摘要
从供电能力、电压质量、功率损耗(包括线路损耗和变压器损耗)以及经济技术等方面较为全面的分析比较了20 kV和10 kV的配电情况。分析比较的结果表明,20 kV配电明显优于10 kV配电。文章对推广20 kV配电提了建议,并指出了对于已建设成熟的10 kV配电网,一般不宜再升压改造为20 kV。
The paper analyzed and compared the conditions of 20 kV and 10 kV distribution network from power supply ability, voltage quality, power loss including line and transformer losses as well as the aspects of economy and technology. The results show that the 20 kV distribution network is better than the 10 kV distribution network obviously. The paper presented the suggestion for popularizing the 20 kV distribution network, and pointed out that it is not suitable to retrofit for 10 kV distribution network that has built to come maturity.
