description | The invention provides a power factor control method and device applied to a transverter, and aims to control the power factor so as to obtain a reactive power reference value; the method comprises the following steps: setting a power factor reference value, solving difference between the power factor reference value and a power factor actual measurement value, carrying out PI adjustment so as to obtain the reactive power reference value, and adding the reactive power reference value with the reactive power setting value so as to obtain the final reactive power reference value; carrying out reactive power adjustment on the reactive power reference value so as to obtain the current reference value. The method can adjust the power factor of a transverter AC access point, thus increasing the transverter control function, and the control function is more flexible, thus applying to various application scenes; the power factor control method can lift the power factor of the access point without adding an AC filter, |
