In this simulation, the DC voltage of the matrix converter is derived using a three-phase linear load as a sample. It shows that the voltage used by the three inverters and the average over the switching period are always the same. It also shows that when the load is constant, the DC current of the inverter is also constant.

In this simulation, the phase difference of the signals a, b, and c in the paper is changed to 0 in 0.1 seconds from the state where the phase is 90 degrees different from the input voltage. The input current phase is the same as the above signal. Since the output voltage gradually increases, it can be seen that the DC voltage of the matrix converter increases as the phases of a, b, and c become closer to the input voltage phase. Strictly speaking, it is proportional to cosθ as described in the paper.

This paper proposed an optimized zero-state replacement (ZSR) method for general Bi-tri logic SPWM (BTSPWM) to deal with the common-mode voltage (CMV) issue. The BTSPWM can take advantage of the well-developed modulation strategies adopted in voltage source converters (VSCs) and transfer them into a current source converter (CSC) system through logic translation, which shares more general features compared with other modulations developed for CSC.

DC-link dynamic is one of the most important issues for current source converters (CSC). In practice, the dc-link voltage suffers from the slow dynamic due to grid disturbances, which will affect the quality of output waveform and damage the converter. Many solutions have been presented to cope with it, but none of them achieve the zero dynamic dc-link voltage control. In order to fill the technical gap, a novel solution is proposed in this paper.

This data-set consists of 3-phase differential currents of internal faults and 4 other transients cases for Phase Angle Regulators (PAR). The transients other than faults include magnetizing inrush, sympathetic inrush, external faults with CT saturation, and overexcitation conditions. PSCAD/EMTDC software is used for simulation of the internal faults and the transients.

Instructions: 

The files - ’fault_location_pha’, ’fault_location_phb’, and ’fault_location_phc’ have phase a,b,c differential currents for 46872 cases. Each row has 167 samples (one cycle). In fault_location_target’- the first 33480 are faults in series unit, next 13392 are faults in exciting unit. The files - ’transients_pha’, ’transients_phb’, and ’transients_phc’ have phase a,b,c differential currents for 13680 cases. Each row has 167 samples (one cycle). In fault_transient_target’- the first 720 - overexcitation, next 2520 - magnetizing inrush, next 2520 -sympathetic inrush, and next 7920 are external faults.
