Abstract When a high‐speed train approaches the insulated phase‐splitting section embedded between neighbouring power supply arms, vacuum circuit breaker (VCB) installed on trains must be disconnected to maintain traction system as no‐load condition for completing phase‐switching action, passes through depending its inertia. However, when operating VCBs, arc is easily triggered mobile contacts inside, accompanied by an overvoltage impulse. Herein, explore generating mechanism of inrush...
Due to the constant pursuit for higher operating velocity, traction power capacity high-speed trains needs be enlarged. When train passes approach insulating sections set between two neighbouring contact lines carrying current with different phases, vehicle-mounted vacuumed circuit breaker (VCB) switched off. Generally, arc may generate when connecting or separating contacts, switching on off VCB. In order investigate characteristics of reignition overvoltage 'train-rail-catenary' supply...
The 'train-rail' integrated grounding system for high-speed trains plays the critical role in providing unique path power feedback, which mainly consists of two parts - on-board dynamic sub-system and fixed terrestrial sub-system. can be classified into types modes – working provides discharging transferring traction power; while protective maintains reference ground potential train body both share rail as common current. Thus, current discharged from wheel sets flows through neighboring...
In recent years, energy issues have become more prominent. To solve problems, distributed power generation has received great attention. Therefore, also extensive attention and rapid development. This puts higher requirements on the quality of output inverter. How to control LCL type grid-connected inverter achieve goal better is a hot difficult point that needs be overcome in years.In this paper, simulation model established MATLAB/Simulink environment, advantages PI are analyzed, based...
Abstract This paper mainly actualizes the precise trajectory tracking for direct-drive servo system with undamped plant. Using nominal model of object in this is to realize control and obtain better effects by adopting ADRC strategy which introduced avoid overshoot causing design typical PID law improve robustness system. Simultaneously, it can also achieve fast convergence effects. Extensive simulations indicate that practically validates superiority these Both average placement error...
Distributed power sources have attracted much attention because of their small scale and cleanliness. The development smart grids based on distributed is also the trend world today. Therefore, this article great significance to construction distribution network model research stability model. This paper builds a basis SVPWM (Space Vector Pulse Width Modulation) algorithm, simulates process power, after delay setting changes demand inverter 3, it verifies that master-slave control in...
