Abstract

Life cycle assessment (LCA) is conducive to the change in the wind power industry management model and is beneficial to the green design of products. Nowadays, none of the LCA systems are for wind turbines and the concept of Internet of Things (IoT) in LCA is quite a new idea. In this paper, a four-layer LCA platform of wind turbines based on IoT architecture is designed and discussed. In the data transmission layer, intelligent sensing of wind turbines can be achieved and their status and location can be monitored. In the data transmission layer, the LCA platform can be effectively integrated with enterprise information systems through the object name service (ONS) and directory service (DS). In the platform layer, a model based on IMPACT 2002+ is developed, and four management modules are designed. In the application layer, different from other systems, energy payback time (EPBT) is selected as an important evaluation index for wind turbines. Compared with the existing LCA systems, the proposed system is specifically for wind turbines and can collect data in real-time, leading to improved accuracy and response time.

Highlights

Wind energy is a type of important clean and renewable energy with abundant reserves
The energy consumption is measured by smart meters, and other data can be obtained through enterprise information systems (EIS)
To compare the life cycle assessment (LCA) workload between the proposed system and the existing software, we suppose the total workload of data preprocessing, goal definition and scoping, inventory analysis, and impact assessment of the existing software are all 100%, and the weights of them on the LCA workload are 30, 20, 40, and 10%, respectively

Summary

Introduction

Wind energy is a type of important clean and renewable energy with abundant reserves. As a green and environmental protection power generation technology, wind turbines can effectively reduce environmental pollution. Review of World Energy June 2019”, the annual growth rate of global wind farms in 2018 is 12.6%, and the power generation capacity is 1170.0 TWH. Life cyclethe assessment (LCA)environmental has made remarkableimpacts progress, since first life-cycleoriented methods were proposed in the Currently, is defined as a tool that life cycle, i.e., from raw material acquisition, via production and use s assesses the potential environmental impacts and resource consumption in a product’s agement general methodological framework and standards life cycle, i.e., [9]. The general framework and standards of LCA are four s by ISO 14040 and ISOmethodological 14044 [10,11] It includes the following defined by ISO 14040 and ISO 14044 [10,11].
