小水电对35kV变压器设备利用率的影响评估

Impact Assessment on 35 kV Transformer Equipment Utilization with Small-Hydropower

提出了结合负载率和负荷率两个指标评价35 k V变压器设备利用率的观点,考虑到35 k V变压器所在的小水电配电网的特殊性对两个指标进行细化。根据变压器运行数据对比了细化后的指标,得出采用双向计算后能较为客观地体现出35 k V变压器设备的利用情况的结论。研究成果可为评价含小水电配电网的35 k V变压器利用率提供新的角度。

The view of combined with the load rate and the burden rate two indicators to evaluate35 kV transformer equipment utilization is put forward, and the two indicators are detailedconsideringthe particularity ofsmall-hydrepowerdistribution network with 35kV transformer. Detailed indicators are compared according to the transformer operation data, then the conclusion of adopting bi-directional calculation can more objectively reflect the 35 kV transformer equipment utilization is drawn. A new perspective can be provided for using this research resultsto evaluate35kV transformer utilization of small-hydropowerdistribution network.
