摘要:
太阳能是人类取之不尽用之不竭的可再生能源，具有充分的清洁性、绝对的安全性、相对的广泛性、确实的长寿命和免维护性、资源的充足性及潜在的经济性等优点，在长期的能源战略中具有重要地位。本文综述电网中性点不同接地方式的比较，为光伏电站中性点选择合适的接地方式，并以某光伏电站为实例，计算中性点接地电阻值，以供以后的工程参考。
Solar energy is a kind of inexhaustibile clean energy. It has sufficient cleanliness, adequacy and potential economic security of absolute and relative breadth, really long life and maintenance-free property, resources etc., and plays an important role in the long-term energy strategy. In this paper, the comparison of different neutral point grounding modes of power network is summarized to select the appropriate neutral point grounding for the photovoltaic power station. Taking a photovoltaic power station as an example, neutral grounding resistor is calculated to offer the values for reference value in the future.
