The authors put forward a new method of analyzing low frequency oscillation based on energy coefficient. Through building energy function, the authors put forward concept of energy coefficient. Energy coefficient was used to analyze low frequency oscillation according to current working conditions; at the same time, the authors put forward concept of model en-ergy was used to analyze energy exchange of two generators. Through analyzing examples of power system, the authors proved correctness and effectiveness of the method in analyzing low frequency oscillation of power system.
