Validation activities are an essential part of all product and system development processes. Validation of project results is also an important task in all research projects. The Horizon 2020 work programme 2018-2020 defines validation as one of the key elements of the Research and Innovation Action (RIA) projects. These projects may include basic and applied research, technology development and integration, testing and validation on a small-scale prototype in a laboratory or simulated environment. Projects may contain limited demonstration or pilot activities aiming to show technical feasibility in a near to operational environment. In general in industrial context validation activities form a process to support the development process and to evaluate the results against the stakeholder requirements. Validation means confirmation, through the provision of objective evidence, that the requirements for a specific intended use or application have been fulfilled. In MegaRoller research and innovation action a systematic validation process is developed to demonstrate that the models and technical solutions produced in the project meet the project objectives regarding PTO performance, power quality and reliability, and environmental and sosio-economic impact and cost reduction of the MegaRoller device. The methodology developed in MegaRoller project combines systematic analysis, simulation and test methods. The aim is to ensure that the multi-technological and innovative MegaRoller device and its PTO system meets all the specified project objectives and system design requirements. The methodology covers activities for evaluation of PTO’s functional performance, output power quality and reliability performance. It also covers life cycle costs and environmental and socio-economic aspects regarding the MegaRoller device and its operation and maintenance at its location. The evaluation criteria are derived and defined from the project objectives and adapted to the requirements issued by the EU for the demonstration of project results in Technology Readiness Level 5 (TRL5). At TRL5 level the technologies should be validated in relevant environment i.e. industrially relevant environment in the case of key enabling technologies This public report describes the methodology developed and applied in MegaRoller project in the four above mentioned sections of the overall system evaluation. The methods and plans for PTO performance and power quality evaluation focus on the functionality of the PTO, power performance measurements (pressure, temperature, position and voltage measurements along the power conversion chain) and the power quality measurements (voltage and frequency of the electricity fed into the grid). The methods and plans for the evaluation of reliability performance of the PTO system are based on Failure Mode, Effects and Criticality Analysis (FMECA) in a functional level. Reliability modelling and simulation approach utilizing reliability block diagrams (RBD) is used to evaluate the achievable reliability performance levels for different PTO design options and component parameters. Assessment of environmental and socio-economic aspects is based on Environmental Impact Assessment (EIA) and Socioeconomic Impact Assessment (SEIA) models of the MegaRoller device. Life cycle Assessment (LCA) method is used to assess the cumulative environmental impacts of the MegaRoller device over space and time throughout its overall life cycle. The assessment of life cycle costs (LCC) of the MegaRoller device aims at evaluating that the system design and the operating and maintenance concepts are able to achieve pursued cost reduction. The system cost breakdown structure is created and LCC of alternative designs are calculated using a LCC simulator tool. The validation and impact assessment results will be presented in separate confidential reports. |
