Аннотация: The article reviews the interrelation between reactive power compensation and electrical power quality by the indicator of voltage deviation. The trend towards the introduction of innovative technologies in recent years has a negative impact on the operation of electrical grids. In connection with steady decrease of power factor due to the use of modern electric devices, there is an increasing need for effective compensation of reactive power in residential low-voltage electrical grids. The purpose of the article is to develop an effective method and means of reactive power compensation in residential low-voltage electrical grids. The use of known capacitor batteries with symmetrical compensation is inefficient due to unbalanced load on phases in grids with grounded neutral mode. The operation principle of independent individual reactive power phase compensation device is demonstrated. The results of introduction of independent reactive power compensation devices by phases into experimental operation presented in this article prove their high efficiency. The presence of higher current and voltage harmonics in residential electrical grids necessitates the use of special means of protection against their impact on capacitor batteries. © 2020 IEEE.
