The electrical barrier, installed in 2002 to repel fish with non-lethal jolts, had been thought to be the only thing standing between the carp and Lake Michigan.

于2002年建成的五大湖区电网用于驱赶鱼类，而其所带电压不足以将它们致死。这些电网曾被认为是阻止亚洲鲤鱼进入密歇根湖的最后屏障。

Britain and some residential and glass roof sun room at the top of the laying of a solar collection to solve day-to-day household consumption of electricity, enough electricity to power grids could be electricity, solar energy is insufficient input from the power grid.

英国和一些住宅和玻璃屋顶阳光室顶部铺设了太阳能收集来解决日常的家庭消费的电力，足够的电力电网可发电，太阳能是不够投入电网。如何建造节能住宅-设备和生产技术要求，以改善住宅物业革命

The results indicate the validity and effectiveness of this method in improving voltage quality and minimizing line loss.

另一方面，无功优化在焦作电网的成功应用将大大提高焦作电网的运行电压质量和降低运行网损，势必带来显著的经济效益和社会效益。

To accurately get the loss of Power System and find a Reasonable approach to reduce loss, we develop a Line Loss Management of Power System.

为了准确掌握电网的损耗情况以及提出合理的降损措施，开发了用于电力企业的电网线损管理系统。

The biggest advantages of this fashion is that when single-phasegrouded, three-phase line voltage symmetry was not damaged, so electricity userswill not be affected.

这种接地方式最大的优点是：当发生单相接地时，三相线电压的对称性没有被破坏，所以用户有电不受影响，可维持一定长的时间，这对电网结构比较薄弱，自动化水平比较低的配电网是至关重要的。

With the increase of the electric network scale, the power system analysis personnel attach importance to the load modeling of Wide Area Power System, the single load modeling method can not meet the demand of WAPS modeling.

随着当前电网规模的日益增大，广域电力系统的负荷建模引起了电力系统分析人员的重视，单一的负荷建模方法已无法适应当前广域电网建模的需求。

In this thesis, the significance and research progress of WAPS based on wide-area information of power grid are introduced at first, then basic discipline of WAPS is expatiated.

广域保护系统利用电网广域信息进行保护策略的制定，因而能够实现电网中不同地点保护之间动作的协调配合。

This system geares to security of power grids, and it also has an important practical sens to improve automation level of network remote monitor system

本系统以电网安全运行为目标，对提高电网远程监测系统的自动化水平也具有重要的现实意义。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
