说明：  电力系统中短路故障导致的电压暂降的理想波形输出模型(Ideal output model of voltage sag caused by short circuit fault in power system)

说明：  先dq变换然后构建电压外环电流内环的双闭环系统，实现了statcom的前馈解耦控制。可以解决大负载投入的电压降落问题。(First, dq transform is used to construct the double closed-loop system of voltage outer loop and current inner loop, which realizes the feedforward decoupling control of STATCOM. It can solve the voltage drop problem of large load input.)

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分解求解。(Hydraulic model and thermal model are considered simultaneously in the thermal system, and Newton Raphson algorithm is used to solve them.)

内点法计算14节点系统最优潮流，目标函数为燃料费用最小(Optimal power flow of a 14-node system by using interior point method)

说明：  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：  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：  实现了以输出电压及其一阶导数为状态变量的无差拍控制的仿真(Realized by the output voltage and its first order derivative of state variable simulation of deadbeat control)

以IEEE33节点为例，考虑到配电网多为辐射性结构，选用前推回代法， 前推功率，回代电压，该算法通用性强(Taking the IEEE33 node as an example, considering that the distribution network is mostly radiative structure, the forward and backward substitution method is adopted, and the power is pushed forward and the voltage is replaced. This algorithm is universal.)

说明：  可借鉴用于基于Simplorer的多场耦合永磁同步电机SVPWM整理仿真。(It can be used for SVPWM finishing simulation of multi-field coupled permanent magnet synchronous motor based on Simpler.)
