Abstract:

针对网络结构无法明确给出的规划目标年的城市电网供电可靠性指标预测,传统可靠性评估预测方法难以实现这一目标,本文提出了两种基于统计方法的城市电网供电可靠性预测新方法,一种是基于历史数据的可靠性趋势预测方法,另一种是考虑相关影响因素的供电可靠性预测方法。文中给出了新方法的具体思路和应用步骤,通过将其应用于南方电网及各省典型城市"十一五"未来几年的供电可靠性预测工作中,得到了供电可靠性预测指标,在此基础上,根据相关原则并结合电网的具体情况综合考虑确定合理的供电可靠性目标值。同时提出了提高供电可靠性水平的技术措施和管理措施。结果表明所提方法是十分有效的,可用于实际城市配电网供电可靠性规划预测。本文给出了南方电网城网供电可靠性规划工作的原则、目标、思路及步骤,研究成果对科研和生产部门有重要的指导意义和参考价值。
