通过采用双二阶广义积分器实现风力发电并网系统的锁相，检测出不对称电网电压中的正序分量和负序分量。因为电网频率比电网相角更加稳定，所以使用双二阶广义积分锁频环对风力发电系统进行并网。利用 MATLAB ／Simulink 软件对基于双广义二阶积分锁相环和锁频环的风力发电并网系统进行仿真，仿真结果证明锁频环比锁相环具有更加平滑的响应，验证了控制系统的可行性和有效型，保证了风力发电系统的顺利并网。

The double second-order generalized integrator is adopted to realize phase locking of the wind power integration system,and positive and negative sequence components of the asymmetric grid voltage are detected.As the frequency of the grid is more stable than its phase angle,the double second-order generalized integral frequency-locking loop is chosen for grid-connection of the wind power generation system.Matlab /simulink software is used to simulate the wind power integration system based on the double second-order generalized integral phase-locking loop and frequency-locking loop.The simulation results verify that the response of the frequency-locking loop is smoother than that of the phase-locking loop and that the control system is feasible and effective,ensuring the smooth integration of the wind power generation system.
