees are applied to a distribution static compensator (D‐STATCOM): (i) to support the AC voltages against voltage droop arising from weak transmission lines; (ii) to balance the active and reactive powers at the sending‐end although the three‐phase load is unbalanced; and (iii) to balance the voltages across the unbalanced load. A second contribution is a method to suppress DC voltage imbalance of D‐STATCOM capacitors caused by zero sequence transients. Proof of concept is by simulations. The simulation tool used is EMTDC‐PSAD.
