    摘要:

    针对某些跨省特高压线路在轻载情况下出现的统计负线损现象,考虑并分析环境温度对特高压线路计量的影响。以南阳—荆门特高压线路为例,建立温度对电容式电压互感器(CVT)等效分压电容影响的数学模型,并推导环境温度与CVT等效分压电容之间的关系。采用历史气温数据计算环境温度对CVT分压比的影响。算例分析表明,考虑CVT参数的差异,环境温度引起的CVT变比误差可能是线路出现统计负线损的一个原因。

    Abstract:

    Aiming at the abnormal phenomenon of negative statistical line loss occurring in some interprovincial ultrahigh voltage (UHV) transmission lines under light load, the influence of ambient temperature on measurement of UHV transmission line is analyzed in this paper. Firstly, the UHV transmission line of NanyangJingmen is taken as an example to establish a mathematical model of the influence of temperature on equivalent dividing capacitance of capacitor voltage transformer (CVT). Then, the relationship between the ambient temperature and the equivalent dividing capacitance of CVT is deduced. In the end, based on the historical temperature data, the influence of ambient temperature on the voltage division ratio of CVT is calculated. It is shown that the error of CVT voltage ratio caused by the environmental temperature may result in the negative statistical line loss of UHV transmission line when considering the discrepancies of CVT parameters.
