This paper introduces an analytical method of DC trip accident in Nan'ao VSC-MTDC Project. The inductive method is used to sum up the relevant factors, and then the possible fault causes are eliminated by deduction method, then assume the fault was caused by Valve control system. The correctness of the method and conclusion is verified by simulation experiments. The analysis can be used as a reference...
In multi-terminal VSC-HVDC system, The most important prerequisite to ensure stable operation of the system is to maintain stability of the DC voltage, a coordinated power control strategy applies to multi-terminal VSC-HVDC system is proposed in this paper. The proposed control strategy can make the converter stations controlled by multiple fixed-point DC voltage distribute the power reasonably according...
