Despite numerous advantages of space vector pulse width modulation (SVPWM) methods, their implementation on multilevel inverters (MLI) is onerous. Due to the ever-increasing use of MLIs in power electronic applications, it is essential to implement efficient modulation procedures aiming to keep control sampling periods sufficiently short. Here, a novel and straightforward SVPWM Strategy is introduced, which uses algebraic functions throughout the procedure and avoids using hardware-consuming trigonometric functions. Look-up tables and region detection are no more necessary.

Space vector pulse width modulation (SVPWM) is a superior switching technique offering several benefits for power electronic inverters. However, concerning multilevel inverters (MLIs), implementing SVPWM is a demanding and time-consuming task because it deals with the six sectors of the space vector modulation (SVM) plane and numerous regions and vectors. Several research works in the literature tried to simplify SVPWM implementation for MLIs.

This data set consists of 3-phase currents of faults and other transient cases for transmission lines connected with PV Farms. PSCAD/EMTDC software is used for the simulation of faults and other transients. Transmission lines connected to photovoltaic (PV) farm protection is crucial for ensuring reliable and safe operation. PV farms generate electricity from sunlight and feed it into the grid via transmission lines. However, factors such as fluctuations in solar irradiance, system faults, and grid instability can lead to voltage and current imbalances.
