Control of the propeller electric drive under restrictions imposed on the power plant capacity in the unified power system

Abstract

The article proposes a method for adaptive control of a rowing electric drive in a single electric power system under restrictions imposed on the power generated by a marine power plant. The adaptability of the control consists in changes in the magnitude of the permissible electromagnetic torque depending on the "free" power generated by the power plant and the required rotational speed, as well as the power on the propeller. The proposed method of adaptive power limitation by limiting the magnitude of the electromagnetic moment allows the electric drive to operate in both static and dynamic operating modes. Such control will make it possible to limit the power consumed from the power plant at a level not exceeding its current set value, and, as a result, to eliminate its overload and the possible occurrence of emergency situations. In addition, such control will automate the operation of power generating systems of the power plant, ensuring their commissioning or decommissioning, depending on the current capacity required by consumers of electric energy. Such management will ensure that the operating power generating systems of the power plant are loaded with a total capacity close to the installed capacity, which will also have a beneficial effect on the operating life of the power generating systems of the power plant. In addition, the proposed method of controlling a propeller electric drive, in addition to rational utilization of energy sources, will ensure high efficiency and reduce operating costs, and improve the quality of electromagnetic processes in a single electric power system.
