电能质量 讲座 第二讲 分布式电源接入与电网电压偏差

Distributed Power Supply Access and Grid Voltage Deviation

针对分布式电源接入配电网引起的电压偏差问题进行研究。首先介绍电压偏差的含义和形成机理,重点阐述分布式电源接入对电网电压偏差的影响,分析配电网与输电网电压偏差问题的差别,解释分布式电源接入配电网的几种不同情况下电压偏差的分布情况。最后,探讨利用分布式电源抑制电压偏差的可能性和适用场合。

The problem of voltage deviation caused bydistributed power supply access distribution network was studied. Firstly, the meaning and formation mechanism of voltage deviation are introduced. Next, the influence of distributed power supply on voltage deviation and the difference of voltage deviation between distribution network and transmission network are analyzed. And then,the distribution of voltage deviation in several different situations of distributed power supply access to the distribution network is explained. Finally,the possibility and application of suppressing voltage deviation using distributed power supply are discussed.
