Improving the efficiency and operation of power transmission is important due to the continual increase indemand for electric power. In addition, many remote areas throughout the world lack sufficient access to electricity.Unfortunately, utilities cannot satisfy the high demand of power by building new power stations because of economic andenvironmental reasons. However, utilities can increase generation and transmission line efficiencies by controlling thepower flow through their systems. One new attractive technology that enables the control of power flow in the system isVoltage-Source- Converter High Voltage Direct Current (VSC-HVDC) transmission. The contemplated protectionscheme provides advantages, such as lower dv/dt stresses and lower voltage rating of thyristor switches in accumulationto providing full segregation between the converter semiconductor devices and ac grid during dc-side faults. Asimulation case study has been carried out to reveals the effectiveness of the contemplated scheme.
