A method and controller of dynamically determining a current system curve in a heat power system, in which the heat power system comprises a regulator and sensors. The controller controls an output of the regulator to find the current system curve, collects and checks sensor values with limited accuracy to determine if properties of the sensor values indicate that a point of the current system curve has been reached. When at least two points are found the controller models the current system curve by linear interpolation between the first and second point of the current system curve.

Method and controller for dynamically determining a system curve in a heat power system

A method for preventing formation of droplets in a heat exchanger, in which a second medium transfers heat to a first. The method is performed by a controller which receives different temperature values (T, T, T) and a pressure (P) value to be used for calculating a boiling point temperature value (T) and determining a first temperature difference (&#x394;T) and a second temperature difference (&#x394;T). Generating a flow control signal, for controlling the flow of the first medium into the heat exchanger, based on the first temperature difference (&#x394;T), the second temperature difference (&#x394;T) and the first temperature value Tand sending the flow control signal to a regulator device for controlling the flow of the first medium in the heat exchanger.
