摘　　要：根据能源需求和设备性能,为了优化能源生产和分配并确保新能源发电站能源供应稳定性与可靠性,设计基于模糊PID的新能源发电站设备自动控制系统。该系统构建水火电机组数学模型、太阳能机组数学模型和风电机组数学模型,运用以上数学模型获取不同类型新能源发电站设备运行状态数据后,利用该数据通过模糊PID控制器输出新能源发电站设备自动控制量,然后运用系统硬件控制电路,将自动控制量反馈给新能源发电站设备,实现其自动控制。实验结果表明,该系统可有效得到新能源发电站设备中调速器阀门位置变化量,实现风电机组内电机自动控制和无功功率自动控制,同时自动控制超调量较小。Based on energy demand and equipment performance,in order to optimize energy production and distribution and ensure the stability and reliability of energy supply in new energy power plants,a fuzzy PID based automatic control system for new energy power plant equipment is designed.The system constructs mathematical models for hydro thermal power units,solar power units,and wind turbines.After obtaining operational status data for different types of new energy power plant equipment,the PID controller outputs the automatic control quantity of new energy power plant equipment based on these parameters and fuzzy rules.Then,the system hardware control circuit is used to feedback the automatic control quantity to the new energy power plant equipment,achieving its automation control.The experimental results show that the system can effectively obtain the position change of the governor valve in the new energy power station equipment,realize the automatic control of the motor and reactive power in the wind turbine,and at the same time,the automatic control overshoot is small.
