<p>Method of compensation of reactive power in an alternating current power line The invention relates to electrical engineering and, primarily to methods and devices for compensation and controlling power factor in converters or inverters and particularly deals with methods for compensation of reactive power in. power lines of. industrial enterprises or individual consumers of this power, used for meeting the requirements of a power supply system for reactive power consumption. The claimed method lies in providing each feeder of a power line with a current converter bridge 2 having, in the input circuit at the side of the power line (1), at least one capacitor (3) and in passing the output current of the current converter bridge (2) through a load controlling the current passing through this capacitor (3). The novel feature of the method is that at feast one light-emitting diode (6) is used as a load. Various modifications of the present method are disclosed which allow optimizing the compensation process. In the course of use of the claimed method for compensation of reactive power in consumer's power line, inductive reactive power is compensated with capacitive reactive power of a lighting source, thus the power factor (Cos phi) increases, and, at the same time, due to light emission by the light-emitting diodes, the compensator serves as a general lighting source.</p> |
