The complete-order modelling of state-space representations of synchronous and induction generators for wind turbine applications is presented. Fully equivalent models with different state variables, suitable for different control schemes, are given. The state-space representations provide a convenient, compact and elegant way to assess the induction and synchronous generator-based wind turbines,...
This paper observes the rotor angle stability phenomena. Initial simulations were made on a single machine infinite bus system, to model the influence of the synchronous generator, excitation system, stabilizer and the network layout. This is later applied to the model of the Croatian power system in the year 2016, when thermal power plant Plomin 3 should start its operation, based on the Croatian...
This paper discusses transient stability enhancement using Fault Current Limiter (FCL) and Thyristor Controlled Braking Resistor (TCBR). In the case of a severe fault occurrence in a power system, FCL is used for fault current limiting, transient stability enhancement and reduction of torsional oscillations, and TCBR is used for fast control of generator disturbances. The effect of these two instruments...
Analysis of stability is essential for power system planning and stable operation. The results of transient and steady-state stability studies depend on the appropriate choice of load models. This study investigates modeling issues of the induction motors that are used as a dynamic part of load models. Due to its superiority, we propose the application of the rotor speed frame based model of induction...
