4 Frequently Asked Questions about “Seismic resistance level classification of communication base station inverters - RRR Renewable Projects (SA)”
What standards are used for seismic design of substations?
The two main interna tional groups of standards used for this work are IEEE 693 and IEC 61463. IEEE 693-2005, “Rec-ommended Practice for Seismic Design of Substations” is a newly revised document covering the procedures for qualification of electrical substation equip-ment for different seismic performance levels.
What are the three levels of seismic performance in communication systems?
The current research focuses on three levels: individual equipment, base station systems, and communication networks. At the level of individual equipment, the seismic performance of various critical equipment in communication systems has been studied [3, 4].
What are seismic functional fragility curves for communication base stations?
Seismic functional fragility curves for typical communication base stations are provided. The reliability and resilience of communication base stations are critical to the post-earthquake performance of the communication system, and consequently influence the communication, rescue, and emergence management after an earthquake.
How to improve a base station's seismic resistance?
For example, in areas with high PGA values, reinforcement measures such as increasing the thickness of reinforced concrete walls and installing supports or dampers can be implemented to enhance the base station's seismic resistance and reduce its seismic risk. 4.3. Functional failure causes of base station
