赛拉图轿车不能起动故障1例

<正>故障现象一辆赛拉图轿车发动机熄火后,再不能起动运转。车主请求笔者前去救援。笔者赶到现场后查看:故障车是赛拉图欧风1.6GL MT,生产厂家是东风悦达起亚,于2011年7月出厂,已行驶了14000km,目视车况良好。于是笔者试车,将点火开关置于ON档时,仪表板各指示灯闪亮,但充电指示灯不亮(正常情况,该步骤充电指示灯应该亮);将点火开关置于ST档时,起动机不能带动     

抛石地基中不透水连海构筑物设计技术

为维护海域海岛自然生态环境,常需要在围堤上建设连海构筑物.连海构筑物的建设往往受到地质、周边复杂环境等条件的影响和限制,导致结构选型困难、防渗止水不易等技术难题.以舟山绿色石化基地用海用岛整治工程为例,针对抛石地基和用海环境受限的复杂条件,开展构筑物结构选型、止水防渗、结构计算、施工工艺等关键技术研究,提出冲孔塑性混凝...     

Distributed Power Control Considering Different Behavioural Responses of Electric Vehicle Drivers in Photovoltaic Charging Station

A distributed energy management in a photovoltaic charging station(PV-CS) is proposed on the basis of different behavioural responses of electric vehicle(EV) drivers. On the basis of the provider or the consumer of the power, charging station and EVs have been modeled as independent players with different preferences. Because of the selfish behaviour of the individuals and their hierarchies, the power distribution problem is modeled as a noncooperative Stackelberg game. Moreover, Karush-Kuhn-Tucker(KKT) conditions and the most socially stable equilibrium are adopted to solve the problem in hand. The consensus network, a learning-based algorithm, is utilized to let the EVs communicate and update their own charging power in a distributed fashion. Simulation analysis is supported to show the static and dynamic responses as well as the effectiveness and workability of the proposed charging power management. For the sake of showing the responses of EV drivers, different behavioural responses of EVs' drivers to the discount on the charging price offered by the station are introduced. The simulation results show the effectiveness of the proposed energy management.
