Emergency power source current conversion device for nuclear power station and control method

Abstract

The invention provides an emergency power source current conversion device for a nuclear power station and a control method, applicable to the technical field of nuclear power station current conversion. The emergency power source current conversion device for the nuclear power station comprises multiple current conversion units, a sampling unit, a plurality of built-in controllers and a central controller. The built-in controllers make the multiple current conversion units synchronously work in current equalization and voltage stabilization under the control of the central controller. When one current conversion unit stops working due to faults, other current conversion units can still normally work independently, so that the reliability of the emergency power source current conversion device for the nuclear power station is improved. The emergency power source current conversion device for the nuclear power station is designed in a modular manner and is convenient to expand, the capacity of the emergency power source current conversion device for the nuclear power station is enhanced, and meanwhile, online replacement and maintenance can be realized. In addition, in the invention, an anti-seismic structure is adopted for the emergency power source current conversion device for the nuclear power station. The anti-seismic structure has excellent anti-seismic performance and can ensure that the emergency power source current conversion device works normally during earthquakes.
