Analysis and Suppression of Low-Frequency Oscillation Between EMUs and Traction Networks in High-speed Railways
This book focuses on the low-frequency oscillation between EMUs and traction networks in high-speed Railways. As the power source of high-speed trains, the traction network's power performance directly affects the safe and stable operation of the train. However, the low-frequency oscillation between EMUs and traction networks will fluctuate voltage or current, resulting in poor power quality, electrical device failure, and even interruption of traction power. Therefore, it is important to reveal the mechanism of low-frequency oscillation and propose suppression strategies. This book systematically shows the newest research results of analysis and suppression of low-frequency oscillation between EMUs and traction networks in high-speed railways, especially in the modeling methods of vehicle-grid systems and suppression strategies for low-frequency oscillation. These methods or strategies can provide important references and help for researchers, scholars, and engineers on traction power technology in high-speed railways. The main contents include the overview of low-frequency oscillation between EMUs and traction networks, the introduction of main modeling methods for vehicle-grid systems, especially single-phase rectifiers, the line-side converter control algorithms in vehicles for the suppression of low-frequency oscillation, the traction substation power compensation strategies for the suppression of low-frequency oscillation, etc.

Proceedings of the First Mandalika International Multi-Conference on Science and Engineering 2022, MIMSE 2022 (Mechanical and Electrical)
This is an open access book. The covid-19 pandemic today forces humans to do almost all activities from home. Consequently, inventions in many fields of engineering technology are needed to facilitate those activities. First, human activities mainly are based on information technology today and internet connection is very important. People generate, send, and receive data by their smartphones every time and everything is connected to the internet. Equipment becomes smarter to assist the owner. Second, People need powerful, efficient, and smart vehicles and machines in Industry 4.0. Third, the need for energy increases, which causes the decrease of global environmental quality. It needs new technology for saving energy by discovering new technologies in mechanical engineering. Fourth, many technologies emerge as disaster prevention by developing innovations in civil engineering and architecture. The Engineering Faculty of University of Mataram invites engineers and researchers around the world to visit Lombok island and to attend the valuable multi fields conference on science and engineering named “The First Mandalika International Multi-conference on Science and Engineering 2022′′ or “1st MIMSE 2022”. This fruitful event will be the annual conference in Lombok island which is supported by the West Nusa Tenggara Province government. Initially, the 1st MIMSE 2022 consisted of 5 engineering fields are Civil, Architecture, Electrical, Mechanical, and Informatics Engineering.
