Control Strategy of Direct-drive Permanent Magnet Synchronous Generators Wind Turbine Connected to Grid
摘要
Abstract
The control strategy of D-PMSG grid-connection was designed in order to save AC-DC-AC convenor and redu-ce initial investment costs. When the stator voltage and low-frequency bus voltage were satisfied on the condition of qu-asi-synchronization the AC-DC-AC converter was shorted in the main circuit by controlling the AC-DC-AC double PWM convertor. The generator stator was directly connected to box-type transformer. Then the low-frequency power energy was transmitted to back-to-back convertor station. The power energy was converted into 50 Hz AC and transmitted into grid. Two unit generators processes were simulated by PSCAD/EMTDC.the economic costs of control strategy were ana-lyzed. The results show that the control strategy is certainly feasible.关键词
