Abstract

Abstract:

During receiver commutation failure of HVDC transmission system， more reactive power were absorbed in a short time by rectifier converters from transmitter system， and the voltage stability or protection misoperation might appear in weak transmitter system or other disadvantage conditions. Taking Yindong HVDC transmission project as example， this paper analyzed the response characteristics of DC system after receiver commutation failure， studied the fault coupling mechanism of transmitter system and receiver system caused by the commutation failure of inverter station， and presented the reasons and phenomenon of voltage fluctuation in condition of weak transmitter system through simulation. The conclusions have important guiding significance to the commissioning of DC transmission project and the dispatching operation of AC grid.

Key words: HVDC transmission system, transmitter system, converter, commutation failure
