摘要
在研究配电系统安全性评估的基础上将风力发电接入系统加以讨论。根据实际应用情况,将风力发电机组作为一种随机电源来考虑,并且引入"孤岛形成概率"的概念,从系统发生故障的概率和故障后果两部分着手,研究分析含有风力发电的配电系统安全性评估指标,并通过实际算例分析验证了该套安全性评估指标的实用性。用该套指标来表征风力并网配电系统的安全性水平,对于不同地区的系统网络或者同一地区的不同规划方案,都具有重要的指导意义。
In this paper,the safety index of the distribution system with wind power is discussed based on the research of the power distribution system.According to practical situation,the wind power generation unit is considered as a random power,and introduced the concept of＂Island formation probability＂.Research and analysis of the safety evaluation index of the distribution systems containing wind power,from the two aspects of system failure probability and failure consequence.And through the actual example verifies that this set of safety evaluation index of practicality.The set of indicators to characterize the security level of grid connected wind the power system for different regions of the network or the different planning schemes of the same area,all has important guiding significance.
