摘要
介绍了无锡太湖新城110/10 kV和110/20 kV供电方案的规划,运用动态经济分析法计算了2个方案的年综合费用、年电力损耗费用和年投资费用,同时分析了该供电方案的供电可靠性、最大短路电流以及最大电压降落等技术指标。经过对比得出结论是该地区采用20 kV电压等级技术可行、经济优势明显。
Power supply schemes of 110/10 kV and 110/20 kV in Wuxi Taihu new town were introduced.The annual general cost,annual power loss cost and annual investment of these two schemes were computed by applying dynamic economic analysis method.Technical criteria of the schemes including power supply reliability,maximum short-circuit current and maximum voltage drop were also analyzed.It was concluded based on the comparison that the application of the 20 kV voltage grade in this area is technically feasible and also has obvious economic advantage.
