Analysis of Safety and Stability on Sending and Receiving Ends of ±500kV DC

Abstract

The operation of HVDC transmission project shortened the transmitting distance between two power networks. While the change of power networks frame brought new diversification in the safe and stable operation of the sending and receiving ends of HVDC transmission. In this paper, ±500kV Jinzhong DC transmission project was taken as an example. By using PSD-BPA electromechanical transient software to simulate and analyze the sending and receiving ends faults after the operation of HVDC transmission, the influence of HVDC transmission project on the sending and receiving ends dynamic characteristics and the existing operational risk was studied. And then, corresponding control measures were put forward.
