Identification of the Inertia of Masses Flowing Water through the Pipes in Water Power Plants


Article Preview

In this paper the identification method of the parameter representing the inertia of masses flowing water throw the pipes in water power plants has been presented. The value of this parameter is used in adaptable method of synchronizing power generators. The identification based on the simplified mathematical model of the hydro-turbine and initial phase of the response to synchronizing power object. Application mathematical model compose synchronous generator during idle work, hydro-turbine with long pipes and large head and controller of governor. Identification Tw parameter process consists of two steps. The first step is connected with analyzing initial phase of transient characteristic. And the next point is connected with determinate coefficients of linear flattening and characteristic point. This point is realized by sending control signals of angular velocity from automatic synchronizer to controller. This cause changing frequency of voltage which is the next (point by point) registered in selected moments in matrix. A shown synchronization method is
