A Predictive Control Strategy for Mitigation of Commutation Failure in LCC-Based HVDC Systems
IEEE transactions on power electronics, 2019 High-voltage direct-current (HVDC) systems are being widely employed in various applications because of their numerous advantages such as bulk power transmission, efficient long-distance transmission, and flexible power-flow control.

Harmonic analysis of AC-bus voltage in converter station based on time–frequency transformation
The Journal of Engineering, 2018 The disturbance of the AC system has become one of the main causes of commutation failure in the high voltage direct current (HVDC) transmission system. Here, the time–frequency transformation method is used to analyse the AC-bus voltage disturbance from

Translation Invariant States on Twisted Algebras on a Lattice
, 2009 We construct an algebra with twisted commutation relations and equip it with the shift. For appropriate irregularity of the non-local commutation relations we prove that the tracial state is the only translation-invariant ...

Two-step commutation control of switched reluctance motor based on PWM
The Journal of Engineering, 2019 Aiming at the noise suppression of switched reluctance machine (SRM), the two-step commutation control method is improved. Combining this with pulse width modulation (PWM), the optimisation problem of the switching angle is studied and analysed and given

Note on uncertainty relations in doubly special relativity and rainbow gravity
, 2015 We present commutation relations depending on the rainbow functions which are slightly different from the well-known results. However, the advantage of these new commutation relations are compatible with the calculation of the Hawking temperature in the ...
