IEC TS 63265:2022概述了可用于确保整个PVPS项目阶段可靠性的方法。它源于对持久且具有成本效益的能源绩效、能源生产、安全生产和收入以及安全功能的管理动机。本文档中可靠性实践的应用旨在实用并降低不可靠性的成本。本文件进一步确定和定义了一套规范性的最低流程和工具，以满足本文件的要求。 本文件的主要目标是向用户提供可靠性工具和评估方法（历史、预测和分析），以满足利益相关者对可靠光伏发电系统（PVPS）运行的需求。本文档提供了确保可靠性需求能够被理解和满足的基本流程。IEC TS 63019解决了可用性问题，可用性是一个结合了可靠性和可维护性的更高级别的指标，它作为一个关键的规范标准补充了本文档。它应与本文档结合使用。

IEC TS 63265:2022 outlines methods that can be utilized to ensure reliability throughout the PVPS project phases. It is derived from a management motivation for long lasting and cost-effective energy performance, energy production, secure production and revenue, and safe function. The application of reliability practices in this document is designed to be practical and reduce the costs of unreliability. This document further identifies and defines a normative minimum set of processes and tools to meet the requirements of this document.
Key objectives of this document are to inform users of reliability tools and assessment methods (historic, predictive, and analytical) that can satisfy the stakeholders needs for dependable PV Power System (PVPS) operation. This document provides a fundamental process for ensuring reliability needs can be understood and met. IEC TS 63019 addresses availability which is a higher-level metric that combines reliability and maintainability, and it complements this document as a key normative standard. It should be used in combination with this document.
