绘制庞加莱截面图
在相空间中适当(要有利于观察系统的运动特征和变化,如截面不能与轨线相切,更不能包含轨线)选取一截面,在此截面上某一对共轭变量如x1和x.1取固定值,称此截面为Poincare截面,相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

主要用途是对抗多径衰落。由于多径衰落的存在,使得同一个帧由于路径不同,到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰,影响 性能。另外,由于有了循环前缀,使得IFFT FFT操作把原来的线性卷积变成循环卷积,大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

snake方法的主要局限性在于要求初始化要靠近期望的解和对边界的凹形部分的分割存在困难,GVF解决了这两个问题,并将其用于snake图像分割(The main limitation is the snake method requires initialization to be close to the desired solution and the boundary of the concave part of the division of the difficulty, GVF solve these two problems, and for the snake segmentation)

DC-ransmission
多端直流输电系统(multi-terminal DC,MTDC)为解决
大型风电基地功率外送的瓶颈问题提供了一个最佳解决方
案。研究了基于电压源换流器(voltage source converter,VSC)
的多端直流输电系统应用于大规模风电功率长距离外送时
的协调控制策略。通过构建一个四端系统连接两个大型风电
基地及本地电网向远方负荷中心进行功率输送,实现了风电
场的功率汇集和外送。仿真验证了该协调控制策略在大扰动
情况下,不仅能够提高VSC-MTDC系统潮流重新分配的能
力,而且可使风电场对直流网络提供一定功率支撑,增强了
电力系统动态稳定性
(Multi-terminal DC (MTDC) power transmission
system is regarded as the optimal solution scheme to sent out
power from large-scale wind farm. A coordinated control
strategy for voltage source converter (VSC) based MTDC
transmission system applied to long-distance power
transmission from large-scale wind farm is researched. By
means of constructing a four-terminal system connecting two
large-scale wind power bases with local power grid to send out
power to faraway load center, the wind power converging and
sending out by the proposed coordinated control strategy are
implemented. Simulation results show that the proposed
coordinated control strategy not only can improve the ability of
reallocating power flow in VSC-MTDC transmission system
under large disturbance, but also can make wind power base
providing a certain power support to DC transmission network,
thus the dynamic stability of power grid can be enhanced.
