摘要
在微电网技术发展的基础上,本文提出一种建筑直流配电系统,由AC/DC、直流母线、分布式电源、直流负荷、蓄能器、开关及保护装置等部分组成。论述了直流母线电压的稳压原理,蓄能器在直流母线电压稳定过程中起关键作用,AC/DC做为直流配电系统的后备电源及向电网馈电的逆变器。着重讨论了建筑光伏BIPV、电梯用电与再生发电及四象限运行、AC/DC及蓄能器的特性等。
Based on the progress of micro-grid technology, the paper presents a building DC distribution system. The system consists of AC/DC converter, DC bus, distributed power, DC load, accumulators, switches, protective devices, etc. This paper discusses stabilized voltage principle of the DC bus voltage, and how accumulators play a key role in the stabilization pi~）cess of the DC bus voltage. The paper also discusses how AC/DC converters are used as both a backup power supply of the DC distribution system and the inverter for feeding grid, and focuses on discussing Building Integrated Photovoltaic（BIPV）,elevator power consumption,elevator renewable power generation,four- quadrant operation of the elevator,AC/DC converter and the characteristics of the accumulator, etc.
