Use of metamodeling technology in the control of technological regimes of hydroelectric power plants

A conception of metamodeling is discussed and also a technology of 4-level metamodeling, which is important for constructing flexible models assuming efficient reconstruction. The transition to such a technology istoplical, if there is a need in a homogeneous account of the modeled object ’s characteristics determined by characteristics of the problem domain whose account is predominant. An interactive software metamodeling complex LMPL-Software is discussed, it allows to construct a metamodel,applied models of objects on its basis, conduct models transformations bound up with constructing new models from blocks identified in course of analysis. This new technology gives an expert a more efficient way to solve applied problems and, in particular, the problem of constructing a model representation for the process of choosing an optimum operating regime of a hydroelectric power plant. A technology of optimization of control for hydroresources and planning such regimes of hydroelectric power plants is described.
