摘要:
220 kV变电站建筑在电网系统中地位非常重要,其承载能力安全性,尤其是其抗震能力,对电网系统稳定有决定性影响。为评估变电站结构抗震承载能力,明确其倒塌机理,从而为新建变电站结构抗震设计提供技术支撑。以国家电网江苏公司220 kV标准变电站结构为例,选取3条地震波,采用弹塑性时程法,分析结构在不同地震波不同输入方式下的响应。研究结果发现:三向地震波输入下变电站结构地震响应很大;结构的损伤、失效主要发生于结构薄弱部位;现有220 kV变电站结构的抗震承载力不高,鉴于其重要程度,其安全度应增强。
Abstract:
The constructions of 220 kV substation play an important role in the power grid system, its bearing capacity security, especially its seismic capacity, has a decisive influence on the stability of the power grid system. In order to evaluate the seismic bearing capacity of the substation structure and clarify its collapse mechanism, technical support for the seismic design of the new substation structure was provided. Taking the 220 kV standard substation structure of Jiangsu Power Grid Corporation of China as an example, this paper selected 3 seismic waves and adopted elastic-plastic time-history analysis method to analyze the response of the structure under different input modes of different seismic waves. The results showed that the seismic response of the substation structure was very large under three directional seismic waves. Structural damage or failure occurred mainly in the weak parts of the structure. The seismic capacity of existing 220 kV substation structure is not enough, and its safety should be enhanced in view of its importance.
