Simulation Model and State Analysis of Ship Transmission Line

Polish Maritime Research, 2018
In order to discuss the simulation model of the ship transmission line and the state of the transmission line, an early fault model is built according to the evolution principle of the short circuit fault of the transmission line and combining with the ...

Short-circuit current calculation method for partial coupling transmission lines under different voltage levels

International Journal of Electrical Power & Energy Systems, 2016
Abstract In power system, there are partial coupling lines under different voltage level because of the development of power system. When faults occur on these lines, zero-sequence mutual impedances bring difficulty to short-circuit calculation. To solve the problem, a new method is proposed in this paper.
