IEC TR 63292:2020继续从可用性技术规范（IEC TS 63019）开始的工作。可用性与PVP的操作能力、健康和状况以及产生能量密切相关，并且是实时或历史测量。系统或组件的可用性受到合同和非合同可靠性规范、维护指标和相应的维护和维修策略以及现场环境和电网条件等外部因素的影响。本文件的目的是对可靠性问题进行初步检查，以便在制定有关该主题的IEC技术规范的任务中进一步解决。 虽然本文档确定了可靠性工具、主题和程序，但有商业产品可用于执行分析，并且本文档中没有对这些工具进行评估或提供一种工具优于另一种工具的建议。

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.
