Study-of-VSC-HVDC-Controller-
风电潮流的波动会引起并网系统公共连接点(PCC)电压的波动。在基于电压源换流
器的高压直流输电(VSC-HVDC)交直流混合风电场并网系统中,控制VSC-HVDC 送端站注入
到PCC 点的无功功率可以抑制电压波动。本文讨论了VSC-HVDC 的无功功率控制器和定电压控制
器抑制电压波动的原理。基于电磁暂态软件PSCAD/EMTDC 建立了并网风电场模型、VSC-HVDC
模型及控制系统模型。仿真结果表明VSC-HVDC 采用定电压控制器的并网系统能更好的抑制电
压波动,采用无功功率控制器的系统具有较好的风电场并网性能。(Reactive power variation of integration wind farm may cause point of common
coupling (PCC) voltage fluctuation. In hybrid wind farm integration system based on HVDC of
voltage source converter (VSC-HVDC), the voltage fluctuation can be alleviated by compensating
reactive power to PCC from VSC-HVDC sending end. Therefore, the reactive power controller and the
stable voltage controller to alleviate voltage fluctuation are studied in the paper. The integration wind
farm, VSC-HVDC and their controller models are set up by PSCAD/EMTDC. The simulation results
show that the integration system adopted stable voltage controller has a better performance to alleviate
voltage fluctuation. However the system adopted reactive controller has a good wind farm integration
capability.)

Real-time-detection-of-negative
同相牵引供电系统旨在实现电能质量的综合补偿。提出了一种基于同步坐标变换的电流检测方法,能实时准确地检测
出负载电流的基波正序有功分量、基波正序无功分量、基波负序分量以及谐波分量,为综合补偿提供了基础。电能质量的补

real-timely into fundamental positive-sequence active component,fundamental positive-sequence reactive component,fundamental
negative-sequence component and harmonic component,which lays a foundation for comprehensive compensation.There are
nonlinear relation between compensation strength of power quality and device capacity.The paper proposes the concept of
compensation degree and gives the relationship between compensation degree and power quality parameters.By giving expected
power quality parameters,it adjusts compensation ratios of negative,reactive and harmonics instantaneously,so that the IPFC
capacity can be allocated between power quality compensating parameters optimally and real-timely,thus achieving capacity optimal
