10kV,20kV配电方案分析与比选

Analysis and Selection of 10kV,20kV Distribution Power Grid Economics

以南京丰盛科技园为例,比较10 kV,20 kV城市中压配电网的经济性,得出20 kV城市配电网比10 kV中压配电网在经济上的优越性,并分析了20 kV电压等级电价对供电用户的影响。建议我国城市中压配电网推广20 kV电压等级,以逐步取代10 kV电压等级。

This paper takes the distribution power grid of Nanjing Rich Science and Technology Park for example and compares eco- nomics of 10 kV, 20 kV medium voltage distribution power grid. The result shows that 20 kV distribution power grid is more economic than 10 kV medium voltage distribution power grid and 10 kV electricity price of users is higher than 20 kV, so our country urban medi- um voltage distribution network is recommendated to gradually use the 20 kV voltage level, instead of the 10 kV voltage level.
