Summary: This article investigates the application of a novel automatic segmented HHT method for evaluating the SEC of the voltage sag caused by different types of faults in the electrical networks. Factors such as fault types, location, X/R ratio, transformer and load connections, and POW were studied for their influence on the parameters of the voltage sag. The simulation results and tests with real data validate the effectiveness of the SHHT method in evaluating the SEC of the voltage sag in comparison to traditional methods.

Summary: This study proposes a speed control strategy for rotor field-oriented induction motor during input supply voltage sag, aiming to maintain torque and speed constant. By solving voltage, current, and torque constraints in the current plane, reference current commands are obtained to ensure the motor delivers load torque with reduced speed during voltage sag. Mathematical equations explaining current trajectory, voltage sag limit, and settling speed are derived for analysis and control implementation in MATLAB/Simulink.

Summary: This study proposes a method to evaluate bus and grid structure to alleviate voltage sags and swells on sensitive loads. By establishing voltage ellipse parameters and voltage matrix, defining key indicators and vulnerability indicators, and proposing a bus sorting method, a theoretical guidance is provided to mitigate voltage sags and swells. The experiment results show that the indicators facilitate the selection of access points for newly-added sensitive loads.

Summary: An immunity assessment method for the assembly line process is proposed in this study, fully considering the relationship between logistics line and power line, and thoroughly portraying the relationship between equipment and its links to evaluate the immunity of the whole manufacturing process. The results show that the deviation of the evaluation obtained by the proposed method is relatively small, indicating an accurate evaluation of the process immunity.
