| 摘 要： | 分析了水布垭施工变电站功率因数低的原因,通过计算说明在长距离输电的情况下,线路产生的电容功率对无功平衡可能产生很大的影响,在负荷较小的情况下还可能向系统倒送无功.同时,变电站在不同的运行方式下,无功潮流分布差异很大.通过计算提出了在不同的运行方式、不同负荷水平下的无功补偿方案.

| Abstract: | The matter of why the power factor is lower than the normal value is analysed. The analysis result shows that under condition of long-distance transmission, the balance of reactive power may be influenced extremely by capacitive power occurred on transmission line, while under condition of low load, the reactive power may be transmited backward to system. In addition, under different operating patterns, the difference of reactive load flow distribution may be very large, therefore, the reactive power compensation schemes under different operating pattern and different load level are recommended. |
