NewK-means-clustering-algorithm
说明： 珍藏版，可实现，新K均值聚类算法，分为如下几个步骤：
一、初始化聚类中心
1、根据具体问题，凭经验从样本集中选出C个比较合适的样本作为初始聚类中心。
2、用前C个样本作为初始聚类中心。
3、将全部样本随机地分成C类，计算每类的样本均值，将样本均值作为初始聚类中心。
二、初始聚类
1、按就近原则将样本归入各聚类中心所代表的类中。
2、取一样本，将其归入与其最近的聚类中心的那一类中，重新计算样本均值，更新聚类中心。然后取下一样本，重复操作，直至所有样本归入相应类中。
三、判断聚类是否合理
采用误差平方和准则函数判断聚类是否合理，不合理则修改分类。循环进行判断、修改直至达到算法终止条件。(NewK-means clustering algorithm ，Divided into the following several steps:
A, initialize clustering center
1, according to the specific problems, from samples with experience selected C a more appropriate focus the sample as the initial clustering center.
2, with former C a sample as the initial clustering center.
3, will all samples randomly divided into C, calculate the sample mean, each the sample mean as the initial clustering center.
Second, initial clustering
1, according to the sample into the nearest principle clustering center represents the class.
2, as this, take the its recent as clustering center of that category, recount the sample mean, update clustering center. And then taking off, as this, repeated operation until all samples into the corresponding class.
Three, judge clustering is reasonable
Adopt error squares principles function cluster analysis.after clustering whether reasonable, no reasonable criterion revisio)

power_HalfBridgeMMC
说明： 模块化多电平换流器(modular multilevelconverter MMC)已成为柔性直流输电系统的首选换流器拓扑。我国已建成的上海南汇柔性直流工程、南澳三端柔性直流工程、舟山五端柔性直流输电工程以及正在建设中的厦门柔性直流工程都采用MMC结构。国际上SIEMENS已建成的美国跨湾工程(Trans Bay Cable Project TBC)和法国一西班牙联网工程(INELFE工程))都采用MMC结构。同时，ABB公司提出了一种级联两电平结构(cascaded two level CTL)，其本质仍为MMC，并且ABB后续建设的数项柔性直流工程都采用CTL结构。因此，MMC已由最初的低压、小容量示范工程向高电压、大容量方向快速发展，展现出很好的发展前景。(Modular multilevel converter (MMC) was first proposed and patented by Professor R. Marquardt in 2001. It consists of several sub modules (SM) with the same structure. The sub module structure can be divided into three types: half H-bridge, full H-bridge and double clamp sub module. Modular multilevel converter (MMC) has shown a very important engineering application prospect.)
