摘要

将考虑中性点导体功率损耗的视在功率新公式与标准公式进行了比较，得出了两者等效的条件。建立了视在功率的一种新的物理意义，视在功率是供电系统的功率损耗和反向短路功率的几何平均值。分析了基于视在功率新确定的并联有源滤波器控制策略的节能优势。推导了并联有源滤波器提高电力系统效率的能量可行性的分析条件。

The new formula for apparent power and power losses of three-phase four-wire system

The new formula of the apparent power, which takes into account the power losses of the neutral conductor, has been compared with standardized one and conditions of their equivalency were found. A new physical sense of apparent power was established, it is a geometric mean value of power losses and reverse short-circuit power of supply system. The energy saving advantages of new control strategy of shunt active filter based on new determining of apparent power were shown. Analytical condition for the energy feasibility of a shunt active filter to increase the efficiency of the power system has been derived.
