摘要: 随着能源互联网及综合能源系统建设的不断深入,不同能源系统之间的关联耦合特性进一步加深。现阶段综合能源系统研究中对故障在综合能源系统内的传播影响分析不够深入,且未考虑不同能源子系统的故障连锁。针对此问题提出综合能源系统级联失效及故障连锁反应分析方法。首先,以综合能源系统为研究对象,从宏观层面分析了综合能源系统的故障连锁失效机理,同时分别对天然气系统、电力系统及热力系统的故障影响进行了细致分析;其次,分别从拓扑完整性和失效级联影响度2个维度提出了综合能源系统连锁故障影响评价指标,并梳理了连锁故障影响的分析流程;最后,通过构建综合能源系统的测试算例,验证所提方法的有效性与实用性。

Abstract: With the deepening of the construction of energy internet and integrated energy system, the coupling characteristics between different energy systems have been further deepened. In view of the fact that the influence of fault propagation in the integrated energy system have not been deeply analyzed at this stage, and the problem of fault linkage of different energy subsystems have not been taken into account, this paper puts forward the analysis method for cascade failure and fault chain reaction of integrated energy system. Firstly, taking integrated energy system as the research object,  the fault chain failure mechanism of integrated energy system is analyzed from the macro level, and the fault effects of natural gas system, power system and heat system are analyzed in detail. Secondly, the evaluation index of chain fault reaction of integrated energy system is put forward from two dimensions of topological integrity and failure cascade loudness, and the analysis flow of chain fault influence is combed. Finally, the effectiveness and practicability of the proposed method are verified by a test example of an integrated energy system.

Key words: natural gas system, power system, heat system, cascade fault, impact analysis
