| Abstract: | Through the analysis of the simplified AC/DCinterconnected system model, the transmission capabilitiesof HVDC systems connected to weak AC systems have beenstudied in detail. The concepts and their computation algorithm of the maximum power curve, the maximum availablepower, the critical short circuit ratio and the boundary shortcircuit ratio are discussed. The strength classification of theconnected AC systems according to the critical short circuitratio and the boundary short circuit ratio is proposed in thispaper. |
