【Abstract】 This Paper briefly describes the technical and economical advantages and the problems of the replacement of the controlled converter at the sending end by a diode-rectifier. The discrete-time state equatons describing the dynamic performance of the HVDC transmission system are derived, also a set of calculation formulas analyzing the small signal stability of the system by using the Routh Criterion via a transmission. The situation of the system stability of an engineering Project is examined under the conventional excitation condition of the generators supplying the diode-rectifiers. The effects of several. Parameters on the system stability are evaluated.更多还原
