Improved Negative Sequence current Injection Balancing Method considering Zero Sequence Voltage for cascaded H-bridge STATCOM

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
Cascaded H-bridge STATCOM is widely adopted to regulate the power quality in power grid and industrial application. Considering the existence of zero-sequence voltage which cannot be neglected in the simulation model, this paper proposed an improved clustered voltage balancing strategy based on negative-sequence current injection.

Negative sequence current injection control algorithm compensating for unbalanced PCC voltage in medium voltage PMSG wind turbines

2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014
This paper proposes a control algorithm for permanent magnet synchronous generator with a back-to-back three-level neutral-point clamped voltage source converter in a medium-voltage offshore wind power system under unbalanced grid conditions. The proposed control algorithm particularly compensates for the unbalanced grid voltage at the point of common ...

Capacitor voltage balance performance comparison of MMC-STATCOM using NLC and PS-PWM strategies during negative sequence current injection

2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016
This paper addresses the modular multilevel converter applied as a static synchronous compensator. The main objective of this work is to compare the converter performance considering two different submodule capacitor voltage balancing strategies: nearest level control and phase-shifted pulse width modulation, during positive and negative sequence ...
