直流电机的闭环控制C语言代码.同行可以多多交流(Closed-loop DC motor control C language code. Peer may be more exchanges)

说明：  本例程通过matlab提供的simulink水轮机程序，做了改动，调整了部分参数，并且增加了借阅，模仿水轮发电机组一次调频过程，值得借鉴(Through the Simulink turbine program provided by matlab, the routine has been changed, some parameters have been adjusted, and borrowing has been added to imitate the primary frequency regulation process of the hydro-generator set. It is worth learning from.)

导纳矩阵自动计算程序,需要节点数据，支路数据，变压器数据等(Make admittance matrix node data, branch data, transformer data.)

说明：  这是一个多电平mmc的平均值模型，通过使用similink实现(This is a multi-level mmc average model by using similink)

简易的蓄电池与超级电容混合储能系统。可以观测SOC值变换，电压电流变化等(A simple battery and super capacitor hybrid energy storage system, can achieve SOC monitoring, voltage and current monitoring, contrast.)

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.)

说明：  热力系统中将水力模型与热力模型同时考虑，使用牛顿拉夫逊算法进行联合求解。(Hydraulic model and thermal model are considered simultaneously in the thermal system, and Newton Raphson algorithm is used to solve them jointly.)

在分析光伏发电原理与光伏电池数学模型的基础上，对由若干光伏阵列组成的大型光伏电站进行PSCAD仿真建模，并分析其运行特性。采用恒电压跟踪方法并利用不同温度下的测量制表值共同实现大规模光伏阵列的最大功率点跟踪(maximum powerpointtracking，MPPT)，并设计了相应的并网逆变器控制策略。最后，对大型光伏电站在正常运行以及站内外发生三相短路故障的情况进行仿真分析。(On the basis of analyzing the principle of photovoltaic generation and mathematical model of PCcells.)
