摘　　要：随着社会经济不断发展,生态系统被破坏的程度也越来越严重,不可再生能源在逐渐减少。而电力行业做为人们提供生产、生活重点的重要行业,其运作、发展一直是依靠不可再生能源,比如:煤炭等,但是,太阳能的广泛使用有效降低社会对于自然资源的索取度。在这样的背景下,电力企业开始也开始应用光伏电源。但是,就目前来看,光伏系统并网对配电系统继电保护及自动装置在成一定的影响。基于此,本文中笔者将从光伏发电系统原理入手,对光伏并网对配电系统继电保护及自动装置的影响进行分析,希望能够为读者提供有价值的参考。With the continuous development of the social economy, the destructiveness of ecosystem has become more and more serious, and non -renewable energy is gradually decreasing. As a key industry closely related to people＇ s life and production,the power industry＇ s operation and development have always been relying on non - renewable resources such as coal. However, the widespread use of solar energ7 has effectively reduced the social demand for natural resources. Under this circumstance, power companies begin to use photovoltaie power. However, as far as the current situation is concerned, the grid - connected photovoltaie system has a certain impact on the relay protection and automatic devices of the power dis- tribution system. Based on this, the author will start from the principle of photovoltaie power generation system, and analyze the impact of photovoltaie grid - connection on power distribution system relay protection and automatic devices, so as to provide valuable suggestions and referencesfor readers.
