摘要 靠近负荷中心的分布式发电系统对配电网有着多方面影响。文中研究了分布式电源接入放射状链式配电网络前后负荷节点电压的变化。针对开式配电网,运用潮流程序进行多分布式电源接入后电压分布的计算。提出专门评价节点电压前后变化的指标。结合分布式电源出力变化、接入位置变化以及与线路电压调节配合的试验,全面总结了分布式电源在配电网中接入位置、出力限制等方面的运行规律。研究结果表明只有合理正确运用分布式电源,才能真正发挥电压支撑作用。 Distributed generation (DG) near to load center has several kinds of serious potential impacts on distribution system. This paper conducts study on voltage changes when some certain capacity's DGs are penetrated into radial feeders. Power flow method is applied to obtain the voltage profile for the open loop feeders. A special voltage change index is proposed to evaluate the effects. The general operation guidelines are revealed primarily after several simulations where the DGs' outputs change, the DGs' locations change and DGs co-ordinate with line voltage regulator. The results show that DGs could provide valuable and active voltag;e support only if they are applied appropriately.
