500kV直流输电模型

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.)

说明：  空间信号的波达方向（Direction of Arrival，简称DOA）估计作为阵列信号处理研究的一个主要课题，在近些年来越来越得到大量的关注和研究。它可实现对空间中信源信号的准确的角度估计，实现信源方位等参数的具体精确检测，并且还具有很高的分辨力。这些特性使得DOA估计在声呐、通信及雷达等多种领域具有广阔的应用和发展前景。此程序为经典doa估计方法esprit算法。(direction of arrival,usually called DOA,has been an important subject recently.This program contains esprit)

说明：  python语言实现多项式秘密分享，并且可以用拉格朗日插值恢复(Python language implements polynomial secret sharing and can be restored by Lagrange interpolation)

说明：  鸽群优化(pigeon-inspired optimization,PIO)算法是近年来才出现的一种群体智能优化算法,它是受自然界中鸽群自主归巢行为的启发而提出的.(Pigeon inspired optimization (PIO) algorithm is a kind of swarm intelligence optimization algorithm which appears in recent years. It is inspired by pigeon homing behavior in nature)
