内点法计算3节点系统最优潮流 3节点系统(Interior point method to calculate three-node system OPF 3-node system)

Kmeans聚类法 MATLAB实现 没有调用函数(Kmeans clustering method MATLAB implementation does not call the function)

白噪声是工程中常用到的参考信号，程序通过白噪声的计算方法，可以得出2至7阶的白噪声序列，值得参考(White noise is commonly used to project the reference signal, the program is calculated through the white noise, can be drawn from 2 to 7 bands of white noise sequence)

分别利用 Lagrange插值法、分段线性插值法与三次样条法进行插值逼近(Respectively, by Lagrange interpolation, piecewise linear interpolation and cubic spline interpolation approximation method)

晶闸管控制串联电阻在500kv电力系统的matlab仿真中的应用。(Modeling and simulation of 500kv power system.The theoretical ground and design realization of alternating current power lines of the new type- Controllable Flexible A.C. Transmission Systems (CFACTS) are considered. Earlier lines of such type had been known as Controlled Self- Compensating High Voltage Transmission Power Lines (CSHVL), as well as Controlled Compact Transmission Power Lines. The CFACTS design principles and the basic CFACTS design directions are implemented. The basic characteristics of CFACTS (500kV) which are studying have great prospects. CFACTS(10, 35, 110 kV) which already built and maintained. )
