MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202531116052 A) filed by National Institute Of Technology, Rourkela, Orissa, on Nov. 24, 2025, for 'system and method for real-time wind turbine emulation using buck-converter-driven dc machine and digital controller.'
Inventor(s) include Pattnaik, Dr. Monalisa; Mishra, Dr. Jyotismita; and Behera, Dr. Pradyumna Kumar.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a wind turbine emulator (WTE) system (100) and method (200) configured to reproduce aerodynamic and dynamic behaviour of a real wind turbine for laboratory testing. The system (100) comprises a mechanical actuator (1) coupled to a generator shaft and driven through a power converter stage (5). A digital turbine emulation controller (2) computes a reference mechanical torque based on wind speed and measured shaft speed, while a torque regulation module (3) performs current-mode control to ensure accurate torque tracking. A pitch controller (4) modifies a power-coefficient function to emulate turbine power regulation. An electrical loading interface (6) extracts electrical power from the generator-under-test, enabling wind and load variations to be reflected in torque-speed behaviour. Closed-loop coordination of actuator (1), controller (2) and loading interface (6) provides high-fidelity turbine emulation. The present invention is applicable for testing MPPT strategies, drive-train validation, and grid-compliance studies."
