| 摘要:
分析了利用晶闸管进行软并网的原理;采用改进的小脑模型神经网络与比例积分微分并行控制方法对风力发电的异步发电机并网过渡过程进行了研究;利用Matlab/ Simulink平台建立了仿真控制模型。不同风速下风电机切入电网的仿真结果验证了文中所提出控制方案的正确性:采用该控制方案可将并网冲击电流控制在额定电流的2倍以内,且该软并网系统具有较好的稳定性、实时性。 | |||||||||||||||||||||||||||||||||||||

| Abstract:
The principle of soft cut-in system using thyristors is analyzed. By use of parallel control method of the improved cerebellar model articulation controller (CMAC) with proportion integral differential (PID), the transient process during the connection of induction wind power generators with power grid is researched. By means of Matlab/Simulink platform, a simulation control model is built. Simulation results of connecting wind power generators under various wind speeds verify the correctness of the proposed control scheme; using this control scheme the grid-connected impact current can be suppressed within two times of the rated current, and this soft cut-in system possesses better stability and real-time performance. | |||||||||||||||||||||||||||||||||||||
