Research on Active Vibration Control and Environmental Performance Evaluation of Large Mechanical Grid Connected Systems

Abstract

Introduction: After the mechanical grid connected system is connected to the power grid, it may cause significant grid vibrations, which will have a certain impact on the environment and the stable operation of the mechanical system.

Objectives: In order to improve the stability of the power grid and the operational efficiency of machinery, this paper explores an active vibration control strategy for large-scale mechanical grid connected systems.

Methods: We provides an in-depth analysis of the characteristics of large-scale mechanical grid connected systems and constructs corresponding mathematical models to calculate system parameters accurately. Furthermore, we constructed mechanical vibration models under various modes based on the operating status, load conditions, and environmental factors such as temperature and humidity of the machinery. Based on this, we have designed a vibration control algorithm and its criteria for mechanical grid connected systems.

Results: The experimental results show that the vibration of the power grid is effectively controlled and does not exceed the safe range in these modes.

Conclusions: It can be seen that this control strategy enhances the stability of the power grid, and helps to improve the operational efficiency and environmental performance of mechanical systems.
