如果你所在的城市常年霧霾、陰雨、或者冰雪天氣，光照條件差，那么發電效率也會降低，對于那些想要節省電費、獲得收益的人來說，這樣的地區就不適合建立電站了。下面天合藍天來講講光伏發電電站接入電網用電要滿足的條件。

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、光伏發電電站須在逆變器輸出匯總點設置易于操作、可閉鎖、且具有明顯斷開點的并網總斷路器，以保證電力設備檢修維護人員的人身安全。

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、光伏發電電站和并網點設備的防雷和接地應符合電網公司規定要求，光伏發電電站接地網接地電阻合格，接地電阻應按規定周期進行測試。

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、光伏發電電站或電網異常、故障時為保護設備和人身安全，應具有相應繼電保護功能，保護電網和光伏設備的安全運行，確保維護人員和公眾人身安全。光伏發電電站的保護應符合可靠性、選擇性、靈活性和速動性的要求。

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、光伏發電電站的過流與短路保護、防孤島能力、逆變率保護、恢復并網等應滿足電網規定的要求。

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、光伏發電電站的二次用直流系統的設計配置及蓄電池的放電容量應符合相關規程的技術要求。

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.

光伏發電電站的電能質量滿足規程要求，電壓諧波和波形畸變、電壓偏差、電壓波動和閃變、電壓不平衡度、直流分量在規定的范圍內。更多相關的內容就來我們網站http://m.51dwgw.cn進行咨詢吧！
