Title:
A METHOD FOR ENERGY EFFICIENCY AND AN EQUIPMENT OPERATING ACCORDING TO THIS METHOD
Document Type and Number:
WIPO Patent Application WO/2022/146340
Kind Code:
A3
Abstract:
In order to provide energy efficiency and/or low fuel consumption and/or reduction in emissions and/or maintenance costs, the invention relates to an equipment (10) and a power management method (100) for the efficient operation of said equipment (10), wherein the equipment comprises - at least two simultaneously synchronized energizers (10.1) comprising at least one propulsion (10.10), at least one rotating electrical machine (10.11) which is synchronous or asynchronous or permanent magnet suitable for the inverter application, at least one inverter (10.12) which applies the reverse torque to the rotating electrical machine (10.11) and enables the energy (regenerative energy) released as a result of braking to be used, at least one control unit (10.13) comprising at least one human-machine interface (10.130) which enables monitoring the measurements of the propulsion (10.10) and electrical machine (10.11) and inputting the torque / speed curves, system alarms and other parameters (safety margin, reserved power amount, machine ramp speed time, virtual timers) to the system, at least one power management system (10.2) comprising at least one control unit (10.20) which generates a start or stop signal between the diesel energizers (10.1) depending on the load (10.4) that it measures, at least one energy distribution element (10.3), at least one load (10.4) comprising at least one inverter (10.40) with at least one rectifier and at least one grid converter (10.41) to drive any motor such as a propeller and/or fan motor and/or pump motor at variable speed and/or at least one energy storage unit (10.5), and the control units (10.13 and/or 10.20 and/or 10.42) which control said load (10.4) and energizers (10.1) and provide the communication therebetween, and which enable to energize the energizers (10.1) with the synchronized and variable speeds and also at a predetermined DC constant voltage value without breaking the capacitors by adjusting the low dv/dt ratio according to the total capacitor value in the energy distribution element (10.3) through the bridge rectifier (full bridge diode rectifier) in the inverter (10.12) and by controlling the excitation of the energizer (10.1) and gradually increasing the voltage value in the energy distribution element (10.3) from zero with the electrical energy previously produced with the help of the reverse diodes in the converter (10.41) without using any pre-charge circuit and/or any external energy source, and which perform the most optimal sharing of the load (10.4) between said energizers (10.1) by the DC voltage droop method as the load (10.4) increases, and which activate/deactivate at least one of the energizers (10.1) depending on the increase/decrease of the load (10.4), and determine the optimal speed in any of them by using the speed/torque curve so that they can provide the required power, and transmit it to the energizer (10.1) as the speed reference, and thus enable the related energizer (10.1) to have a variable speed by controlling the speed with the communication therebetween.
