摘要:
研究了输电网在雷击灾害下的可靠性评估问题。根据雷击灾害等级,利用线路分段模拟方法建立了输电线路可靠性模型;根据概率论与数理统计原理及高压输变电设备的绝缘配合使用导则建立变电站设备的可靠性模型;提出了基于复杂网络理论的输电网各元件可靠性指标权重设置,最终建立了输电网在雷击灾害下的可靠性综合评估模型。以某地区局部高压输电网为例,验证了该综合评估模型的科学实用性,对权重系数与雷击灾害下输电网可靠性关系进行了灵敏度分析,并根据算例结果,对电力系统防雷设计提出了建议。
Abstract:
A comprehensive reliability assessment model for transmission grid under lightning is proposed. Transmission line is segmented according to the lightning grades. Reliability model of substation is established according to the principle of statistics and the guidance of high voltage insulation coordination. The complex network theory is utilized for the weights setting of reliability indexes. A real high voltage transmission grid is taken for example to demonstrate the feasibility of the proposed reliability evaluation model. The sensitivity of the relationship between the weight coefficients and the system reliability under lightning is also analyzed. In addition, some suggestions for lightning protection of power systems are offered.
