The Influence of Commutation Failure Predictive Control on Voltage Stability and Optimization Measures

For DC fed into the receiving end grid, avoiding commutation failure and maintaining voltage stability are two important issues. In order to reduce the risk of commutation failure, the actual DC control system is usually equipped with a commutation failure prediction control function module. In the disturbance process, predictive control reduces the firing angle α of the inverter to increase the c...
