| Abstract: | Aiming at the problem that some results of power system on-line security analysis andearly warning system can not meet the requirements of guiding on-line operation, a practical algo-rithm is proposed for on-line analysis of transient stability curve, on-line identification of small sig-nal stability oscillation mode, on-line identification of weak points of voltage stability and on-line search of dangerous cross-section. The actual system application results show that the algorithm hasachieved good results and can provide on-line decision-making basis for power network dispatchingoperators. |
