光伏发电系统（PVPSs）-稳健可靠性路线图

[中文适用范围]： 光伏系统（PVPS）组件和系统的可靠性工程旨在定义光伏系统产生特定价值（如能量或收入）的概率，该概率需基于实际电厂在广泛不同实地条件下的实测数据，并以一定的统计置信水平进行评估。准确的平准化度电成本（LCOE）结果源于基于实测数据确定并实施一组可量化指标。在此过程中，P值（如P50、P90、P95）用于建立置信度，以确保项目满足规范。P90或P95值对于表征电厂的财务和技术风险可用性至关重要。该范围还涉及失效模式、根本原因分析、LCOE计算中的成本考量，以及从概念设计到全生命周期的可靠性分析对于识别、维护、纠正和理解成本的重要性。 [外文原描述]： IEC TR 63292:2020 continues the effort started with the availability technical specification (IEC TS 63019). Availability is closely related to PVPS operational capability, health and condition and to produce energy and is a real-time or historical measure. The availability of a system or component is impacted by contractual and non-contractual reliability specifications, maintenance metrics and a corresponding maintenance and repair strategy, and also external factors such as site environmental and grid conditions. The intention of this document is to be a precursor examination of the reliability issues for further address in a task to produce an IEC Technical Specification on this topic. While this document identifies reliability tools, topics and procedures, there are commercial products available to perform analyses and there is no assessment of those tools or to provide recommendations for one tool over another in this document.
