摘要
光伏并网发电系统对配电网的电压分布有着重要的影响,它的接入位置和接入容量大小与配电网的电压有很大关系。研究了放射状链式配电网络在并入一定容量的光伏发电后各节点电压幅值的变化情况,结合电压分布的特点,对光伏并网发电的可行接入位置以及注入容量进行了理论探讨。研究表明从稳态电压分布的角度来看,光伏并网发电接入馈线的位置和注入容量的大小有严格的要求。
The grid-connected photovohaic (PV)system has a significant impact on the voltage profile of distribution system, and its access position and injection capacity, to a large degree, depends on the voltage of the distribution system. The changes of the amplitude of each node voltage are studied when PV generation systems integrates into the radial distribution chain system. Combined with the characteristics of voltage distribution, the feasible access position and possible injection capacity of the grid-connected PV system is discussed. The research clarifies that, in sense of the steady-state voltage distribution, PV connected to the feeders has strict requirements for its access position and injection capacity.
