浅析城市配电网建设中存在的问题

通过对部分城市配电网建设中出现的一些问题,开展研究分析并对城市配电网的建设与以往的配电网进行比较,得出了研究数据。其意义就是为了加强城市配电网的功能和实效,提高为国家输送可靠电源的能力,为国民经济又好又快发展提供坚强保证。

配电自动化技术在城市配电网建设中的应用

电力作为国民经济发展重要的基础能源,电力供电质量和供电可靠性直接关系到每一个人的生活。我国城市配电网在建设过程中,受到经济水平和技术限制等方面的影响,城市配电网建设不合理,无法满足城市居民实际电力需求。将配电自动化技术运用在城市配电网建设中,可以实现配电网运行自动化设备检修、数据采集和数据监测、故障检修、用户管理等功能。

地埋变在城市配电网中的运用

箱式变电站在城市配电网中已经广泛应用,但是在城市中心区建设地上箱式变电站与当前城市建设的美化、亮化要求以及与周边环境存在诸多不和谐因素,文中着重介绍了新一代地埋式箱变的结构特点及其在城市配电网中的应用优点。

Analysis on Regional Power Grid Load Characteristics and Rational Allocation of Capacity Load Ratio

The reasonability of the adopted capacity load ratio numerical value in urban power grid planning determines the economy of planning level yearly power grid.Too large capacity load ratio will result in the increasing investment in the early period of power grid construction, however, too small capacity load ratio will make the power grid have poor adaptability, affecting the power supply. Reasonably determining the adopted regional power grid capacity load ratio quantitative numerical value in planning has a strong guiding significance for constructing reliable and economic power grid and preventing power grid from excessive advance or lagging behind the load development. This paper, through the statistics and analysis of a certain regional power grid 2010-2012 three years＇ power grid daily load characteristics and the investment benefit evaluation of three years＇ 220KV power grid individual project, makes a preliminary analysis and puts forwards the specific advice on the reasonable values of power ~rid 35-220KV power transformation capacity load ratio.
