A Multi-Objective Assessment for Primary Frequency of Generator

Abstract:

The ability of the generator unit response frequency change is the key issue of assessing primary frequency regulation. Meanwhile, the setting of speed regulating system parameter greatly affects primary frequency performance of generators. Therefore, this paper proposes a comprehensive evaluation system, which can comprehensively analyze and evaluate the ability of primary frequency regulation from various aspects. It combines speed regulating system parameter index with common evaluation index. In this part, the author puts forward a multi-objective assessment algorithm. Firstly, when generators experienced disturbances, collect the corresponding data of plant and system. Then the speed regulating system parameter is estimated by the actual accident of generator. Besides, the common evaluation index is calculated, including the contribution electric quantity, response time, delay time and the contribution ratio. Finally, the algorithm is applied to the actual hydro power units and thermal power units, and the results illustrate the feasibility and reliability of the algorithm.
