中压用户配电系统可靠性评估

Reliability Evaluation on Middle Voltage Distribution Network

在对中压用户配电系统故障扩散法评估算法研究的基础上,可以知道该算法利用故障扩散法确定断路器动作影响的范围,并确定故障范围与切换开关的有无,从而确定了节点的故障类型。根据节点的类型,可以计算出供电系统的可靠性指标,并提出了提高中压配电系统供电可靠性的技术与管理措施。

A reliability evaluation algorithm for middle voltage radial distribution networks was presented. The algorithm applied fault-spreadingmethod to determining the area of breaker influencing, and affected zone and connecting switch, then the type of nodes is determined. The reliability index of nodes can be carry out by the type of nodes. As the same time, the management measures and skills on improving the reliability of middle voltage distribution networks was mentioned.
