小水电发供分离的技术原则分析

Analysis of Technical Principles for Separation of Small Hydropower Generation and Supply

介绍小水电并网对配电网的影响,指出对小水电进行发供分离,可从根本上解决发供共线造成的过电压问题,认为小水电发供分离能有效提高配电网供电可靠性,降低小水电引起的电压波动对配电网的影响,明确了小水电进行发供分离的技术原则。

This paper introduces the impact of small hydropower grid connection on distribution network.It is pointed out that the separation of small hydropower generation and supply can fundamentally solve the overvoltage problem caused by the co-line of generation and supply.The separation of small hydropower generation and supply can effectively improve the power supply reliability of the distribution network and reduce the voltage fluctuation caused by small hydropower.The technical principle of separation of power generation and supply for small hydropower is clarified.
