直流逆变端扰动对整流端影响机制及应对措施
Study on the Mechanism and Countermeasures of the Influence of Disturbance at Inverter Side on the Rectifier Side
摘要
Abstract
Due to the increasing high voltage direct current (HVDC) transmission capacity, the interaction degree between ac system and HVDC had aggravated, the mutual influence between the sending and receiving end of HVDC cannot be ignored. The asynchronous interconnected ac system by HVDC was established firstly. The dynamic response trajectory of converter firing angle and dc current was studied during the ac voltage at receiving end changing at different rate and the mechanism of disturbance propagation by HVDC was revealed. During the disturbed process, the transient power response characteristic of rectifier station was revealed, and the influence factors such as the strength of ac system, the setting value of controllers and so on were considered. On this basis, aiming to the overvoltage threaten occurred during Hami-Zhengzhou UHVDC receiving end fault, the mitigation measures that reinforcing ac network or optimizing the steady-state reactive power configuration are proposed, and simulation results verify the validity.关键词
