In order to facilitate exchanging and sharing data between the domestic and international main tools for power system electromechanical transient analysis, this paper analyzes and compares the common mathematical models for transient stability including synchronous generator, excitation system, turbine and governor, load and even DC transmission system in PSD-BPA and PSS/E. Several typical problems...
This paper considers modeling and simulation study of a helicopter with an under-slung external load system. Mathematical models of a single main rotor helicopter and an under-slung load are presented in this paper. Considering the two models, a mathematical model for a helicopter carrying an under-slung load is obtained. The combined system model can be used for stability analysis and controller...
This paper deals with a modeling approach of an embarked electrical network. This network is composed of a synchronous generator feeding linear and non linear load. In order to simplify the identification of inaccessible part of the generator, a specific modeling approach of the machine is established. Thus, the rotor is modeled by generalized transfer functions. Its order is chosen to have the desired...
This paper proposes a modeling procedure of synchronous machine with admittance networks. Load and stator are modeled in a conventional way, i.e. in dq frame. The accent is given to inaccessible parts of the machine (rotor). Hence, the rotorpsilas circuit is modeled with admittance functions. The order of the system, which depends on the desired precision, does not modify the equations set. Parameters...
