计及其波动的无功功率考核方法

针对现行的均权平均功率因数考核方法不能反映用户无功功率负荷特性，不能对影响电能质量的用户加收改善电能质量的电费问题，提出了一种基于波动系数的无功功率考核方法。该方法通过动态无功补偿装置或专用的无功检测设备，记录无功功率的变化规律，根据设定的无功功率允许波动范围，将超出范围的不同时段无功功率波动陡度系数与幅度系数乘积的和定义为无功功率波动系数。采用无功功率波动系数与均权平均功率因数共同对用户的无功进行考核，促使用户主动改善电能质量，提高电能的使用效率。

Estimated Means of Reactive Power Considering its Fluctuation

The paper analyses the defect of the eastimated means by which the reactive power is eastimated using average power factor.The concept of the modulus on reactive power fluctuation is proposed.On the basis of the concept,a new eastimated means of reactive power considering the fluctuation of reactive power is proposed.The new eastimated means not only overcomes the defect,but also urges the users of electric power to improve the quality of electric power.
