Abstract
我国城市化的迅速发展迫使电力负荷密度的快速增长,传统的10KV已不能满足电力发展的需要,35KV的中压配电网的电压等级在使用中又存在着许多的局限性,所以20KV就成为当前比较合理的选择。本文以天津NQ新兴产业区为例,对中压配电网采用20KV电压等级进行研究分析。
China’s rapid development of urbanization promotes the swift growth of power load density, in other words, the traditional 10KV can no longer meet the needs of power development, and moreover, the voltage class of 35KV medium-voltage distribution network has a lot of limitations in use, so that 20KV has become a more reasonable choice at present. In this paper, the author takes NQ emerging industry district in Tianjin as an example to study and analyze the use of 20KV voltage class for medium-voltage distribution network.
本文以电压等级序列合理配置的原理及电压等级为基础,分别对10KV、20KV及35KV不同电压等级的技术特点进行分析,并对NQ新兴产业区采用20KV电压等级的实际应用情况进行论证。
In this paper, on the basis of the principle of reasonable allocation of voltage class sequence and voltage class, the author analyzes the technical characteristics of different voltage classes including 10KV, 20KV and 35KV and further demonstrates the actual application of 20KV voltage class in NQ emerging industrial district.
文中利用小负荷密度法分别对220/35KV、220/20KV及220/110/10KV三种不同的电压等级进行电力平衡、容载对比。根据三者对比结果,从供电方案规划、电气分析及安全性校验等方面,对NQ新兴产业区采用20KV电压的可行性进行分析。
In this paper, the author compares the power balance and capacity loads of three different voltage classes including 220/35KV, 220/20KV and 220/110/10KV by using small load density method. According to the comparison results among them, the feasibility of 20KV voltage adopted by NQ emerging industrial district is analyzed in terms of power supply scheme and planning, electric analysis and safety verification, etc.
最后将可靠性、电压质量及经济分析等多方面对不同供电方案的分析结果,与不同负荷密度及电压等级序列选取的影响相结合,得到NQ新兴产业区中压配电电压等级及电压等级序列。
And finally, the author combines the analysis results for different power supply schemes from these aspects of reliability, voltage quality and economic analysis with the influences of different load densities and voltage class sequences chosen to obtain voltage class and voltage class sequence of medium-voltage power distribution in NQ emerging industrial district.
