摘要
针对杭州地铁1号线三期工程中,铁南阳主变电所无法按时投入使用的情况,提出了3种临时支援供电方案,并从系统运行方式及可靠性、电缆压降和经济性3个角度对3种临时支援供电方案进行了计算和分析。根据计算分析结果,推荐了最优的临时支援供电方案,可为地铁行业中压环网支援供电方案提供借鉴思路。
In view of the situation that Tienanyang main substation of Hangzhou Metro Line 1 phase Ⅲ project can′t start operation on time as planned,three temporary support power supply schemes are proposed.The schemes are calculated and analyzed from three perspectives of system operation mode and reliability,cable voltage drop and economy.According to the calculation analysis results,an optimal temporary support power supply scheme is recommended,it can provide a referrable idea for support power supply schemes of metro industry medium-voltage ring network.
