Abstract
As an important way of modern power transmission, the control performance of the converter station directly affects the stability and efficiency of the whole system. This paper studies the control of HVDC converter station to improve the reliability and flexibility of system operation. Based on the shortcomings of the existing control strategy, this paper proposes a new control method of adaptive predictive control and fuzzy logic. This method adopts the real-time monitoring system state parameters and historical data, and effectively solves the problem of slow response speed and low accuracy. During the process of research, a detailed mathematical model was constructed to accurately describe the internal dynamic characteristics of the converter station, and the MATLAB / Simulink platform was used to build a simulation environment to comprehensively test the proposed scheme. The experimental results show that the new method can significantly improve the voltage stability, power regulation rate and fault recovery ability, and show excellent control effect under different load conditions.
