风力发电系统故障建模与仿真
摘要:随着风力发电机安装量在全球范围内的急剧增加，对风力发电系统运行稳定性的要求也随之提高，对风力发电系统进行故障检测和容错控制也变得尤为重要。以2 MW风力发电系统为背景，首先建立风力发电系统动态模型；为更准确地模拟故障的影响，对系统进行比例－积分－微分(proportional integral derivative，PID)变桨距控制，在此基础上对风力发电系统的传感器故障和执行器故障进行模拟。结果显示，系统能较好地模拟各种故障，为下一步的故障诊断和容错控制打下了基础。
Abstract：With the global rapid growth of installed capacity for wind turbines, the operational stability requirements for wind turbine generator systems have increased. At the same time, fault diagnosis and fault-tolerant control of wind turbine generator systems have become particularly important. In this paper, a dynamic model of 2 MW wind power generation system is established. In order to more accurately simulate the impact of faults, proportional integral derivative (PID) pitch control is carried out. On this basis, the sensor faults and actuator faults of wind turbine generator systems are simulated. The results show that the system can simulate various faults and lay a foundation for fault diagnosis and fault-tolerant control in the next step.
