为明晰宁夏电网转供电量增加的过网网损,选取3个典型代表日,采用网损分摊算法计算并分析了±660 kV宁东直流外送电量对宁夏电网统计线损的影响.分析结果表明:宁东直流外送导致宁夏电网潮流分布发生变化,增加了网损电量,引起宁夏统计线损上升.
為明晰寧夏電網轉供電量增加的過網網損,選取3箇典型代錶日,採用網損分攤算法計算併分析瞭±660 kV寧東直流外送電量對寧夏電網統計線損的影響.分析結果錶明:寧東直流外送導緻寧夏電網潮流分佈髮生變化,增加瞭網損電量,引起寧夏統計線損上升.

In order to clear find the line loss of passing through Ningxia Power Grid due to increased transferr supply quantity of electric power, selecting typical representative 3 days and using apportion?ment method of line loss for power grid, calculates and analyzes the influence of ±660 kV Ningdong DC power transmission on statistic line loss of Ningxia Power Grid. The analysis result shows that Ning?dong DC power transmission bringing on the change of tide distribution and the increase of the line loss quantity in Ningxia Power Grid, resulting in the rise of statistic line loss in Ningxia Power Grid.
