如果你所在的城市常年雾霾、阴雨、或者冰雪天气，光照条件差，那么发电效率也会降低，对于那些想要节省电费、获得收益的人来说，这样的地区就不适合建立电站了。下面
金佰利中国蓝天来讲讲光伏发电电站接入电网用电要满足的条件。
If you live in a city with smog, overcast rain, or ice and snow all the year round, and poor lighting conditions, the power generation efficiency will also be reduced. For those who want to save electricity bills and obtain benefits, such areas are not suitable for building power stations. Next, Trina Solar Blue Sky will talk about the conditions that PV power stations need to meet to access the power grid.
1、光伏发电电站须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，以保证电力设备检修维护人员的人身安全。
1. The PV power station must set up a grid connected main circuit breaker at the inverter output summary point that is easy to operate, lockable, and has obvious disconnection points to ensure the personal safety of power equipment maintenance personnel.
2、光伏发电电站和并网点设备的防雷和接地应符合电网公司规定要求，光伏发电电站接地网接地电阻合格，接地电阻应按规定周期进行测试。
2. The lightning protection and grounding of photovoltaic power station and grid point equipment shall meet the requirements of the State Grid Corporation of China. The grounding resistance of the grounding grid of photovoltaic power station shall be qualified, and the grounding resistance shall be tested according to the specified period.
3、光伏发电电站或电网异常、故障时为保护设备和人身安全，应具有相应继电保护功能，保护电网和光伏设备的安全运行，确保维护人员和公众人身安全。光伏发电电站的保护应符合可靠性、选择性、灵活性和速动性的要求。
3. In order to protect equipment and personal safety in case of abnormality and fault of photovoltaic power station or grid, it shall have corresponding relay protection function to protect the safe operation of grid and photovoltaic equipment and ensure the personal safety of maintenance personnel and the public. The protection of photovoltaic power station shall meet the requirements of reliability, selectivity, flexibility and quick action.
4、光伏发电电站的过流与短路保护、防孤岛能力、逆变率保护、恢复并网等应满足电网规定的要求。
4. The over-current and short circuit protection, anti islanding capability, inverter rate protection, restoration of grid connection, etc. of the photovoltaic power station shall meet the requirements of the national grid regulations.
5、光伏发电电站的二次用直流系统的设计配置及蓄电池的放电容量应符合相关规程的技术要求。
5. The design configuration of the secondary DC system of the photovoltaic power station and the discharge capacity of the battery shall comply with the technical requirements of relevant regulations.
光伏发电电站的电能质量满足规程要求，电压谐波和波形畸变、电压偏差、电压波动和闪变、电压不平衡度、直流分量在规定的范围内。更多相关的内容就来我们网站
