Abstract: A method includes selecting the branch of a ventilation system with the greatest pressure loss, opening a control valve in the selected branch and closing control valves in all other branches, controlling a fan to produce the desired air flow rate into the selected branch by using fan characteristic shaft power to air flow rate curves, and a shaft power estimate from the frequency converter and by adjusting the rotational speed of an electric motor to achieve the desired air flow rate, calculating the fan pressure corresponding to the desired air flow rate from fan characteristic fan pressure to air flow rate curves, saving the calculated fan pressure as a reference pressure, and adjusting the control valves in each of the remaining branches so that the desired air flow rate to each branch is delivered while the fan is controlled by the frequency converter to produce the reference pressure.

Abstract: A method and an arrangement of determining inductances of a synchronous reluctance machine are provided. The method includes supplying a voltage pulse in the quadrature-axis or direct-axis direction of rotor, sampling currents generated by the supplied voltage pulse, and calculating values of flux at the sampling instants from the value of the supplied voltage pulse, the sampled current values and a value of the stator resistance. The method also includes calculating synchronous inductance of the machine by dividing the calculated flux values by the corresponding sampled currents, and/or calculating transient inductance of the machine as a derivative of the flux with respect to current, and storing the calculated values as a function of current.

Abstract: A DC current path for DC power transmission includes a switchable element. An inductance is connected in series to the switchable element. When an interrupt scenario is detected, a resonance circuit is connected in parallel to the series connection of the switchable element and the inductance for charging a capacitance of the resonance circuit. An open state of the switchable element is effected and the resonance circuit is connected in parallel to the switchable element. By means of such arrangement and method, favorable fast interrupt times can be achieved.
