Multiport Railway Power Conditioner and Its Management Control Strategy With Renewable Energy Access
TL;DR: A multiport railway power conditioner with the renewable energy access is proposed to realize the on-site power consumption and negative-sequence compensation and its power-flow management strategy with five classic operation modes is proposed and analyzed.

Commutation Failure Mitigation Method Based on Imaginary Commutation Process
TL;DR: In this paper , the authors proposed an imaginary commutation process to simulate the actual execution of a commutation failure and calculated the imaginary extinction angle (EA) by comparing the imaginary supply voltage-time area and the imaginary demand voltage time area.
Operation Analysis and a Game Theoretic Approach to Dynamic Hybrid Compensator for the V/v Traction System
TL;DR: A two-level optimized hybrid controller is proposed to keep the power system affirmative for any train load attacks, and an optimized hybrid compensation can be realized.

A Damping-Controllable-Commutated Converter for Mitigating Commutation Failure of LCC-HVDC
TL;DR: A DCCC is proposed to enhance the CF mitigation capability of LCC-HVDC systems. It operates like the LCC in normal conditions and decomposes the commutation process into current-limiting and forced commutation processes under fault conditions. Simulations show that the DCCC can effectively enhance the CF mitigation capacity of the system.

Background characteristics and influence analysis of greenhouse gases at Akedala regional background station in Northern Xinjiang
TL;DR: Based on the weekly collected flask air samples at Akedala (AKD) Station in northern Xinjiang during 2009-2020, this article measured the concentrations of CO2, CH4 and CO and analyzed their long-term variation trend, seasonal characteristics and the influence mechanism of anthropogenic and long-range transport of greenhouse gases at the background station.
