Abstract :
The paper describes how an electromagnetic transient simulation program (EMTPDC) was used in the design of modifications to the controls of an HVDC converter that was experiencing commutation failures from AC voltage disturbances. These events were reviewed by the valve supplier and two control modifications were proposed. The purpose of the simulation study was first to reproduce measurements recorded at site, and then to select the best control strategy to eliminate the problem
