Abstract: The thermoeconomic diagnosis in operating power plants is more and more being demanded by the users of the same ones. Nevertheless, in spite of the efforts to unify the techniques or tactics of diagnosis, it seemed that we are even far from standardizing the analytical procedures to do it. Recently, a series of papers have been considered to compare different ways to solve a concrete problem to diagnose a power plants TADEUS part 1–7. In this paper, we look for to establish the minimum requirements that must fulfill the three fundamental aspects in an on-line thermoeconomic diagnosis and monitoring such as: Dynamic Reference Operating State, an Acceptable Performance Test State, and an Equalized Reconciliation Method. Where the Dynamic Reference Operating State, talks about to create a reference on the basis of the atmosphere conditions, fuel quality and present load of the plant in operation; in the Acceptable Operating State Test, we will describe to the minimum requirements of data acquisition and filtrate to have an acceptable tests and comparable with the reference; and an Equalized Reconciliation Method, talks about to the comparison of states (reference versus proves) to conditions of equal load and atmosphere, solved by a module of equation systems; respectively. An example of development and results applied to a plant of combined cycle 240MW of third generation is presented.
