摘要
随着清洁能源不断发展,兴安地区作为清洁能源汇集基地已无法全部消纳本地的清洁能源,过多的光伏、风电等需通过500kV兴安变电站的变压器上送至500kV电网进行远距离输送。因此变压器容量及其过载能力成为限制清洁能源接纳的主要原因。以兴安电网为例,分析了变压器过载能力,研究利用变压器过载能力提高电力输送的安全限额,加大清洁能源接纳水平。
With the continuous development of clean energy, as a base of clean energy convergence, Xing an area has been unable to absorb all the local clean energy. Excessive photovoltaics and wind power need to be transferred to 500 kV power grid through transformers of 500 kV Xing an substation for long-distance transmission. Therefore, the capacity and overload capacity of the transformer become the main reasons for restricting local clean energy. Taking Xing an power grid as an example, it puts forward a measure to improve the limit of power grid by using the overload capacity of transformers, and then enhances the capacity of clean energy acceptance.
