Method for improving voltage of rural power grid
2016
The invention discloses a method for improving the voltage of a rural power grid. The method mainly comprises the steps: measuring the voltage value of a line through a voltage detection device; controlling an IGBT conduction angle of a DC chopper circuit in a voltage conversion output circuit and a conduction angle of an IGBT in an inversion circuit through a voltage regulator, thereby achieving the increase of a voltage, and counteracting the voltage loss in a transmission process. The method provided by the invention is convenient and flexible in voltage regulation, does not need to additionally replace a transformer and a power line, is convenient to install and debug, and is small in investment.
