Design of Hardware-in-the-loop Real Time Simulation System for Tidal Turbine Control System Based on RT - LAB

The horizontal axis tidal turbine could share part key components with the current mature wind turbine manufacturing industry, so it becomes a research hot spot of megawatt-level prototype. However, the operating conditions of the tidal turbine are special, the closed-loop simulation verification of the control system before the sea test of the prototype is directly related to the operational reliability of the prototype, so more and more attention is paid to it. Based on the advanced hardware real-time simulation system RT -LAB, the tidal turbine control system hardware-in-loop simulation system is designed. The digital closed-loop simulation system include a tidal velocity model, a hub torque model and a drive chain model, and is connected to the tested control system through hardware signal connections. It has a consistent interface with the prototype and has a high similarity. The digital hardware-in-the-loop system's configuration has strong flexibility, is suitable for controller simulation tests of tidal turbine with different power levels, and has good reliability and practicability.
