摘要
为了提高规划阶段配电系统的评估水平,解决配电系统中存在的电能质量问题,提出了一种混合式电路分析算法。该算法不仅能评估电网中元件可用性,还能在配电系统规划阶段结合瞬时中断来评估电能质量影响。设计了一个包含16个节点的配电系统,并通过仿真验证了电网几何模型对电能质量指标影响的结果,最终结果表明所提算法能够有效减少电网中电压骤升次数。所提算法对规划阶段配电系统的评估起到了一定借鉴作用。
In order to improve the evaluation level of distribution system in the planning stage and solve the power quality problems existing in the distribution system,a hybrid circuit analysis algorithm is proposed to evaluate the availability of components in the power grid,and the impact of power quality is evaluated by combining instantaneous interruption in the planning stage of distribution system.In the simulation stage,a distribution system with 16 nodes is designed.The simulation results show that the proposed algorithm can effectively reduce the number of voltage surges in the power grid.The proposed algorithm can be used as a reference for the evaluation of distribution system in the planning stage.
