大型风电场接入电网的稳定性问题研究,希望对大家有点启发( the problems of Large wind farms connected to the grid stability)

说明：  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.)

轴系扭转振动的matlab计算,将采集的脉冲信号转化成扭转角。(torsional vibration)

说明：  用牛顿法计算电力系统在级联故障下的潮流，对越限支路进行切除负荷。(Newton method is used to calculate the power flow of the power system under cascaded fault, and the load is cut off for the out of limit branch.)

说明：  MMC简化仿真模型,单端换流阀，采用PSCAD搭建了简化的MMC电路模型，用于研究MMC工作原理。(MMC simplified simulation model, single-end converter valve, using PSCAD to build a simplified MMC circuit model, used to study the working principle of MMC.)

异步电机速度、电流、磁链闭环控制，电流控制采取滞环控制，动态跟踪效果较好。(The closed-loop control of speed, current and flux of induction motor and hysteresis control of current control have good dynamic tracking effect.)

充电桩通信规约代码，根据国标进行编写，使用国内大部分电动充电车。(Charging pile communication protocol code, compiled according to national standards, using most domestic electric charging vehicles.)

说明：  采用PSCAD搭建了简化的换流阀不可控充电过程，并模拟了不同故障下的电路状态。(PSCAD is used to build a simplified uncontrolled charging process of the converter valve, and the circuit state under different faults is simulated.)

电力系统仿真建模需要的模型，可以适合智能电网，分布式发电(power system modeling control smart grid stability)

说明：  MMC逆变器子模块电容电压平衡策略控制算法与仿真模型(strategy and simulation of MMC inverter module capacitors voltage balance)
