In order to avoid safety accidents, a series of preparatory work will be strictly done when carrying out the conceptual design and equipment selection of the power station.

一 ：分析安装分布式光伏发电系统

1： Analysis and installation of distributed photovoltaic power generation system

的载体建筑，做好合理安全的空间规划，必须安排专门的空间区域放置光伏组件和逆变器等设备，尽量避免非人员接触发电设备，以免引发安全事故。

For carrier buildings, reasonable and safe spatial planning must be made. Special spatial areas must be arranged to place photovoltaic modules, inverters, and other equipment, to avoid non professional personnel from contacting power generation equipment as much as possible, in order to avoid causing safety accidents.

二：对选用设备的品质和产品认证齐备情况进行充分的了解，确认逆变器所获得的认证证书和认证质量，不仅需要将EMC(电磁兼容)问题作为重要考虑内容，必要时要采用相关的辅助措施，以防出现发电设备对原有电子设备的电磁干扰，同时还需要在逆变器输出汇总点设置易于操作、可闭锁、且具有明显断开点的并网总断路器，以确保电力设施检修维护人员的人身安全，杜绝可能出现的孤岛效应。

2： To fully understand the quality of the selected equipment and the completeness of product certification, and confirm the certification certificate and quality obtained by the inverter, it is not only necessary to take EMC (electromagnetic compatibility) issues as an important consideration, but also to adopt relevant auxiliary measures when necessary to prevent electromagnetic interference from the power generation equipment to the original electronic equipment. At the same time, it is also necessary to set up an easy to operate, lockable The main circuit breaker connected to the grid with obvious disconnection points is provided to ensure the personal safety of maintenance personnel of power facilities and eliminate the possible island effect.

三：在完成以上要求的基础上，对防火、接地、应对强风方面加大防护力度。

3： On the basis of completing the above requirements, strengthen protection against fire, grounding, and strong winds.

四：另一方面，在分布式光伏发电系统的正常运行过程中，要坚持对发电系统进行安全性定期检查，同时不断提高分布式光伏发电系统的智能化运维能力，将所有可能出现的安全故障一时间得到反馈，在保证发电效率的同时提高整个系统的安全性。

4： On the other hand, during the normal operation of a distributed photovoltaic power generation system, it is necessary to adhere to regular safety inspections of the power generation system, while continuously improving the intelligent operation and maintenance capabilities of the distributed photovoltaic power generation system, providing timely feedback on all possible safety failures, while ensuring power generation efficiency and improving the safety of the entire system.

具体来说，除了基本的消防安检措施外，还特别要求光伏系统具备自我检测、识别异常并主动停止异常发电组串工作的功能，降低火灾发生可能性。发电系统的任何一个环节，光伏组件、组串汇流、逆变设备等，都可以作为这一智能自检自控功能的加装应用载体

Specifically, in addition to basic fire safety inspection measures, photovoltaic systems are also specifically required to have the ability to self detect, identify anomalies, and actively stop the operation of abnormal power generation strings to reduce the likelihood of fire. Any link in the power generation system, such as photovoltaic modules, string combiner, and inverter equipment, can be used as an additional application carrier for this intelligent self inspection and automatic control function

分布式光伏发电在总体上的安全性是值得信赖的，随着行业标准和规范的不断提高，分布式光伏发电因为设备质量问题、设计建设问题而导致的安全隐患必然会越来越少，但是因为其自身发电模式的特殊性，还是需要业主关心分布式光伏发电系统的整体安全性能，养成定期维护的良好习惯。

The overall safety of distributed photovoltaic power generation is trustworthy. With the continuous improvement of industry standards and specifications, there will inevitably be fewer and fewer potential safety hazards caused by equipment quality issues and design and construction issues in distributed photovoltaic power generation. However, due to the particularity of its own power generation mode, it is still necessary for owners to care about the overall safety performance of distributed photovoltaic power generation systems and develop a good habit of regular maintenance.
