This paper describes the optimization of a PMSG wind turbine with an internal rectifier connected to a DC-DC converter (BOOST) and a resistive load. Firstly, an experimental validation of our wind turbine model is performed, and then some tests cases were conducted in order to deduce the MPPT control law. The simulation was performed using Matlab / Simulink tools, while the experimental implementation...
The present study attempts to model and simulate the power system of Sonabel, Burkina National Electricity Company under the flexible environment of Simpower System Tool box of Matlab/Simulink. The Burkina high-voltage transmission networks as well as its generation capacities are highlighted. Afterwards, the model has been validated by comparison simulation results with real grid data provided by...
This paper presents a model of the underground shielded cable by using voltage and current electrical measurements available in voltage source. The cable modeling is based on the distributed parameters theory which takes into account both core and sheath. This model is applied to the real case of 150 kV cable posed in trefoil configuration, connecting substations of TYNA, TAPAROURA and SIDIMANSOUR,...
In this paper an advanced simulation model of interior permanent magnet synchronous machine (IPMSM) is presented. The conventional dq-axis mathematical model is modified in order to include data derived from three-dimensional finite element analysis (FEA). Indirect interaction between FEA and circuit simulation enhances model fidelity embodying the influence of saturation and cross-coupling effects...
The analysis of transmission line under non-uniform incident field and with nonlinear loads is discussed in this paper. A test system is established according to IEC 61000-4-24, which consists of fast pulse generator and SPD (Surge Protection Device) test fixture. By using this system, the nonlinear Volt-Ampere characteristics of SPD can be measured and the nonlinear model of SPD is established. The...
