| Popis: | Within the complexity of the design and execution of a solar power plant project, one of the main challenges falls on rainwater management, since there is the need to collect, conduct and store it for its use in the water-vapour cycle process. Therefore, the primary piping for rainwater transportation from the solar power plant is regarded as an essential installation for the operation of the plant. Within this framework, the appearance of pathologies in its conduction just a few months after the plant start-up is considered to be a critical problem, as it can endanger the electrical production of the facility. This problem has taken place at the solar power plant of “La Asturiana”, in Southern of Spain, with a solar field of 2 Mm2 in size and a gross generation capacity of 50 MW. The need to understand the reason for the pathologies, in order to prevent their reappearance, justifies a detailed analysis of the adopted design, as well as its execution. The research is completed with novel techniques for in-situ tests, which enable us to obtain rigorous data to be used in computer models with the aim of reproducing, in a controlled way, the execution conditions in order to establish the causes of the failure. |
