摘要
为适应乡村小水电的绿色环保发展,在研究网侧及机侧控制算法模型的基础上,设计一种基于永磁同步电机的水力发电机控制系统,能够适应平流水发电水流变化、转速不稳定等外部环境的变化,提高发电机组的效率。通过设计一套37 kW的实验用发电机组及控制系统,在现场对相关功能进行了实验测试,验证了控制系统能够实现发电机宽转速、高效率的并网发电,满足平流水发电的现场实际控制要求。
To adapt to the green and environmental friendly development of rural small hydropower projects,a hydropower generator control system based on permanent magnet synchronous motor is designed with the analysis of the grid side and generator side control algorithm models.It can adapt to external environmental changes such as flow variation and unstable rotation speed,and can work in a wide range of rotation speed,thus improving the power generation efficiency.Then,a 37 kW experimental generator unit with control system is designed.Relevant functions of the system are tested on site.It verifies that the designed control system can realize a wide speed range and high efficiency power generation of the generator unit and fulfill the actual control requirements of horizontal flow power generation on site.
