摘要: Abstract The progress of Variable Speed Wind Turbine Systems (VS-WTS) is currently focused in reaching higher power ratings (8MW). Also, medium voltage operation at this level, particularly electrical network, a required feature. Consequently, high medium-voltage multilevel converters for VS-WTS have been attracting more and attentions. Nevertheless, most modern high-power consist large number Generators (WTGs) connected operating simultaneously to reach the multi-megawatt level. This study presents control strategy grid-connected onshore wind farm based Permanent Magnet Synchronous Generator (PMSG), where cascaded are employed on generators grid side. generator-side provide speed turbine-generator units implement Maximum Power Point Tracking. side Neutral diode Clamped (NPC) converter system regulates reactive real flow network. So, it dc bus ac power-factor. modulation technique proposed topology developed from Space Vector Modulation. overall approaches rectifiers an NPC also described. Nonlinear Sliding Mode (NL-SM) with Oriented Control developed. To validate approaches, simulations carried out energy conversion multi-level MATLAB/Simulink software. simulation results demonstrate good performance diverse scenarios.
