探讨线路变压器单元接线的经济运行方式对降低网损、节约能源具有实际意义。基于线路变压器单元接线的等值电路和总损耗,采用数学极值方法推导出线路变压器单元接线经济运行功率的表达式,得出当线路变压器单元接线按经济功率运行时,其效率最高、线路损耗最小的结论,并通过算例说明了经济运行功率等有关指标的计算方法。研究分析结果为实际运行的线路变压器单元接线实现经济运行提供参考价值。
It is practical significance for the reduction of power grid loss and energy saving to discuss the economic operation mode of power line transformer unit connection. Based on the equivalent circuit and overall loss of power line transformer unit connection, the expression of the economic operation power of power line transformer unit connection is deduced by mathematical extreme method, which draws the conclusion that the power line transformer unit connection has highest efficiency and minimum power line loss when it is operating at economic power. Calculation methods of relevant index such as economic operation power are explained by examples. Study and analysis results provide reference value for the realization of economic operation of the practical operating power line transformer unit connection.
