Abstract This paper proposes an algorithm for the revising of the parameters of load model of substation in different periods during a day. Firstly the ability in extracting load characteristic of different kinds of feature parameters are analyzed through qualitative analysis and measured active power is chosen as the characteristic parameter when takes modifying model parameters in different daily periods into consideration. Secondly, on the basis of the clustering centers of substations and synthesis daily load profiles of typical industries, the weight of every parameter in different daily periods is calculated via super weighting method. Then the real time synthesis load proportion of classical industries is computed based on the single element judgement sets in different daily periods and the weight of the parameters which corresponds to the same period by means of fuzzy comprehensive judgement. At last, the load model parameters of substation in different daily periods is worked out through combining the real time proportions and typical industrial parameters which are derived by other methods. The algorithm proposed by this paper is compared with the method which is based on the whole daily load profile and with the traditional component-based approach method respectively, the results show that it is rational and effective.

Key words： Load modeling on-line revising daily load profile fuzzy synthesis discrimination
