“…As described in [32], the PMSG model and MSC dynamics can be regarded as a first-order inertia link after inner-loop current feed-forward decoupling control and first-order tuning for the inner-loop current PI parameters, while the inertia delay of torque control can be adjusted by the PI parameters shown in Fig. 4(a).…”

This paper provides a systematic analysis of the large scale PMSG (permanent magnet synchronous generator)-based WECS (wind energy conversion system) torsional vibration problem under MPPT (maximum power point tracking) control and constant power control. This is from the perspective of SSO (sub-synchronous oscillation), SSH (sub-synchronous harmonics) and forced torsional vibration. The cause of SSO is the negative total system damping, weakened by the constant power control. The system is susceptible to inducing SSH in the grid current and voltage in the under-damped condition. To effectively suppress the torsional vibration of PMSG-based WECS, a stiffness compensation control strategy based on adaptive damping is proposed. The results show that SSO, SSH and the forced torsional vibration can be suppressed at the source using the proposed suppression strategy.

In this paper, a standalone permanent magnet synchronous generator (PMSG) system is designed to generate power at maximum power point (MPP). The variable speed operation of wind energy conversion system consists of PMSG, controlled rectifier and voltage source inverter co to the load. Proportional integral (PI), sliding mode (SM), and feed forward neural network (FFNN) control strategies are applied in field oriented control (FOC) at generator side converter. A comparative study on power generated at maximum power point (MPP) is done with these controllers using simulation. Hill climb search (HCS) method is applied to attain MPP. Load side inverter control strategy involves the PI and SM controllers in order to maintain the unity power factor and to control the active and reactive power for nonlinear load. The control strategies are modelled and simulated with MATLAB/Simulink. The effectiveness of proposed control method is demonstrated using simulation results.

Pengoperasian turbin angin terbagi atas beberapa zona operasi dengan tujuan untuk memaksimalkan kinerja turbin angin dan melindungi bilah turbin dari kerusakan saat diterpa oleh angin berkecepatan tinggi. Pembagian zona didasarkan pada besarnya kecepatan angin. Jika kecepatan angin berada diantara kecepatan nominal dan kecepatan cut out, maka turbin angin dapat dioperasikan pada nilai daya nominalnya dengan cara mengatur sudut pitch bilah turbin angin sedemikian rupa sehingga turbin angin dapat menghasilkan daya nominal. Riset ini bertujuan menganalisis hubungan antara perubahan kecepatan angin dan sudut pitch bilah turbin angin untuk mendapatkan daya nominal generator sinkron 3 fasa. Metode riset dilakukan melalui pemodelan turbin angin dengan generator sinkron 3 fasa. Turbin angin dirancang memiliki kapasitas daya mekanik 34,7 kW untuk kecepatan nominal angin 8 m/s yang dapat menghasilkan daya listrik nominal 32,68 kW, 408 volt pada kecepatan generator 1500 rpm. Hasil riset memperlihatkan perubahan kecepatan angin antara 8 m/s sampai dengan 15 m/s dapat mempertahankan kecepatan dan daya nominal generator tersebut dengan mengatur sudut pitch bilah turbin antara 00 sampai dengan 26,9270.
