Electric power system harmonic is one of the most important parameters. With the development of electric power and electron technology, a number of the nonlinear loads and all kinds of commutating equipments are widely applied in every walk of life, what they bring a mass of harmonic current make the content of harmonic increase in the power system and quality of power drop.

电力系统谐波是电能质量的重要参数之一，随着电力电子技术的发展，大量的非线性负载和各种整流设备被广泛的应用于各行各业，使电网谐波含量大大增加，电能质量下降。

It counteracted the establishing of electric market.

伴随着我国电力体制改革方案的出台，对国家电力公司分拆重组后，形成了五大发电集团与两大电网公司，这使电力市场引入竞争、打破垄断已成为必然趋势。

Roar of the machine shop, to buy rice from the farm after decorticating processing, rice husk was confined to the channel blowing specially designed boiler, after the fire by burning fat, energy directly into the national grid.

在机器轰鸣的车间，从农场收购的水稻经过剥壳处理后，稻壳被密闭通道吹送到专门设计的锅炉，通过燃烧后火力发的电能直接并入国家电网。

Without changing the equipments, the fault current can be limited by using delaminating and districting operation and some special operation.

在不更换设备的情况下，只能对电网通过分层分区运行和实施特殊运行方式来加以限制短路电流。

At the same time,the way to choose the scenario of on-line monitoring is also depicted.

后者是在变压器脱离电网的状态下用常规方法进行的。

We are pleased with the high level of local engineering support and services provided by IPS, and we look forward to working with them as we increase grid quality and reliability, improve competitiveness in Taiwan's deregulating utility market and reach our CO2 emission targets.

我们很高兴英维斯过程系统所提供的高水平本地施工支持及服务，我们也期待着与他们共同合作，因为我们需要加强电网的质量和可靠性，在台湾开放管制了的电力市场提高竞争力，以及实现我们的二氧化碳排放目标。

World wide web is so limited in China and most industry sites are built in rural area that it is difficult to make use of network to reach synchronization, thus, the synchronization board in this thesis is to set up a emendation system in every computer and realize synchronization through emending their system time.

由于我国互联网普及范围还很有限，并且许多工业站点、电网站点等建在比较偏僻的地方，难以实现网络授时。

The report is epitomized from the concluding speech on the 26th China Electric Power System Control and Operation Conference.

摘 要：是第26届中国电网调度运行会议闭幕式上的总结报告节选。

It buys turbines, erects them and sells the electricity they generate to China's power distributors at prices fixed by the state.

从事的业务就是购买风机并组装树立起来，然后再按照国家规定的固定价格将生产出来的电力销售给中国的电网企业。

After the research it is held that when internal fault takes place in the transmission line where the series compensation device is located, the corresponding protective measures, e.g., the forced triggering the by-pass gap, etc., is the effective approach to avoid the appearance of excessing level of transient recovery voltageand oversize coupling current.

文章结合我国南方电网河池固定串补及平果可控串补工程，对超高压输电线路装设串联电容补偿装置后的系统状况进行了比较深入的研究，指出一些系统问题，如过电压水平升高、潜供电流增大和可能发生的次同步谐振均源于串联电容补偿装置的固有特性，通过研究认为当串补所在输电线路发生内部故障时，采取强制触发旁路间隙等保护措施，是避免出现系统恢复电压水平超标和潜供电流增大等问题的有效途径。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
