Abstract

According to the DC and AC distribution system with the classified load, the maximum transmission capacity is calculated. The price of the main devices in the distribution system including DC breaker, DC converter, etc. is analyzed. Taking the proposed 10kV AC, ±7.5kV DC and ±15kV DC distribution system for example, the economic comparison for AC and DC distribution system is analyzed considering their construction costs and transmission loss rate. The result shows that both the maximum transmission capacity and construction costs of DC distribution network is higher than those of AC distribution system, and the higher the voltage level, the larger the maximum transmission capacity and the construction costs will be. And the transmission loss rate of DC distribution system is significantly lower than AC, and the higher the medium voltage DC load ratio is, the lower the rate of transmission loss will be.
