As the junction of transimmting and distributing power, the power transformor is at the core of power network, so its reliability works on power energic quality for amoutful consumers, and the safety of power system even.

电力变压器是传输、分配电能的枢纽，是电力网的核心元件，其可靠运行不仅关系到广大用户的电能质量，也关系到整个系统的安全程度。

The development tendency of power quality supervision technology towards netlike, informization and standardization is analyzed from supervision method, content and system functions.

在简述电能质量特点、监测目的和要求的基础上，从监测方式、内容、系统功能等各方面介绍了电能质量监测技术正在向网络化、信息化、标准化的方向发展。

The second part of the thesis classifies the problems of power quality. This part introduces all power quality problems.

文章第二部分对电能质量问题进行了分类，分别对各种电能质量问题进行了介绍。

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。

When wind energy and solar energy are sufficient, wind turbine and photovoltaic arrays can satisfy load demand and at the same time they can feed electrolyzer; when wind energy and solar energy cannot satisfy load demand, the FC system will provide supernumerary electric energy, at the same time the deficient part of load power excessing the maximum power supply ability of FC system can be fed by UC bank in a short-term.

当风能与太阳能充足时，风机与光伏阵列可满足负荷的需要，同时还可向电解池供电；如果不能满足负荷的需要则由燃料电池提供额外的电能，同时由超级电容在短时期内向负荷提供燃料电池最大功率以外的那部分电能。

Time-scheduled tariff system, that changes user s behavior in energy consuming and rationalizes the electrical energy utilization, is an effective and valuable measure to solve this problem.

但是传统的机电式电能表无法执行分时计量和分时计费的功能，因此基于单片机技术设计的新型数字电表是实现新型电能管理方式的前提。

Time-scheduled tariff system, that changes user's behavior in energy consuming and rationalizes the electrical energy utilisation, is an effective and valuable measure to solve this problem.

为了解决这一矛盾，电能计量的分时计费方式可以通过调节人们的用电行为，对提高电能利用的合理性和缓解电力供需矛盾具有重要价值。

为了解决这一矛盾，电能计量的分时计费方式可以通过调节人们的用电行为，对提高电能利用的合理性和缓解电力供需矛盾具有重要价值。

In various power quality problems voltage sags are the worst dynamic power quality problems.

在各种电能质量问题中，电压跌落是危害最严重的动态电能质量问题。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
