本文件提供了光伏系统运行和维护的推荐最佳实践。本指南可能不包括所有操作和维护例行程序或场景，但为光伏系统的安全实践、管理、操作和预防性维护提供了一般指导。电缆设施中的太阳能光伏发电系统越来越普遍。有几个因素影响这些光伏系统的部署，包括电力成本高、电网可靠性降低、国家、州和公用事业公司的激励措施、碳减排和可持续性目标。 太阳能光伏发电在白天运行，用于基本、中等或峰值负荷发电，取代通常由当地电力公司提供的千瓦/兆瓦。光伏发电系统通常用于减少燃烧化石燃料产生的电力消耗，并增加可再生能源消耗的电力。大多数光伏系统可以通过增加储能来减少对电网的依赖，并在高消耗期为电网提供缓解。 当电网因高消耗而承受最大压力时，也是太阳能系统以峰值输出运行的时期。光伏系统的关键组件包括:•屋顶或地面安装的直流（DC）发电光伏板•直流（DC）至交流（AC）逆变器•配电系统•千瓦时（kWh）和电流（安培）计量和监测•配电系统断开和断路器屋顶安装的光伏系统是部署最多的系统在有线电视设施。 地面安装系统利用宝贵的地面空间，在大多数位置，设施地面空间有限。利用回收的地面空间，例如退役的碟形卫星空间，是部署地面安装系统的一种选择。光伏系统需要定期定期维护，以保持可靠性和运行效率。运维计划中最重要的领域之一是安全。只有合格且经过培训的人员或承包商才允许维修或维护光伏系统。 太阳能电力系统中最危险的部分是光伏系统产生的电力。在光伏系统周围工作时，需要配备电弧闪光保护、上锁/挂牌程序和屋顶安全的个人防护设备。使承包商和/或员工尽可能安全，为预防与光伏系统相关的危险和坠落风险做好准备。操作规程的范围包括电缆运营商中部署的并网和独立于电网的太阳能光伏系统？中国的基础设施。

This document provides recommended best practices for photovoltaic system operations and maintenance. This guide may not include all operations and maintenance routines or scenarios, but provides general guidance for safety practices, management, operations, and preventative maintenance of PV systems.Solar Photo Voltaic (PV) power generation systems in cable facilities are becoming more prevalent. There are several factors impacting the deployment of these PV systems including, high cost of electricity, reduced reliability of the electrical grid, national, state and utility incentives, carbon reduction and sustainability goals. Solar PV is operational during daylight hours for base, intermediate or peak load power generation replacing kW/MW normally supplied by the local utility.PV power generation systems are typically deployed to reduce the amount of power consumed that is generated from burning fossil fuels and increase the amount of power consumed by renewable energy sources. Most PV systems can reduce grid dependency with the addition of energy storage and provide relief for the electrical grid during high consumption periods. When electrical grids are under the most strain due to high consumption is also the time period the solar systems are operating at peak output.Key components of PV Systems include:• Roof or ground mounted Direct Current (DC) power generating photo-voltaic panels• Direct Current (DC) to Alternating Current (AC) inverters• Electrical distribution systems• Kilowatt hour (kWh) and current (amperes) metering and monitoring• Electrical distribution system disconnects and breakersRoof mounted PV systems are the most deployed systems at cable facilities. Ground mounted systems utilize valuable ground space and, in most locations, facility ground space is limited. Utilization of reclaimed ground space, such as decommissioned satellite dish space, is an option for deploying ground mounted systems.PV systems require periodic, scheduled maintenance to maintain reliability and operational efficiency. One of the most important areas of an O&M program is safety. Only qualified and trained personnel or contractors should be permitted to service or maintain PV systems. The most dangerous parts of a solar electric system is the electricity generated by the PV system. Personal protective equipment for arc-flash protection, lock-out/tag-out procedures, and rooftop safety are required when working around PV systems. Keeping contractors and/or employees as safe as possible by preparing them for prevention of hazards and fall risks associated with PV systems.The scope of the operational practice covers grid tied and grid independent solar photovoltaic systems deployed in cable operator?s infrastructure.
