ADJUSTABLE REACTIVE POWER COMPENSATOR

摘要

The adjustable reactive power compensator relates to electrical engineering and electrical energy industry and can be used for reactive power compensation both separate receivers and network reactive power. The device includes: a bank of capacitors, a phase number converter, series connection of an inductance choke and a semiconductor switch to each of parent phase. The bank of capacitors is connected to the three-phase network, the phase number converter inputs also being connected. The outputs of this converter are connected in-series connections of an inductance choke and a semiconductor switch. Number of in-series connections of an inductance choke and a semiconductor switch is equal to number of output phases of converter phase number. Increase of output phase number in the controlled reactive power compensator allows increasing compensator speed of response by an order of (up to 12-15 ms). By means of such compensator one can remove voltage fluctuations in consumer devices in the networks.
