Research On Criteria Of Asynchronous Oscillation Based On Compensation Theory

Systematic researches on new criteria of asynchronous oscillation based on compensation theory are carried out in this paper. The necessity of research on the new criteria is explained and a new asynchronous method based on compensation theory is proposed, which is dependent upon existing out-of-step criteria of power system. Furthermore, digital simulation is carried through on multi-stage voltage compensation components and their performances about various short circuit faults are analyzed. According to the proposed criteria, the improved equipment of system splitting based on compensation theory is exploited on the basis of existing hardware. Applying the judgement method of line commission, the equipment has capable of adapting change of systematic operation modes.Shao Junsong (Power System and its Automation)Directed by Prof. Li Gengyin and Prof. Sun Guanghui...
