Basic turbine values from data of fault events

Models for power turbines are used to simulate and analyze the load frequency behavior of electrical networks. Basic models for turbines were published in 1973 by the IEEE committee and are implemented in commercial programs, used in text books and commonly accepted in the literature. Nevertheless, only typical values are found in the literature for these models. This is a limiting factor in real grid synthesis and analysis. The main obstacle towards obtaining measured data is the high price of field tests and availability of the power plants. Nevertheless, records from fault events are usually kept by power utilities. In this paper we use data from the Israel Electric Corporation (IEC) to obtain values for several turbines. Our approach is compared against the one recently published in the IEEE Transactions, which requires several field tests for the identification of a load frequency control unit model (LFCUM). In this context we show that the validation of the LFCUM results is insufficient and no justification is apparent for its application.
