摘要
浙江海宁35.6MW分布式光伏发电项目利用厂房屋顶为场所布置光伏电池板,就近接入用户20kV高配供电系统。20kV并网系统设计包含了一次系统设计、二次系统设计和保护整定计算,并以分布式光伏发系统和电网参数为基础,计算分析了分布式光伏对电网电压波动、偏差和短路电流的影响,可为类似分布式光伏发电接入配电网提供参考。
Zhejiang Haining 35.6 MW dislributed photovoltaic power generation project uses the roof of the plant to arrange tile photovohaic panels ,and accesses the nearest 20 kV high power supply system. The design of 20 kV grid connected system consists of primary system design,secondary system design and protection setting calculation. Based on the distributed photowtaie system and grid parameters,the effects of distdbuted photovoltaic on voltage fluctuation,deviation and short eireni! current were ealeulated and analyzed. It can provide referenees for sinfilar distributed photovohaie power generation.
