江苏645规约重合闸断路器控制器 模拟主站通讯(Jiangsu 645 Protocol Simulated Main Station)

说明：  对电力系统进行交流潮流计算，计算方法为极坐标系下的牛顿拉夫逊法。(The AC power flow of power system is calculated by Newton Raphson method in polar coordinate system.)

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.)

可实现ieee30节点编号的优化，以及利用稀疏技术存储(It can optimize IEEE 30 node number and store it with sparse technology)

基于SOGI（2阶广义积分器）的单相锁相环simulink仿真，参考《光伏与风力发电系统并网变换器》周克亮译 71页(Based on SOGI (2-order generalized integrator) single-phase phase-locked loop simulink simulation, refer to Grid Converters for Photovoltaic and Wind Power Systems translated by Zhou Keliang ,page 71)

自己搭建的继电保护中的变压器比率制动保护模型，对研究变压器的保护有一定的参考价值(Build their own protection transformer protection ratio brake model, transformers for protection of some reference value)

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)

说明：  电流型两电平整流器simlink仿真，空间矢量调制，双闭环(SIMLINK simulation of current-source two-level converter)

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.)
