摘　　要：目前,智能变电站过程层网络化进程在不断推进,但智能站过程层网络传输可靠性尚无量化评估方法。为了提高智能站组网的规范性和可靠性,迫切需要针对智能站过程层网络提出一套完善的可靠性评价方法。可靠性评价方法包含多个关键评判指标,基于各评判指标对网络可靠性影响程度赋予不同权重值,实现对各种组网架构下的网络数据传输安全可靠性进行客观评价,考虑各电压等级技术经济因素,实现网络方案的最优选择。At present, the process layer networking process of smart substation is constantly advancing, but there is no quantitative method to evaluate the transmission reliability of the process layer network of smart station. In order to improve the standardization and reliability of smart station networking, it is urgent to put forward a complete set of reliability evaluation methods for the process layer network. The reliability evaluation method includes several key evaluation indicators. Based on each evaluation indicator, different weight values are assigned to the influence degree of network reliability to objectively evaluate the security and reliability of network data transmission under various networking architectures. It is necessary to consider the technical and economic factors of each voltage level to realize the optimal selection of network scheme.
