9月份，受上年用电量基数高及经济波动等因素影响，全国全社会用电量增速现较上月回升，但仍为近18个月以来次低；重工业用电增速回升，与轻工业基本持平；制造业用电增速略有回升，四大高耗能行业用电拉动用电增长的作用仍然明显；城乡居民生活用电增速继续放缓。

9月份是煤炭消费的淡季，加上水电大发，电煤日耗下降，库存大幅增加。煤炭市场供应宽松的格局依然没有改变。

9月，电力设备制造业复苏态势趋缓：虽然除工业锅炉、电站水轮机、电力电缆外，大多数电力设备重点产品产量实现增长；但受下游需求下滑影响，大多数产品价格下滑，价格上涨的子行业减少；企业投资意愿和投资能力有所减弱，行业固定资产投资增速继续回落。

The bulk transfer of electrical energy from the point of generation to electrical substations is termed as electric transmission. Generally, this transmission occurs at very high voltage levels, in order to minimize losses. High Voltage Transmission Systems are made up of all the major equipment used to carry out the entire task of electric power transmission. They mainly comprise HVAC equipment that includes high-voltage switchgear and circuit breakers, FACTS, HVDC transmission equipment, submarine cables, and some parts of substation automation equipment and monitoring.

A detailed study of the geographical segmentation is presented in the report, and growth patterns are also provided.

针对共同承担下游防洪任务的梯级水库,建立了基于库容补偿的梯级水库汛限水位动态控制域计算方法;分别建立了上、下库有富余防洪库容情形下的防洪库容置换模型,并从防洪有利和蓄水有利角度建立了改变上库出库过程的调度策略;以滹沱河岗南-黄壁庄梯级水库为例,建立了有富余防洪库容的水库水位与关联库汛限水位抬升值之间的关系,取得了合理的结果。

建立了适应于结构网格的复杂边界浅水流动有限体积数学模型。基本控制方程采用对自由水面相对高度在水平向和垂直项进行分裂后形成的守恒性的修正二维浅水方程,在结构网格上采用中心型格式离散基本控制方程,采用能够有效捕捉激波的近似黎曼求解器HLLC计算界面通量,并使用坡度限制器重构界面两侧变量,利用MUSCL-Hancock在时间维上积分,使时空精度提升到二阶;分别采用中心差分格式和全隐式方法处理底坡项和阻力项,保证了模型稳定性。提出了局部修正底高和水位的干湿边界处理方法和基于B样条曲线的复杂边界处理方法,很好地处理了急变水流变化引起的干湿单元网格的动态交替和复杂边界处水流特性正确表达。最后通过算例证明了模型性能较好,具有推广价值。

A publication of recent energy statistics, this publication includes total energy production, consumption, and trade; energy prices; overviews of petroleum, natural gas, coal, electricity, nuclear energy, renewable energy, and international petroleum.

Alternative fuels have the potential to provide significant economic and environmental benefits to airports and their communities. These fuels can lead to improvements in local air quality emissions and reductions in life-cycle greenhouse gases. In addition, alternative fuels offer the possibility to diversify away from imported conventional petroleum-derived fuels and enhance energy security. Furthermore, alternative fuel distribution programs offer airports additional business opportunities to generate revenue through the operation of such facilities or leasing of land to third-party operators. Airports are natural nodes for multi-modal demand and are ideally situated to become distribution centers for a variety of alternative fuels for aircraft and surface transportation. Producers and marketers of alternative fuels can take advantage of this concentrated demand to strengthen their business case as they can cater to a wide spectrum of potential clients, including airlines, airports, and third-party operators such as rental car facilities, courtesy shuttles, taxis, buses, freight trucks, and other fleets that may operate nearby. This is especially the case for facilities that produce alternative jet fuel because, in addition to jet fuel, they also produce co-products such as green diesel, which can be used by some passenger and most cargo vehicles.
