compressor

用来设计和计算钻杆和接头的各个性能，具有一定的参考价值。(Used to design and calculate the drill pipe and joints of the various performance, with a certain reference value.)

说明：  simulink PMSM 三相逆变器电压单闭环控制，DC-AC-DC-AC(simulink PMSM DC-AC-DC-AC)

用拟牛顿法求非线性方程组 fi( x1, x2, ?, xn ) = 0, i = 1, 2, ?, n 的一组实数解。(A quasi-Newton method is used to find a set of real solutions of the nonlinear equations.)

包含电气工程专业新能源发电课程中的光伏模型和风电并网模型，能在matlab中正常运行。(Including photovoltaic models and wind power grid-connected models in the new energy generation course in electrical engineering, which can operate normally in matlab.)

说明：  simulink搭建的全桥整流+buck电路，实现AC到DC，然后DC到DC的变换，其中全桥为SPWM控制。(Simulink built a full bridge rectifier +buck circuit, AC to DC, and then DC to DC transform, in which the whole bridge is SPWM control.)

分别对速度、磁场两个分量进行独立控制。通过控制转子磁链，以转子磁通定向，然后分解定子电流而获得转矩和磁场两个分量，经坐标变换，实现正交或解耦控制(The velocity and magnetic field components are controlled independently. By controlling the rotor flux, the rotor flux is oriented, and then the stator current is decomposed to obtain two components of the torque and magnetic field. Orthogonal or decoupling control is realized by coordinate transformation.)

没有用，随便上传的，一会说必然会把握科技和室内的(An all-DC offshore wind farm with series-connected turbines)

说明：  c语言，电力系统潮流计算程序，通用，工程开发应用使用(power flow calculator)
