Abstract
A method determines an operating state of a transformer located in a high-voltage network. The method includes obtaining measurement values from sensors located in or on a power transformer. The measurement values are used to obtain a liquid temperature measurement of the insulating liquid. The measurement values are supplied to a thermohydraulic simulation model. The thermohydraulic simulation model then determines the operating state of the transformer by providing simulated state parameters which represent the operating state of the transformer. A parameter is an insulating liquid temperature state parameter which corresponds to a temperature value simulated for the insulating liquid. It is desirable to take weather influences such as wind or rain into account. A controlled system is connected upstream of the thermohydraulic simulation model and determines a control deviation formed from the difference between the liquid temperature measurement value and the corresponding simulated insulating liquid temperature state parameter.
