摘要

研究了长距离交流输电中有功功率损耗的组成。结果表明，在低负荷和中等负荷模式下，电晕损耗是损耗的主要份额。目前确定电晕功率损失的方法的缺陷，本质上是气候性的，决定了在计算负载功率损失后将这些损失从总损失中分离出来的方法。得到了确定有功功率负载损耗的四分量公式。结果表明，为了澄清计算模型，有必要考虑电线的实际温度，并考虑线路沿线天气条件的变化。给出了2021年9月13日白天750 kV架空输电线路“Zakhidnoukrainska-Vinnytska”有功功率损耗分量的计算结果。参考文献9，图4，表3。

DETERMINATION OF ACTIVE POWER LOSSES COMPONENTS IN LONG-DISTANCE AC POWER TRANSMISSION

The components of active power losses in long-distance AC power transmission are investigated. It is shown that in the modes of low and medium loads the main share of losses are corona losses. The imperfection of the current method of determining the corona power losses, which are climatic in nature, determines the method of separating these losses from the total after calculating the load power losses. A four-component formula for determining the load losses of active power is obtained. It is shown that to clarify the calculation model it is necessary to take into account the actual temperature of the wire, taking into account changes in weather conditions along the route of the line. The results of calculation of components of active power losses in the 750 kV overhead transmission line "Zakhidnoukrainska-Vinnytska" during the day of September 13, 2021 are given. References 9, figures 4, tables 3.
