逆变器具有灵活、高效的特点，是新能源并网的主要接口。当多个逆变器连接到电网的同一个公共连接点时，逆变器非理想的电源特性，使得逆变器之间、逆变器与电网之间存在的谐波交互作用可能引发谐振， 使系统出现过电压、 过电流现象影响电网的电能质量，甚至威胁系统的安全稳定运行(Inverter is flexible and efficient, and it is the main interface of new energy integration. When multiple inverters are connected to the same common connection point of the power grid, the inverter is not ideal. The harmonic interaction between the inverters, the inverter and the grid may cause resonance, which causes the overvoltage and overcurrent to affect the power quality of the power grid and even threatens the safety of the system. stable operation)

说明： 模型以永磁直驱同步发电机组为研究对象，对包括风力机、发电机及其控制系统等各部分进行控制建模与仿真，接着通过坐标变换，分析并网逆变器在d／q坐标系下的模型，采用基于d轴电网电压定向矢量控制，并通过前馈补偿，实现有功、无功的解藕独立控制.(The model takes the permanent magnet direct drive synchronous generator set as the research object, and carries on the control modeling and simulation to each part, including wind turbine, generator and its control system, and then analyzes the model of grid-connected inverter in d coordinate system through coordinate transformation. The voltage oriented vector control based on d-axis power network and feedforward compensation are adopted to realize the decoupling independent control of active and reactive power.)
