Design of seismic test platform for electrical equipment with large-scale renewable energy generation

The research on ultra-high voltage AC/DC transmission systems with large-scale renewable energy generation (REG) has become a hot topic of widespread concern in the industry, the anti-seismic level of UHV AC/DC electrical equipment has always been concerned by users and anufacturers. Through seismic test of the equipment, the basic data such as the natural frequency, acceleration of key parts and strain response of the equipment can be obtained, which is of great significance to discover the potential defects of the equipment and improve its seismic level. This paper analyzes the characteristics of typical seismic structures of electrical equipment and requirements of relevant test standards. According to the parameters and structural system characteristics of seismic sensitive equipment, and considering the manufacturing capacity of seismic table and standard requirements, a UHV AC/DC dual array seismic test platform is designed. In addition, this paper also gives a brief description of the requirements related to civil engineering and electromechanical design of the seismic laboratory, which can be used as a reference for those engaged in relevant test research and laboratory design.
