摘要
新一代智能变电站已成为变电站未来的发展方向。目前针对新一代智能变电站一次系统或继电保护系统可靠性的评估仅限于系统本身,并没有综合考虑这两个系统对新一代智能变电站可靠性的影响,从而导致评估得到的可靠性指标偏高。首先根据新一代智能变电站继电保护的结构,建立了基于最小路集算法的可靠性模型。然后提出一种综合考虑继电保护系统及一次设备的等效可靠性指标,并利用上述模型及等效指标计算新一代智能变电站的可靠性。最后通过算例验证了所提方法的有效性。
A new generation of smart substation has become the future of substation. At present, the reliability assessment method of a new generation of smart substation is based on substation system or relay protection system separately, without considering the comprehensive influence of this two systems, resulting that high reliability index are obtained. Based on minimum path algorithm, firstly, this paper establishes the reliability model of a new generation of smart substation relay protection system. Then, the equivalent index considering the comprehensive influence of the primary system and relay protection system is put forward. And a new generation of smart substation reliability is evaluated by the above model and the equivalent index. Finally, an example is given to verify the effectiveness of the proposed method.
