Digital-baseband-system
数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。
采样判决后的码型。
2、眼图（采样判决之前的眼图）（信噪比大眼图清晰）
3、误码曲线，（横坐标时信噪比，纵坐标时误码率）
4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum.
Sampling pattern after the verdict.
2, the eye diagram (eye before sampling decision) (SNR big eye clear)
3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis)
4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

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.
