摘要
同频谐波电流、电压产生的谐波功率增大了电网的网损,而了解电网中谐波网损比例对于电力公司制定节能降耗的措施具有指导意义。比较分析了估算电网谐波网损方法的优缺点,并以实际电网和实测数据为基础,建立了计算谐波网损的简易模型,分析计算了电网谐波网损及其所占总网损的比例。通过对电网谐波网损进行论述表明了治理谐波及对谐波功率进行有效计量和收费的重要性。
Harmonic power which is caused by the same frequency harmonic current and voltage increases the loss of power system, and understanding the harmonic loss ratio of the power network has guiding significance for the power company to draw up conserve energy measure. This paper compares and analyzes relative merits of the methods of estimating power system harmonic loss and builds a simple model of calculation harmonic loss based on real power network and actual measured data. Harmonic loss and its share of total net loss ratio are analyzed in the paper. The net harmonic loss shows the importance of harmonics control and effective measures and charges for harmonic power.
