Abstract Emissions trading schemes (ETS) have spread across the globe to tackle climate change. However, limited attention has been given to how ETS characteristics and designs differ and why. We use the concept of institutional complementarity to explore how the EU ETS and South Korea's ETS (K‐ETS) adapt to complement established political economy ...

Abstract Internet trade is increasingly recognized as a dispersal pathway of non‐native plant species that is difficult to monitor. We sought to identify non‐native flora present in the Chinese online market, the largest e‐commerce market globally, and to decipher the effect of existing trade regulations, among other variables, on e‐trading patterns ...

准确评估风电场发电量水平对项目开发至关重要。针对海岸线附近的近海风电场,结合已建项目的测风塔数据和风电机组运行资料,得出WAsP计算模型主要参数取值。近海地区的风资源及发电量呈现一定的衰减规律,通过不同粗糙度和尾流衰减系数的设置,验证各方案模型电量与实际电量的拟合水平。结果表明,风电场的粗糙度取值要结合地形地貌、海洋水文条件等因素,海岸线附近近海风电场的粗糙度取值略高于软件推荐值,粗糙度水平为0~0.005 m;Park模型尾流衰减系数越小,发电量越小,不同的尾流衰减系数对发电量计算结果影响高达4.9%,

风力发电机遭受雷击时,塔筒内控制电缆、塔基处以及箱式变压器低/高压侧都会出现过电压,且过电压还会通过集电电缆和联合接地装置传到其他风电机组。为研究雷击风电场时引起的暂态电压,建立了包含风力发电机、集电电缆、箱式变压器的等效模型。考虑了雷电流参数、风力发电机接地电阻大小及风电场拓扑结构对风电场过电压影响。结果表明:单台风电机组遭受雷击的情况下,风电机组过电压值与雷电流幅值成正比,且波前时间为8.0μs和20.0μs时,雷电流幅值对控制电缆缆芯过电压影响很小;风电机组过电压值与波前时间成反比 ...
