This paper presents the Co-Simulation of a Small Wind Turbine (SWT) with Permanent Magnet Synchronous Generator (PMSG). It combines Simulink, Maxwell and Simplorer software’s to show the electrical machine behaviour connected with the power electronics’ circuit. To the control of the system the Maximum Power Point Tracking (MPPT) algorithm is used. The finite element analysis (FEA) was used to design the novel electrical machine with permanent magnets. Application of FEA method for PMSG modelling guarantee exhibit a more accurate behaviour over simplified Simulink models, also during motor and power electronics faults.

W artykule przedstawiono zagadnienie symulacji małej turbiny wiatrowej z generatorem synchronicznym z magnesami trwałymi (PMSG) przy wykorzystaniu trzech niezależnych środowisk programistycznych (tzw. współsymulacja). Podczas analizy wykorzystano wspólne obliczenia z programów Simulink, Maxwell i Simplorer. Model generatora wykonany został w środowisku Maxwell (z wykorzystaniem metody elementów skończonych (FEM)), co pozwala na jego dokładną analizę zarówno w stanach statycznych jak i dynamicznych. Układ energoelektroniki zamodelowano w programie Simplorer a układy sterowania (przy wykorzystaniu metody MPPT) w środowisku Simulink. Taka analiza pozwala na uzyskanie dokładnych rezyltatów w różnych warunkach pracy – w tym podczas uszkodzenia maszyny lub elementów energoelektroniki.

Electrical machines and electrical drives are modelled using different software. Most of them assumed that models of electrical machines are linear  or only the magnetizing characteristic is taken into account . These methods are good for simple well - known electrical drives . For new concept of electrical machines, the methods based on the FEA (Finite Element Analysis) should be adopted. The main disadvantage of that approach is long computational time. In recent years the computational power increase along with the advancements in the coupling methods between different software calculations, namely co-simulation , has leaded to the development of better models of complex systems which include multiphysics’ dynamics. One such a system is the wind turbine (WT), which has gained notoriety at different scales for specific applications. One of the issues that requires exact calculations is the research related to small wind turbines (SWT). A SWT is normally used as a standalone system or in water pumping applications . These small wind turbines (power less than 200 kW) are dominated by the use of permanent magnet synchronous generators (PMSG) , this is mainly because the lack of external excitation or additional energy input at starting and low speeds. The co-simulation approach has been used in the design and analysis of complex machines like doubly salient permanent magnet (DSPM) motor for fault tolerance analysis (short circuit and open circuit phase) , also for the five-phase dual-rotor PMSM , in the design of standalone micro hydro 4 kW PMSG , for the fault analysis of permanent magnet motor, such as inter-turn short circuit faults , , in the induction motor (IM) for the analysis of broken rotor bar , in the analysis of core losses of the brushless DC motor (BLDCM)  and also in the design and fault analysis of a 120 kW PMSG for wind turbines  and in the interturn shor [...]
