Abstract
This paper focuses on the stability analysis and control strategy of HVDC transmission system. Firstly, the definition, characteristic and system composition of HVDC are summarized and its important position in modern power transmission is defined. Subsequently, the driving role of HVDC system stability on system reliability, economy and clean energy transmission is discussed in detail, and it points out that stability is the key to ensure the efficient operation of the system. In the stability analysis section, the paper focuses on the influence of load change, reactive power balance, power stability and frequency stability on the system, and reveals the key role of these factors in the dynamic behavior of the system. Finally, for the stability control strategy, this paper proposes to improve the self-regulation ability and integrity of the system by adjusting the voltage regulator parameters, optimizing the trigger Angle, establishing a perfect safety control system and dynamically adjusting the transmission power. These research results not only provide theoretical support for the design and optimization of HVDC transmission system, but also provide useful reference for the realization of intelligent, efficient and clean operation of the power system, and help to promote the sustainable development of the power industry.
