Analysis of the Impact of “Strong DC and Weak AC” on the Stability of the Receiving-end Power System

摘要：

　　The rapid development of UHVDC transmission project has brought abundant power supply to the receiving-end power system area,but there are still many security and stability problems.The paper summarizes the four elements that affect the strength of the AC system,and then simulates the most basic two-terminal single-pole UHV transmission system by MATLAB/Simulink.It analyzes the impact of receiving-end AC power system strength at real-time power,frequency and voltage.Finally,in view of to the operation risk of ”strong DC and weak AC” grid pattern,three countermeasures are put forward.
