More Information
Summary:The invention discloses a power frequency online anti-icing and de-icing method for a power transmission line, which comprises the steps which are as follows: three sets of dynamic reactive power compensation devices are connected with a power transmission line between a left side electric power substation and a right electric power substation which are adjacent; a temperature sensor is arranged on the power transmission line; when the temperature detected by the temperature sensor is lower than 0 DEG C, a controller controls the three sets of dynamic reactive power compensation devices into an anti-icing and de-icing working state; the reactive power compensation device at the left side generates a capacitive reactive current; the dynamic reactive power compensation device at the right side generates a capacitive reactive current; and the dynamic reactive power compensation device in the middle generates an inductive reactive current.
