Transient Electromagnetic Torque Calculation Method for Short Circuit Fault of Turbo Generator Set

摘要

This paper presents a mathematical model of the fault component network for systems with series compensation devices, when the three-phase short circuit occurs. After the transient electromagnetic torque is calculated, the initial amplitude and attenuation coefficient of transient electromagnetic torque are derived. Based on the first standard model of IEEE, Simulation analysis have been done under the situation of different fault locations and whether the fault circuit contains series compensated capacitors. Simulation results are consistent with previous calculation results.
