The Design And Implement Of A Power System Stabilizer On Turbine Side

With the increase of the scale of electric power grid, the operational plan is becoming more and more complex, and the power system low frequency oscillation frequently. There are two main reasons for the low frequency oscillation, one is the negative damping of power system, which is widely accepted up to now, and another is forced resonance type. For the first reason, the measures of suppress low frequency oscillation are frequently used with power system stabilizer, static compensator and adopting the high voltage direct current transmission system. But, for the latter, which is caused by the turbine side still has not effective control measures.Based on the principle analysis of excitation side power system stabilizer and turbine side power system stabilizer on suppress low frequency oscillation, this paper proposed a design idea about turbine side power system stabilizer, which adopted the classic phase compensation method. At the same time, one parameter setting method of the turbine side power system stabilizer was proposed through the theoretical analysis and mathematical simulation. Based on the platform of MTLAB, the effect and frequency boundary of the turbine side power system stabilizer was analyzed through theoretical analysis and mathematical simulation. This paper also introduced a realization method of the turbine side power system stabilizer which realized as an external device through comparison of the various realization methods, which has done the preparation work for the practical application of the designed turbine side power system stabilizer.
