Abstract

The invention relates to the technical field of a solar power supply system, and specifically relates to a power factor calibration controller for a solar power station, solving the defects that a current power factor controller existing in the prior art, has a single compensation function, and cannot easily update the internal control information, and has single calibration mode, thus being unable to satisfy the application demand for the current power supply system for a solar power station. The power factor calibration controller for a solar power station includes a main control module, a metering module, a comparison module, a data storage module which is used for storing the inherent internal equipment information, an external communication module which is used for updating the storedinformation of the data storage module, and a calibration module which is used for operating and calibrating the electric energy quality situation and the conditions of temperature and humidity. Thepower factor calibration controller for a solar power station has the advantages of improving the reliability of reactive power compensation, being diversified in the manner of calibration, improvingthe service life of the device, being able to carry out update and learning of the internal control information through the external communication module conveniently, and being diversified in the functions of the device.

Description

technical field [0001] The invention relates to the technical field of solar power supply systems, in particular to a solar power station power factor calibration controller. Background technique [0002] The power factor controller is a real-time detection system for the controller, which is used to control the switching of the capacitor bank and applies a reactive power compensation cabinet. In the existing power supply system of solar power plants, various equipment will generate various reactive power losses due to coil current, which will reduce the power factor of the point, resulting in waste of electric energy and affecting power supply. [0003] In order to solve these losses, a power factor calibration controller will be set to minimize the loss of the power grid and improve the quality of the power grid. However, today's power factor controllers have a single compensation function, cannot easily update internal control information, and have a single calibration m...
