[行业发展研究] Rayleigh-Mie-lidar-

本文介绍了用来测量对流层温度垂直分布的基于高光谱分辨率雷达技术的瑞利-米激光雷达系统(激光是对人眼安全的355nm波长的紫外线)。在该系统中,用两个法布里-珀罗标准具滤波器对影响大气温度的两个瑞利信号进行过滤。这些滤波器放在瑞利散射频谱的同一侧,并带有双端口光学输出通道。这种配置对米氏散射能获得较高的抑制比以及合理的瑞利散射透光率。米氏信号用第三个位于激光频率中间位置的法布里-珀罗标准具滤波器进行检测。这三个滤波器的参数是经过数值计算优化了的。实验结果表明,对于这两个瑞利通道都能实现-45dB的米散射抑制和大于1 的瑞利透光率。文中还介绍了一种用于校正气溶胶散射实验中所测得的温度(受到气溶胶和云的影响)的方法。初步试验和仿真证明,该设备中的双通道标准具和米散射校正在实际应用中有较高的性能。
A Rayleigh–Mie-scattering lidar system at an eye-safe 355nm ultraviolet wavelength that is based on a high-spectral-resolution lidar technique is demonstrated for measuring the vertical temperature profile of the troposphere. Two Rayleigh signals, which determine the atmospheric temperature, are filtered with two Fabry–Perot etalon filters. The filters are located on the same side of the wings of the Rayleighscattering spectrum and are optically constructed with a dual-pass optical layout. This configuration achieves a high rejection rate for Mie scattering and reasonable transmission for Rayleigh scattering. The Mie signal is detected with a third Fabry–Perot etalon filter, which is centered at the laser frequency. The filter parameters were optimized by numerical calculation。 (2012-10-19, PDF, 373KB, 下载27次)

[行业发展研究] 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. (2012-03-01, PDF, 201KB, 下载107次)
