单相配电系统应用于城市居民小区的探讨

Study of Single-phase Power Distribution Systems in Urban Residential Areas

针对传统三相四线制低压配电方式存在的线路损耗大等问题,提出单相配电系统的接入方式,以某城市居民小区为例,对2种配电方式的功率损耗和设备投资进行比较,认为单相配电系统可有效降低电网损耗,提高居民供电质量。

The traditional three-phase four-wire system in low voltage can cause large line loss .T his paper proposes the access mode of single-phase distribution system ,taking a real urban res-idential area case as an example ,this paper compares the power loss and equipment investment of power distribution mode of single-phase and three-phase respectively ,considers that the sin-gle-phase power distribution mode can effectively reduce the dis-tribution loss and enhance power supply quality .
